Summary for the public


What is Zypadhera?

Zypadhera is a powder and solvent that are made up into a prolonged-release suspension for injection. It contains the active substance olanzapine. ‘Prolonged release’ means that the active substance is released slowly over a few weeks after being injected.


What is Zypadhera used for?

Zypadhera is used to maintain the improvement in symptoms in patients with schizophrenia who have already been stabilised on an initial course of olanzapine taken by mouth. Schizophrenia is a mental illness that has a number of symptoms, including disorganised thinking and speech, hallucinations (hearing or seeing things that are not there), suspiciousness and delusions (false beliefs).

The medicine can only be obtained with a prescription.


How is Zypadhera used?

Zypadhera is given by deep injection into the buttock muscle by a doctor or nurse who has been trained in giving this type of injection. In rare cases, patients receiving Zypadhera may experience symptoms of olanzapine overdose after injection if the medicine is accidentally injected into a vein. Symptoms of overdose include sedation (sleepiness) and delirium (confusion). Because patients should be monitored by qualified staff for these symptoms for at least three hours after injection, they should receive Zypadhera at a centre with the appropriate facilities to deal with a potential overdose. Patients who have symptoms of overdose should continue to be monitored until the symptoms have passed. Zypadhera must not be injected into a vein or under the skin.

Zypadhera is given at doses of 150, 210 or 300 mg every two weeks, or 300 or 405 mg every four weeks. The dose depends on the dose of olanzapine that the patient was previously taking by mouth. Patients should be monitored closely for signs of relapse (a return of symptoms) during the first one to two months of treatment, and the dose adjusted if necessary.

Zypadhera is not recommended for patients over 65 years of age. However, patients aged between 65 and 75 years or patients with kidney or liver problems may use Zypadhera if an effective and well-tolerated dose of oral olanzapine has been found. A lower starting dose may be necessary in patients whose bodies may break olanzapine down slowly, such as those with moderate liver problems.


How does Zypadhera work?

The active substance in Zypadhera, olanzapine, is an antipsychotic medicine. It is known as an ‘atypical’ antipsychotic because it is different from the older antipsychotic medicines that have been available since the 1950s. Olanzapine attaches to several different receptors on the surface of nerve cells in the brain. This disrupts signals transmitted between brain cells by ‘neurotransmitters’, chemicals that allow nerve cells to communicate with each other. It is thought that olanzapine’s beneficial effect is due to it blocking receptors for the neurotransmitters 5-hydroxytrypamine (also called serotonin) and dopamine. Since these neurotransmitters are involved in schizophrenia, olanzapine helps to normalise the activity of the brain, reducing the symptoms of the disease.

Olanzapine has been authorised in the European Union (EU) since 1996. It is available as tablets, orodispersible tablets (tablets that dissolve in the mouth) and rapidly acting injections in Zyprexa, Zyprexa Velotab and other medicines. The olanzapine in Zypadhera is presented as a ‘pamoate’ salt, which makes the olanzapine less soluble. As a result, the active substance is released slowly for more than four weeks after injection of Zypadhera.


How has Zypadhera been studied?

Because olanzapine has already been authorised in the EU as Zyprexa, the company used some of the data from Zyprexa to support the use of Zypadhera.

Zypadhera has been studied in two main studies involving adults with schizophrenia. The first looked at the initial treatment of schizophrenia and the second looked at the maintenance of response to olanzapine treatment:

  • the study of initial treatment compared the effects of three doses of Zypadhera with those of placebo (dummy injections) in 404 patients. The main measure of effectiveness was the change in symptoms measured on a standard scale for schizophrenia after eight weeks;
  • the study of maintenance treatment compared the effects of four doses of Zypadhera with those of olanzapine taken by mouth in 1,065 patients. Three of the doses of Zypadhera were ‘high’ (300 mg and 150 mg every two weeks, and 405 mg every four weeks) and one was ‘low’ (45 mg every four weeks). All of the patients in this study had been stabilised with other treatments for schizophrenia and had been taking olanzapine by mouth for at least six weeks before the study began. The main measures of effectiveness were the time taken for symptoms to get worse and the number of patients whose symptoms got worse over 24 weeks.

What benefit has Zypadhera shown during the studies

In the study of the initial treatment of schizophrenia, Zypadhera was more effective than placebo. Symptom scores were around 100 points at the start of the study, but had fallen by around 25 points in the patients receiving Zypadhera after eight weeks, compared with around 9 points in the patients receiving placebo. The effectiveness of Zypadhera was greater than placebo from the second week of treatment onwards.

In the study looking at the maintenance of response to olanzapine treatment, Zypadhera was as effective as olanzapine taken by mouth: 10% of the patients receiving Zypadhera every two weeks had a worsening of symptoms, compared with 7% of those taking olanzapine by mouth. The ‘high’ doses of Zypadhera were more effective at preventing a worsening of symptoms than the ‘low’ dose.


What is the risk associated with Zypadhera?

The most common side effects with Zypadhera (seen in more than 1 patient in 10) are weight gain, somnolence (sleepiness) and raised levels of prolactin (a hormone). For the full list of all side effects reported with Zypadhera, see the Package Leaflet.

Zypadhera should not be used in patients who may be hypersensitive (allergic) to olanzapine or any of the other ingredients. It must not be used in patients at risk of narrow-angle glaucoma (raised pressure inside the eye).


Why has Zypadhera been approved?

The Committee for Medicinal Products for Human Use (CHMP) noted that Zypadhera is effective both in the initial treatment of schizophrenia and in maintaining a response to treatment in schizophrenia. However, it noted that prolonged-release injections are not suitable for use as initial treatment, because the medicine takes at least a week to reduce symptoms and patients may need rapid control of symptoms. In addition, it is not possible to stop treatment after giving a prolonged-release injection, which would not be suitable for patients experiencing side effects. Therefore, the Committee decided that Zypadhera’s benefits are greater than its risks for maintenance treatment of adult patients with schizophrenia sufficiently stabilised during acute treatment with oral olanzapine. The Committee recommended that Zypadhera be given marketing authorisation.


Which measures are being taken to ensure the safe use of Zypadhera?

The company that makes Zypadhera will provide an educational programme for doctors, nurses and pharmacists and a card for patients in all Member States, reminding them of how to use the medicine safely. These will include information on what to do before and after each injection, the differences between Zypadhera and other injectable medicines containing olanzapine, and the recommendations on how patients should be monitored.

CLINICAL PARTICULARS
4.1 Therapeutic indications
Maintenance treatment of adult patients with schizophrenia sufficiently stabilised during acute
treatment with oral olanzapine.
4.2 Posology and method of administration
FOR INTRAMUSCULAR USE ONLY. DO NOT ADMINISTER INTRAVENOUSLY OR
SUBCUTANEOUSLY. (See section 4.4)
ZYPADHERA should only be administered by deep intramuscular gluteal injection by a healthcare
professional trained in the appropriate injection technique and in locations where post-injection
observation and access to appropriate medical care in the case of overdose can be assured.
After each injection, patients should be observed in a health care facility by appropriately qualified
personnel for at least 3 hours for signs and symptoms consistent with olanzapine overdose. It should
be confirmed that the patient is alert, oriented, and absent of any signs and symptoms of overdose. If
an overdose is suspected, close medical supervision and monitoring should continue until examination
indicates that signs and symptoms have resolved (see section 4.4.).
Patients should be treated initially with oral olanzapine before administering ZYPADHERA, to
establish tolerability and response.
For Instructions for Use, see section 6.6.
Do not confuse ZYPADHERA 210 mg powder and solvent for prolonged release suspension for
injection with olanzapine 10 mg powder for solution for injection.
In order to identify the first ZYPADHERA dose for all patients the scheme in Table 1 should be
considered.

Dose adjustment
Patients should be monitored carefully for signs of relapse during the first one to two months
of treatment. During antipsychotic treatment, improvement in the patient’s clinical condition
may take several days to some weeks. Patients should be closely monitored during this period.
During treatment dose may subsequently be adjusted on the basis of individual clinical status.
After clinical reassessment dose may be adjusted within the range 150 mg to 300 mg every 2
weeks or 300 to 405 mg every 4 weeks. (Table 1)
Supplementation
Supplementation with oral olanzapine was not authorised in double-blind clinical studies. If
oral olanzapine supplementation is clinically indicated, then the combined total dose of
olanzapine from both formulations should not exceed the corresponding maximum oral
olanzapine dose of 20 mg/day.
Switching to other antipsychotic medicinal products
There are no systematically collected data to specifically address switching patients from
ZYPADHERA to other antipsychotic medicinal products. Due to the slow dissolution of the
olanzapine pamoate salt which provides a slow continuous release of olanzapine that is complete
approximately six to eight months after the last injection, supervision by a clinician, especially during
the first 2 months after discontinuation of ZYPADHERA, is needed when switching to another
antipsychotic product and is considered medically appropriate.
Elderly patients
ZYPADHERA has not been systematically studied in elderly patients (> 65 years). ZYPADHERA is
not recommended for treatment in the elderly population unless a well-tolerated and effective dose
regimen using oral olanzapine has been established. A lower starting dose (150 mg/4 weeks) is not
routinely indicated, but should be considered for those 65 and over when clinical factors warrant.
ZYPADHERA is not recommended to be started in patients >75 years (see section 4.4).
Patients with renal and/or hepatic impairment
Unless a well-tolerated and effective dose regimen using oral olanzapine has been established in such
patients, ZYPADHERA should not be used. A lower starting dose (150 mg every 4 weeks) should be
considered for such patients. In cases of moderate hepatic insufficiency (cirrhosis, Child-Pugh Class A
or B), the starting dose should be 150 mg every 4 weeks and only increased with caution.
Gender
The starting dose and dose range need not be routinely altered for female patients relative to male
patients.
Smokers
The starting dose and dose range need not be routinely altered for non-smokers relative to smokers.
When more than one factor is present which might result in slower metabolism (female gender,
geriatric age, non-smoking status), consideration should be given to decreasing the dose. When
indicated, dose escalation should be performed with caution in these patients.
Paediatric population
ZYPADHERA is not recommended for use in children and adolescents below 18 years due to a lack
of data on safety and efficacy.
4.3 Contraindications
3
 
Hypersensitivity to the active substance or to any of the excipients.
Patients with known risk of narrow-angle glaucoma.
4.4 Special warnings and precautions for use
Special care must be taken to apply appropriate injection technique to avoid inadvertent intravascular
or subcutaneous injection (see section 6.6).
Use in patients who are in an acutely agitated or severely psychotic state
ZYPADHERA should not be used to treat patients with schizophrenia who are in an acutely agitated
or severely psychotic state such that immediate symptom control is warranted.
Post-injection syndrome
During pre-marketing clinical studies, reactions that presented with signs and symptoms consistent
with olanzapine overdose, were reported in patients following an injection of ZYPADHERA. These
reactions occurred in <0.1% of injections and approximately 2% of patients. Most of these patients
have developed symptoms of sedation (ranging from mild in severity up to coma) and/or delirium
(including confusion, disorientation, agitation, anxiety and other cognitive impairment). Other
symptoms noted include extrapyramidal symptoms, dysarthria, ataxia, aggression, dizziness,
weakness, hypertension and convulsion. In most cases, initial signs and symptoms related to this
reaction have appeared within 1 hour following injection, and in all cases full recovery was reported to
have occurred within 24 – 72 hours after injection. Reactions occurred rarely (<1 in 1,000 injections)
between 1 and 3 hours, and very rarely (<1 in 10,000 injections) after 3 hours. Patients should be
advised about this potential risk and the need to be observed for 3 hours in a healthcare facility each
time ZYPADHERA is administered.
Prior to giving the injection, the healthcare professional should determine that the patient will not
travel alone to their destination. After each injection, patients should be observed in a healthcare
facility by appropriately qualified personnel for at least 3 hours for signs and symptoms consistent
with olanzapine overdose.
It should be confirmed that the patient is alert, oriented, and absent of any signs and symptoms of
overdose. If an overdose is suspected, close medical supervision and monitoring should continue until
examination indicates that signs and symptoms have resolved.
For the remainder of the day after injection, patients should be advised to be vigilant for signs and
symptoms of overdose secondary to post injection adverse reactions, be able to obtain assistance if
needed and should not drive or operate machinery (see section 4.7).
If parenteral benzodiazepines are essential for management of post injection adverse reactions, careful
evaluation of clinical status for excessive sedation and cardiorespiratory depression is recommended.
(see section 4.5)
Injection site related adverse events
The most commonly reported injection site related adverse reaction was pain. The majority of these
reactions was reported to be of “mild” to “moderate” severity. In the event of an injection site related
adverse reaction occuring, appropriate measures to manage these events should be taken. (see section
4.8)
Dementia-related psychosis and/or behavioural disturbances
Olanzapine is not approved for the treatment of dementia-related psychosis and/or behavioural
disturbances and is not recommended for use in this particular group of patients because of an increase
in mortality and the risk of cerebrovascular accident. In placebo-controlled clinical trials (6-12 weeks
duration) of elderly patients (mean age 78 years) with dementia-related psychosis and/or disturbed
behaviours, there was a 2-fold increase in the incidence of death in oral olanzapine-treated patients
compared to patients treated with placebo (3.5% vs. 1.5%, respectively). The higher incidence of death
4
was not associated with olanzapine dose (mean daily dose 4.4 mg) or duration of treatment. Risk
factors that may predispose this patient population to increased mortality include age > 65 years,
dysphagia, sedation, malnutrition and dehydration, pulmonary conditions (e.g., pneumonia, with or
without aspiration), or concomitant use of benzodiazepines. However, the incidence of death was
higher in oral olanzapine-treated than in placebo-treated patients independent of these risk factors.
In the same clinical trials, cerebrovascular adverse reactions (CVAEvents e.g., stroke, transient
ischemic attack), including fatalities, were reported. There was a 3-fold increase in CVAE in patients
treated with oral olanzapine compared to patients treated with placebo (1.3% vs. 0.4%, respectively).
All oral olanzapine- and placebo-treated patients who experienced a cerebrovascular event had pre-
existing risk factors. Age > 75 years and vascular/mixed type dementia were identified as risk factors
for CVAE in association with olanzapine treatment. The efficacy of olanzapine was not established in
these trials.
Parkinson's disease
The use of olanzapine in the treatment of dopamine agonist associated psychosis in patients with
Parkinson's disease is not recommended. In clinical trials, worsening of Parkinsonian symptomatology
and hallucinations were reported very commonly and more frequently than with placebo (see section
4.8), and oral olanzapine was not more effective than placebo in the treatment of psychotic symptoms.
In these trials, patients were initially required to be stable on the lowest effective dose of anti-
Parkinsonian medicinal products (dopamine agonist) and to remain on the same anti-Parkinsonian
medicinal products and dosages throughout the study. Oral olanzapine was started at 2.5 mg/day and
titrated to a maximum of 15 mg/day based on investigator judgement.
Neuroleptic Malignant Syndrome (NMS)
NMS is a potentially life-threatening condition associated with antipsychotic medicinal products. Rare
cases reported as NMS have also been received in association with oral olanzapine. Clinical
manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of
autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac
dysrhythmia). Additional signs may include elevated creatine phosphokinase, myoglobinuria
(rhabdomyolysis), and acute renal failure. If a patient develops signs and symptoms indicative of
NMS, or presents with unexplained high fever without additional clinical manifestations of NMS, all
antipsychotic medicines, including olanzapine must be discontinued.
Hyperglycaemia and diabetes
Hyperglycaemia and/or development or exacerbation of diabetes occasionally associated with
ketoacidosis or coma has been reported rarely, including some fatal cases (see section 4.8). In some
cases, a prior increase in body weight has been reported which may be a predisposing factor.
Appropriate clinical monitoring is advisable in accordance with utilised antipsychotic guidelines.
Patients treated with any antipsychotic agents, including ZYPADHERA, should be observed for signs
and symptoms of hyperglycaemia (such as polydipsia, polyuria, polyphagia, and weakness) and
patients with diabetes mellitus or with risk factors for diabetes mellitus should be monitored regularly
for worsening of glucose control. Weight should be monitored regularly.
Lipid alterations
Undesirable alterations in lipids have been observed in olanzapine-treated patients in placebo-
controlled clinical trials (see section 4.8). Lipid alterations should be managed as clinically
appropriate, particularly in dyslipidemic patients and in patients with risk factors for the development
of lipids disorders. Patients treated with any antipsychotic agents, including ZYPADHERA, should be
monitored regularly for lipids in accordance with utilised antipsychotic guidelines.
Anticholinergic activity
While olanzapine demonstrated anticholinergic activity in vitro , experience during the clinical trials
revealed a low incidence of related events. However, as clinical experience with olanzapine in patients
with concomitant illness is limited, caution is advised when prescribing for patients with prostatic
hypertrophy, or paralytic ileus and related conditions.
5
Hepatic function
Transient, asymptomatic elevations of hepatic aminotransferases, ALT, AST have been seen
commonly, especially in early treatment. Caution should be exercised and follow-up organised in
patients with elevated ALT and/or AST, in patients with signs and symptoms of hepatic impairment,
in patients with pre-existing conditions associated with limited hepatic functional reserve, and in
patients who are being treated with potentially hepatotoxic medicines. In cases where hepatitis
(including hepatocellular, cholestatic or mixed liver injury) has been diagnosed, olanzapine treatment
should be discontinued.
Neutropenia
Caution should be exercised in patients with low leukocyte and/or neutrophil counts for any reason, in
patients receiving medicines known to cause neutropenia, in patients with a history of drug-induced
bone marrow depression/toxicity, in patients with bone marrow depression caused by concomitant
illness, radiation therapy or chemotherapy and in patients with hypereosinophilic conditions or with
myeloproliferative disease. Neutropenia has been reported commonly when olanzapine and valproate
are used concomitantly (see section 4.8).
Discontinuation of treatment
Acute symptoms such as sweating, insomnia, tremor, anxiety, nausea, or vomiting have been reported
very rarely (<0.01%) when oral olanzapine is stopped abruptly.
QT interval
In clinical trials with oral olanzapine, clinically meaningful QTc prolongations (Fridericia QT
correction [QTcF] ≥ 500 milliseconds [msec] at any time post baseline in patients with baseline
QTcF<500 msec) were uncommon (0.1% to 1%) in patients treated with olanzapine, with no
significant differences in associated cardiac events compared to placebo. In clinical trials with
olanzapine powder for solution for injection or ZYPADHERA, olanzapine was not associated with a
persistent increase in absolute QT or in QTc intervals. However, as with other antipsychotics, caution
should be exercised when olanzapine is prescribed with medicines known to increase QTc interval,
especially in the elderly, in patients with congenital long QT syndrome, congestive heart failure, heart
hypertrophy, hypokalaemia or hypomagnesaemia.
Thromboembolism
Temporal association of olanzapine treatment and venous thromboembolism has very rarely (< 0.01%)
been reported. A causal relationship between the occurrence of venous thromboembolism and
treatment with olanzapine has not been established. However, since patients with schizophrenia often
present with acquired risk factors for venous thromboembolism all possible risk factors of VTE e.g.
immobilisation of patients, should be identified and preventive measures undertaken.
General CNS activity
Given the primary CNS effects of olanzapine, caution should be used when it is taken in combination
with other centrally acting medicines and alcohol. As it exhibits in vitro dopamine antagonism,
olanzapine may antagonize the effects of direct and indirect dopamine agonists.
Seizures
Olanzapine should be used cautiously in patients who have a history of seizures or are subject to
factors which may lower the seizure threshold. Seizures have been reported to occur rarely in patients
when treated with olanzapine. In most of these cases, a history of seizures or risk factors for seizures
were reported.
Tardive dyskinesia
In comparator studies of one year or less duration, olanzapine was associated with a statistically
significant lower incidence of treatment emergent dyskinesia. However the risk of tardive dyskinesia
increases with long term exposure, and therefore if signs or symptoms of tardive dyskinesia appear in
a patient on olanzapine, a dose reduction or discontinuation should be considered. These symptoms
can temporally deteriorate or even arise after discontinuation of treatment.
6
Postural hypotension
Postural hypotension was infrequently observed in the elderly in olanzapine clinical trials. As with
other antipsychotics, it is recommended that blood pressure is measured periodically in patients over
65 years.
Sudden cardiac death
In postmarketing reports with olanzapine, the event of sudden cardiac death has been reported in
patients with olanzapine. In a retrospective observational cohort study, the risk of presumed sudden
cardiac death in patients treated with olanzapine was approximately twice the risk in patients not using
antipsychotics. In the study, the risk of olanzapine was comparable to the risk of atypical
antipsychotics included in a pooled analysis.
Paediatric population
Olanzapine is not indicated for use in the treatment of children and adolescents. Studies in patients
aged 13-17 years showed various adverse reactions, including weight gain, changes in metabolic
parameters and increases in prolactin levels. Long-term outcomes associated with these events have
not been studied and remain unknown (see sections 4.8 and 5.1).
Use in elderly patients (>75 years)
No information on the use of ZYPADHERA in patients >75 years is available. Due to biochemical
and physiological modification and reduction of muscular mass, this formulation is not recommended
to be started in this sub-group of patients.
4.5 Interaction with other medicinal products and other forms of interaction
Paediatric population
Interaction studies have only been performed in adults.
Caution should be exercised in patients who receive medicinal products that can induce hypotension or
sedation.
Potential interactions affecting olanzapine
Since olanzapine is metabolised by CYP1A2, substances that can specifically induce or inhibit this
isoenzyme may affect the pharmacokinetics of olanzapine.
Induction of CYP1A2
The metabolism of olanzapine may be induced by smoking and carbamazepine, which may lead to
reduced olanzapine concentrations. Only slight to moderate increase in olanzapine clearance has been
observed. The clinical consequences are likely to be limited, but clinical monitoring is recommended
and an increase of olanzapine dose may be considered if necessary (see section 4.2).
Inhibition of CYP1A2
Fluvoxamine, a specific CYP1A2 inhibitor, has been shown to significantly inhibit the metabolism of
olanzapine. The mean increase in olanzapine C max following fluvoxamine was 54 % in female non-
smokers and 77 % in male smokers. The mean increase in olanzapine AUC was 52 % and 108 %
respectively. A lower starting dose of olanzapine should be considered in patients who are using
fluvoxamine or any other CYP1A2 inhibitors, such as ciprofloxacin. A decrease in the dose of
olanzapine should be considered if treatment with an inhibitor of CYP1A2 is initiated.
Fluoxetine (a CYP2D6 inhibitor), single doses of antacid (aluminium, magnesium) or cimetidine have
not been found to significantly affect the pharmacokinetics of olanzapine.
Potential for olanzapine to affect other medicinal products
Olanzapine may antagonise the effects of direct and indirect dopamine agonists.
Olanzapine does not inhibit the main CYP450 isoenzymes in vitro (e.g. 1A2, 2D6, 2C9, 2C19, 3A4).
Thus no particular interaction is expected as verified through in vivo studies where no inhibition of
7
metabolism of the following active substances was found: tricyclic antidepressant (representing mostly
CYP2D6 pathway), warfarin (CYP2C9), theophylline (CYP1A2) or diazepam (CYP3A4 and 2C19).
Olanzapine showed no interaction when co-administered with lithium or biperiden.
Therapeutic monitoring of valproate plasma levels did not indicate that valproate dosage adjustment is
required after the introduction of concomitant olanzapine.
General CNS activity
Caution should be exercised in patients who consume alcohol or receive medicinal products that can
cause central nervous system depression.
The concomitant use of olanzapine with anti-Parkinsonian medicinal products in patients with
Parkinson's disease and dementia is not recommended (see section 4.4).
QTc interval
Caution should be used if olanzapine is being administered concomitantly with medicinal products
known to increase QTc interval (see section 4.4).
4.6 Fertility, pregnancy and lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women. Patients should be advised to
notify their physician if they become pregnant or intend to become pregnant during treatment with
olanzapine. Nevertheless, because human experience is limited, olanzapine should be used in
pregnancy only if the potential benefit justifies the potential risk to the foetus.
Spontaneous reports have been very rarely received on tremor, hypertonia, lethargy and sleepiness, in
infants born to mothers who had used olanzapine during the 3rd trimester.
Breast feeding
In a study of oral olanzapine in breast feeding, healthy women, olanzapine was excreted in breast
milk. Mean infant exposure (mg/kg) at steady state was estimated to be 1.8% of the maternal
olanzapine dose (mg/kg). Patients should be advised not to breast feed an infant if they are taking
olanzapine.
4.7 Effects on ability to drive and use machines
No studies on the effects on the ability to drive and use machines have been performed. As olanzapine
may cause somnolence and dizziness, patients should be cautioned about operating machinery,
including motor vehicles.
Patients should be advised not to drive or operate machinery for the remainder of the day after each
injection due to the possibility of a post-injection syndrome event leading to symptoms consistent with
olanzapine overdose (see section 4.4).
4.8 Undesirable effects
Post-injection syndrome reactions have occurred with ZYPADHERA leading to symptoms consistent
with olanzapine overdose (see sections 4.2 and 4.4). Clinical signs and symptoms included symptoms
of sedation (ranging from mild in severity up to coma) and/or delirium (including confusion,
disorientation, agitation, anxiety and other cognitive impairment). Other symptoms noted include
extrapyramidal symptoms, dysarthria, ataxia, aggression, dizziness, weakness, hypertension and
convulsion.
Other adverse reactions observed in patients treated with ZYPADHERA were similar to those seen
with oral olanzapine. In clinical trials with ZYPADHERA, the only adverse reaction reported at a
8
statistically significantly higher rate in the ZYPADHERA group than in the placebo group was
sedation (ZYPADHERA 8.2%, placebo 2.0%). Among all ZYPADHERA treated patients, sedation
was reported by 4.7% of patients .
In clinical trials with ZYPADHERA the incidence of injection site related adverse reactions was
approximately 8%. The most commonly reported injection site related adverse reaction was pain (5%);
some other injection site adverse reactions reported were (in decreasing frequency): nodule type
reactions, erythema type reactions, non-specific injection site reactions, irritation, oedema type
reactions, bruising, haemorrhage, and anaesthesia. These events occurred in about 0.1 to 1.1% of
patients.
The undesirable effects listed below have been observed following administration of oral olanzapine
but may occur following administration of ZYPADHERA.
Adults
The most frequently (seen in ≥ 1% of patients ) reported adverse reactions associated with the use of
olanzapine in clinical trials were somnolence, weight gain, eosinophilia, elevated prolactin,
cholesterol, glucose and triglyceride levels (see section 4.4), glucosuria, increased appetite, dizziness,
akathisia, parkinsonism (see section 4.4), dyskinesia, orthostatic hypotension, anticholinergic effects,
transient asymptomatic elevations of hepatic aminotransferases (see section 4.4), rash, asthenia,
fatigue and oedema.
The following table lists the adverse reactions and laboratory investigations observed from
spontaneous reporting and in clinical trials. Within each frequency grouping, adverse reactions are
presented in order of decreasing seriousness. The frequency terms listed are defined as follows: Very
common (≥10%), common (≥ 1% and < 10%), uncommon (≥ 0.1% and < 1%), rare (≥ 0.01% and
< 0.1%), very rare (< 0.01%), not known (cannot be estimated from the data available).

1 Clinically significant weight gain was observed across all baseline Body Mass Index (BMI)
categories. Following short term treatment (median duration 47 days), weight gain ≥ 7% of baseline
body weight was very common (22.2 %), ≥ 15 % was common (4.2 %) and ≥ 25 % was uncommon
(0.8 %). Patients gaining ≥ 7 %, ≥ 15 % and ≥ 25% of their baseline body weight with long-term
exposure (at least 48 weeks) were very common (64.4 %, 31.7 % and 12.3 % respectively) .
2 Mean increases in fasting lipid values (total cholesterol, LDL cholesterol, and triglycerides) were
greater in patients without evidence of lipid dysregulation at baseline.
10
 
3 Observed for fasting normal levels at baseline (< 5.17 mmol/l) which increased to high
(≥ 6.2 mmol/l). Changes in total fasting cholesterol levels from borderline at baseline (≥ 5.17 -
< 6.2 mmol/l) to high (≥ 6.2 mmol/l) were very common.
4 Observed for fasting normal levels at baseline (< 5.56 mmol/l) which increased to high (≥ 7 mmol/l).
Changes in fasting glucose from borderline at baseline (≥ 5.56 - < 7 mmol/l) to high (≥ 7 mmol/l) were
very common.
5 Observed for fasting normal levels at baseline (< 1.69 mmol/l) which increased to high
(≥ 2.26 mmol/l). Changes in fasting triglycerides from borderline at baseline (≥ 1.69 mmol/l -
< 2.26 mmol/l) to high (≥ 2.26 mmol/l) were very common.
6 In clinical trials, the incidence of Parkinsonism and dystonia in olanzapine-treated patients was
numerically higher, but not statistically significantly different from placebo. Olanzapine-treated
patients had a lower incidence of Parkinsonism, akathisia and dystonia compared with titrated doses of
haloperidol. In the absence of detailed information on the pre-existing history of individual acute and
tardive extrapyramidal movement disorders, it can not be concluded at present that olanzapine
produces less tardive dyskinesia and/or other tardive extrapyramidal syndromes.
7 Acute symptoms such as sweating, insomnia, tremor, anxiety, nausea and vomiting have been
reported when olanzapine is stopped abruptly.
8 In clinical trials of up to 12 weeks, plasma prolactin concentrations exceeded the upper limit of
normal range in approximately 30% of olanzapine treated patients with normal baseline prolactin
value. In the majority of these patients the elevations were generally mild, and remained below two
times the upper limit of normal range. Generally in olanzapine-treated patients potentially associated
breast- and menstrual related clinical manifestations (e.g. amenorrhoea, breast enlargement,
galactorrhea in females, and gynaecomastia/breast enlargement in males) were uncommon. Potentially
associated sexual function-related adverse reactions (e.g. erectile dysfunction in males and decreased
libido in both genders) were commonly observed.
Long-term exposure (at least 48 weeks)
The proportion of patients who had adverse, clinically significant changes in weight gain, glucose,
total/LDL/HDL cholesterol or triglycerides increased over time. In adult patients who completed 9-12
months of therapy, the rate of increase in mean blood glucose slowed after approximately 6 months.
Additional information on special populations
In clinical trials in elderly patients with dementia, olanzapine treatment was associated with a higher
incidence of death and cerebrovascular adverse reactions compared to placebo (see also section 4.4).
Very common adverse reactions associated with the use of olanzapine in this patient group were
abnormal gait and falls. Pneumonia, increased body temperature, lethargy, erythema, visual
hallucinations and urinary incontinence were observed commonly.
In clinical trials in patients with drug-induced (dopamine agonist) psychosis associated with
Parkinson’s disease, worsening of Parkinsonian symptomatology and hallucinations were reported
very commonly and more frequently than with placebo.
In one clinical trial in patients with bipolar mania, valproate combination therapy with olanzapine
resulted in an incidence of neutropenia of 4.1%; a potential contributing factor could be high plasma
valproate levels. Olanzapine administered with lithium or valproate resulted in increased levels
(≥10%) of tremor, dry mouth, increased appetite, and weight gain. Speech disorder was also reported
commonly. During treatment with olanzapine in combination with lithium or divalproex, an increase
of ≥ 7% from baseline body weight occurred in 17.4% of patients during acute treatment (up to 6
weeks). Long-term olanzapine treatment (up to 12 months) for recurrence prevention in patients with
bipolar disorder was associated with an increase of ≥7% from baseline body weight in 39.9% of
patients.
11
Paediatric population
Olanzapine is not indicated for the treatment of children and adolescent patients below 18 years.
Although no clinical studies designed to compare adolescents to adults have been conducted, data
from the adolescent trials were compared to those of the adult trials.
The following table summarises the adverse reactions reported with a greater frequency in adolescent
patients (aged 13-17 years) than in adult patients or adverse reactions only identified during short-term
clinical trials in adolescent patients. Clinically significant weight gain (≥ 7%) appears to occur more
frequently in the adolescent population compared to adults with comparable exposures. The magnitude
of weight gain and the proportion of adolescent patients who had clinically significant weight gain
were greater with long-term exposure (at least 24 weeks) than with short-term exposure.
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.
The frequency terms listed are defined as follows: Very common (≥ 10%), common (≥ 1% and
< 10%).
Metabolism and nutrition disorders
Very common: Weight gain 9 , elevated triglyceride levels 10 , increased appetite.
Common: Elevated cholesterol levels 11
Nervous system disorders
Very common: Sedation (including: hypersomnia, lethargy, somnolence).
Gastrointestinal disorders
Common: Dry mouth
Hepato-biliary disorders
Very common: Elevations of hepatic aminotransferases (ALT/AST; see section 4.4).
Investigations
Very common: Decreased total bilirubin, increased GGT, elevated plasma prolactin levels 12 .
9 Following short term treatment (median duration 22 days), weight gain ≥ 7% of baseline body weight
(kg) was very common (40.6 %), ≥ 15% of baseline body weight was common (7.1 %) and ≥ 25 %
was common (2.5 %). With long-term exposure (at least 24 weeks), 89.4 % gained ≥ 7 %, 55.3 %
gained ≥ 15 % and 29.1 % gained ≥ 25% of their baseline body weight.
10 Observed for fasting normal levels at baseline (< 1.016 mmol/l) which increased to high
(≥ 1.467 mmol/l) and changes in fasting triglycerides from borderline at baseline (≥ 1.016 mmol/l -
< 1.467 mmol/l) to high (≥ 1.467 mmol/l).
11 Changes in total fasting cholesterol levels from normal at baseline (< 4.39 mmol/l) to high
(≥ 5.17 mmol/l) were observed commonly. Changes in total fasting cholesterol levels from borderline
at baseline (≥ 4.39 - < 5.17 mmol/l) to high (≥ 5.17 mmol/l) were very common.
12 Elevated plasma prolactin levels were reported in 47.4% of adolescent patients.
4.9 Overdose
If signs and symptoms of overdose consistent with post injection syndrome are observed, appropriate
supportive measures should be taken (see section 4.4).
While overdose is less likely with parenteral than oral medicinal products, reference information for
oral olanzapine overdose is presented below:
Signs and symptoms
Very common symptoms in overdose (>10% incidence) include tachycardia, agitation/aggressiveness,
dysarthria, various extrapyramidal symptoms, and reduced level of consciousness ranging from
sedation to coma.
12
 
Other medically significant sequelae of overdose include delirium, convulsion, coma, possible
neuroleptic malignant syndrome, respiratory depression, aspiration, hypertension or hypotension,
cardiac arrhythmias (< 2% of overdose cases) and cardiopulmonary arrest. Fatal outcomes have been
reported for acute oral overdoses as low as 450 mg but survival has also been reported following acute
overdose of approximately 2 g of oral olanzapine.
Management of overdose
There is no specific antidote for olanzapine. Symptomatic treatment and monitoring of vital organ
function should be instituted according to clinical presentation, including treatment of hypotension and
circulatory collapse and support of respiratory function. Do not use epinephrine, dopamine, or other
sympathomimetic agents with beta-agonist activity since beta stimulation may worsen hypotension.
Cardiovascular monitoring is necessary to detect possible arrhythmias. Close medical supervision and
monitoring should continue until the patient recovers.

PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: diazepines, oxazepines and thiazepines, ATC code N05AH03.
Olanzapine is an antipsychotic, antimanic and mood stabilising agent that demonstrates a broad
pharmacologic profile across a number of receptor systems.
In preclinical studies, olanzapine exhibited a range of receptor affinities (K i ; < 100 nM) for serotonin
5-HT 2A/2C , 5-HT 3 , 5-HT 6 ; dopamine D 1 , D 2 , D 3 , D 4 , D 5 ; cholinergic muscarinic receptors M 1 -M 5 ; α- 1
adrenergic; and histamine H 1 receptors. Animal behavioural studies with olanzapine indicated 5HT,
dopamine, and cholinergic antagonism, consistent with the receptor-binding profile. Olanzapine
demonstrated a greater in vitro affinity for serotonin 5-HT 2 than dopamine D 2 receptors and greater 5-
HT 2 than D 2 activity in viv o, models. Electrophysiological studies demonstrated that olanzapine
selectively reduced the firing of mesolimbic (A10) dopaminergic neurons, while having little effect on
the striatal (A9) pathways involved in motor function. Olanzapine reduced a conditioned avoidance
response, a test indicative of antipsychotic activity, at doses below those producing catalepsy, an effect
indicative of motor side-effects. Unlike some other antipsychotic agents, olanzapine increases
responding in an “anxiolytic” test.
The effectiveness of ZYPADHERA in the treatment and maintenance treatment of schizophrenia is
consistent with the established effectiveness of the oral formulation of olanzapine.
In a Positron Emission Tomography (PET) study in patients treated with ZYPADHERA
(300 mg/4 weeks), mean D 2 receptor occupancy was 60% or higher at the end of a 6 month period, a
level consistent with that found during treatment with oral olanzapine.
A total of 1469 patients with schizophrenia were included in 2 pivotal trials:
The first, an 8-week, placebo controlled trial conducted in adult patients (n=404) who were
experiencing acute psychotic symptoms. Patients were randomized to receive injections of
ZYPADHERA 405 mg every 4 weeks, 300 mg every 2 weeks, 210 mg every 2 weeks, or placebo
every 2 weeks. No oral antipsychotic supplementation was allowed. Total Positive and Negative
Symptom Scores (PANSS) showed significant improvement from baseline (baseline mean Total
PANSS Score 101) to endpoint (mean changes -22.57, -26.32, -22.49 respectively) with each dose of
ZYPADHERA (405 mg every 4 weeks, 300 mg every 2 weeks, and 210 mg every 2 weeks) as
compared to placebo (mean change -8.51). Visitwise mean change from baseline to endpoint in
PANSS Total score indicated that by Day 3, patients in the 300 mg/2 weeks and 405 mg/4 weeks
treatment groups had statistically significantly greater reductions in PANSS Total score compared to
placebo (-8.6, -8.2, and -5.2, respectively). All 3 ZYPADHERA treatment groups showed statistically
significantly greater improvement than placebo beginning by end of Week 1. These results support
13
efficacy for ZYPADHERA over 8 weeks of treatment and a drug effect that was observed as early as
1 week after starting treatment with ZYPADHERA.
The second, a long term study in clinically stable patients (n=1065) (baseline mean Total PANSS
Score 54.33 to 57.75) who were initially treated with oral olanzapine for 4 to 8 weeks and then
switched to continue on oral olanzapine or to ZYPADHERA for 24 weeks. No oral antipsychotic
supplementation was allowed. ZYPADHERA treatment groups of 150 mg and 300 mg given every 2
weeks (doses pooled for analysis) and 405 mg given every 4 weeks were non inferior to the combined
doses of 10, 15 and 20 mg of oral olanzapine (doses pooled for analysis) as measured by rates of
exacerbation of symptoms of schizophrenia (respective exacerbation rates, 10%, 10% 7%).
Exacerbation was measured by worsening of items on the PANSS derived BPRS Positive scale and
hospitalization due to worsening of positive psychotic symptoms. The combined 150 mg and
300 mg/2 week treatment group was non inferior to the 405 mg/4 week treatment group (exacerbation
rates 10% for each group) at 24 weeks after randomisation.
Paediatric population
ZYPADHERA has not been studied in the paediatric population . The experience in adolescents (ages
13 to 17 years) is limited to short term oral olanzapine efficacy data in schizophrenia (6 weeks) and
mania associated with bipolar I disorder (3 weeks), involving less than 200 adolescents. Oral
olanzapine was used as a flexible dose starting with 2.5 and ranging up to 20 mg/day. During
treatment with oral olanzapine, adolescents gained significantly more weight compared with adults.
The magnitude of changes in fasting total cholesterol, LDL cholesterol, triglycerides, and prolactin
(see sections 4.4 and 4.8) were greater in adolescents than in adults. There are no data on maintenance
of effect and limited data on long term safety (see sections 4.4 and 4.8) .
5.2 Pharmacokinetic properties
Olanzapine is metabolised in the liver by conjugative and oxidative pathways. The major circulating
metabolite is the 10-N-glucuronide. Cytochromes P450-CYP1A2 and P450-CYP2D6 contribute to the
formation of the N-desmethyl and 2-hydroxymethyl metabolites; both exhibited significantly less in
vivo pharmacological activity than olanzapine in animal studies. The predominant pharmacologic
activity is from the parent, olanzapine.
After a single IM injection with ZYPADHERA the slow dissolution of the olanzapine pamoate salt in
muscle tissue begins immediately and provides a slow continuous release of olanzapine for more than
four weeks. The release becomes diminishingly smaller within eight to twelve weeks. Antipsychotic
supplementation is not required at the initiation of ZYPADHERA treatment (see section 4.2).
The combination of the release profile and the dosage regimen (IM injection every two or four weeks)
result in sustained olanzapine plasma concentrations. Plasma concentrations remain measurable for
several months after each ZYPADHERA injection. The half-life of olanzapine after ZYPADHERA is
30 days compared to 30 hours following oral administration. The absorption and elimination are
complete approximately six to eight months after the last injection.
Oral olanzapine is rapidly distributed. The plasma protein binding of olanzapine is about 93% over the
concentration range of 7 to about 1000 ng/mL. In plasma, olanzapine is bound to albumin and α1-acid
glycoprotein.
Olanzapine plasma clearance after oral olanzapine is lower in females (18.9 l/hr) versus males
(27.3 l/hr), and in non-smokers (18.6 l/hr) versus smokers (27.7 l/hr). Similar pharmacokinetic
differences between males and females and smokers and nonsmokers were observed in ZYPADHERA
clinical trials. However, the magnitude of the impact of gender, or smoking on olanzapine clearance is
small in comparison to the overall variability between individuals.
After repeated IM injections with 150 to 300 mg ZYPADHERA every two weeks, the 10 th to 90 th
percentile of steady-state plasma concentrations of olanzapine were between 4.2 and 73.2 ng/ml. The
plasma concentrations of olanzapine observed across the dose range of 150mg every 4 weeks to
14
300mg every 2 weeks illustrate increased systemic olanzapine exposure with increased ZYPADHERA
doses. During the initial three months of treatment with ZYPADHERA, accumulation of olanzapine
was observed but there was no additional accumulation during long-term use (12 months) in patients
who were injected with up to 300 mg every two weeks.
No specific investigations have been conducted in the elderly with ZYPADHERA. ZYPADHERA is
not recommended for treatment in the elderly population (65 years and over) unless a well-tolerated
and effective dosage regimen using oral olanzapine has been established. In healthy elderly (65 and
over) versus non-elderly subjects, the mean elimination half-life was prolonged (51.8 versus
33.8 hours) and the clearance was reduced (17.5 versus 18.2 l/hr). The pharmacokinetic variability
observed in the elderly is within the range for the non-elderly. In 44 patients with schizophrenia >65
years of age, dosing from 5 to 20 mg/day was not associated with any distinguishing profile of adverse
events.
In renally impaired patients (creatinine clearance < 10 ml/min) versus healthy subjects, there was no
significant difference in mean elimination half-life (37.7 versus 32.4 hours) or clearance (21.2 versus
25.0 l/hr). A mass balance study showed that approximately 57% of radiolabelled olanzapine appeared
in urine, principally as metabolites. Although patients with renal impairment were not studied with
ZYPADHERA, it is recommended that a well-tolerated and effective dosage regimen using oral
olanzapine is established in patients with renal impairment before treatment with ZYPADHERA is
initiated (see section 4.2).
In smoking subjects with mild hepatic dysfunction, mean elimination half-life (39.3 hours) of orally
administered olanzapine was prolonged and clearance (18.0 l/hr) was reduced analogous to non-
smoking healthy subjects (48.8 hours and 14.1 l/hr, respectively). Although patients with hepatic
impairment were not studied with ZYPADHERA, it is recommended that a well-tolerated and
effective dosage regimen using oral olanzapine is established in patients with hepatic impairment
before treatment with ZYPADHERA is initiated (see section 4.2).
In a study of oral olanzapine given to Caucasians, Japanese, and Chinese subjects, there were no
differences in the pharmacokinetic parameters among the three populations.
5.3 Preclinical safety data
Preclinical safety studies were performed using olanzapine pamoate monohydrate. The main findings
found in repeat-dose toxicity studies (rat, dog), in a 2-year rat carcinogenicity study, and in toxicity to
reproduction studies (rat, rabbit) were limited to injection site reactions for which no NOAEL could be
determined. No new toxic effect resulting from systemic exposure to olanzapine could be identified.
However, systemic concentrations in these studies were generally less than that seen at effect levels in
the oral studies; thus the information on oral olanzapine is provided below for reference.
Acute (single-dose) toxicity
Signs of oral toxicity in rodents were characteristic of potent antipsychotic compounds: hypoactivity,
coma, tremors, clonic convulsions, salivation, and depressed weight gain. The median lethal doses
were approximately 210 mg/kg (mice) and 175 mg/kg (rats). Dogs tolerated single oral doses up to
100 mg/kg without mortality. Clinical signs included sedation, ataxia, tremors, increased heart rate,
laboured respiration, miosis, and anorexia. In monkeys, single oral doses up to 100 mg/kg resulted in
prostration and, at higher doses, semi-consciousness.
Repeated-dose toxicity
In studies up to 3 months duration in mice and up to 1 year in rats and dogs, the predominant effects
were CNS depression, anticholinergic effects, and peripheral haematological disorders. Tolerance
developed to the CNS depression. Growth parameters were decreased at high doses. Reversible effects
consistent with elevated prolactin in rats included decreased weights of ovaries and uterus and
morphologic changes in vaginal epithelium and in mammary gland.
15
Haematologic toxicity: Effects on haematology parameters were found in each species, including
dose-related reductions in circulating leukocytes in mice and non-specific reductions of circulating
leukocytes in rats; however, no evidence of bone marrow cytotoxicity was found. Reversible
neutropenia, thrombocytopenia, or anaemia developed in a few dogs treated with 8 or 10 mg/kg/day
(total olanzapine exposure [AUC] is 12- to 15-fold greater than that of a man given a 12 mg dose). In
cytopenic dogs, there were no undesirable effects on progenitor and proliferating cells in the bone
marrow.
Reproductive toxicity
Olanzapine had no teratogenic effects. Sedation affected mating performance of male rats. Oestrous
cycles were affected at doses of 1.1 mg/kg (3 times the maximum human dose) and reproduction
parameters were influenced in rats given 3 mg/kg (9 times the maximum human dose). In the offspring
of rats given olanzapine, delays in foetal development and transient decreases in offspring activity
levels were seen.
Mutagenicity
Olanzapine was not mutagenic or clastogenic in a full range of standard tests, which included bacterial
mutation tests and in vitro and oral in vivo mammalian tests.
Carcinogenicity
Based on the results of oral studies in mice and rats, it was concluded that olanzapine is not
carcinogenic.

It is important to note that there is more solvent in the vial than is needed to reconstitute.
STEP 3: Reconstituting ZYPADHERA
1. Loosen the powder by lightly tapping the vial.
2. Open the pre-packaged Hypodermic Needle-Pro syringe and needle with needle protection device.
Peel blister pouch and remove device. Insure needle is firmly seated on the Needle-Pro device
with a push and a clockwise twist, then pull the needle cap straight away from the needle. Failure
to follow these instructions may result in a needlestick injury.
3. Withdraw the pre-determined solvent volume (Step 2) into the syringe.
4. Inject the solvent volume into the powder vial.
5. Withdraw air to equalize the pressure in the vial.
6. Remove the needle, holding the vial upright to prevent any loss of solvent.
7. Engage the needle safety device. Press the needle into the sheath using a one-handed technique.
Perform a one-handed technique by GENTLY pressing the sheath against a flat surface. AS THE
SHEATH IS PRESSED, THE NEEDLE IS FIRMLY ENGAGED INTO THE SHEATH (Figure 1
and 2)
8. Visually confirm that the needle is fully engaged into the needle protection sheath. (Figure 3) Only
remove the Needle-Pro device with the engaged needle from the syringe when required by a
specific medical procedure. Remove by grasping the Luer hub of the needle protection device with
17
 
thumb and forefinger, keeping the free fingers clear of the end of the device containing the needle
point.

9. Tap the vial firmly and repeatedly on a hard surface until no powder is visible. Protect the surface
to cushion impact. (See Figure A)
Figure A: Tap firmly to mix
10. Visually check the vial for clumps. Unsuspended powder appears as yellow, dry clumps clinging
to the vial. Additional tapping may be required if clumps remain. (See Figure B)
Unsuspended: visible clumps Suspended: no clumps
Figure B: Check for unsuspended powder and repeat tapping if needed .
11. Shake the vial vigorously until the suspension appears smooth and is consistent in color and
texture. The suspended product will be yellow and opaque. (See Figure C)
Figure C: Vigorously shake vial
If foam forms, let vial stand to allow foam to dissipate. If the product is not used immediately, it
should be shaken vigorously to re-suspend. Reconstituted ZYPADHERA remains stable for up to
24 hours in the vial.

1. Determine which needle will be used to administer the injection to the patient. For obese patients,
the 50 mm needle is recommended for injection:
If the 50 mm needle is to be used for injection, attach the 38 mm safety needle to the syringe to
withdraw the required suspension volume.
If the 38 mm needle is to be used for the injection, attach the 50 mm safety needle to withdraw
the required suspension volume
2. Slowly withdraw the desired amount. Some excess product will remain in the vial.
3. Engage the needle safety device and remove needle from syringe.
4. Attach the remaining safety needle to the syringe prior to injection. Once the suspension has been
removed from the vial, it should be injected immediately.
5. Select and prepare a site for injection in the gluteal area. DO NOT INJECT INTRAVENOUSLY
OR SUBCUTANEOUSLY.
6. After insertion of the needle, aspirate for several seconds to ensure no blood appears. If any blood
is drawn into the syringe, discard the syringe and the dose and begin reconstitution and
administration procedure again. The injection should be performed with steady, continuous
pressure.
DO NOT MASSAGE THE INJECTION SITE.
7. Engage the needle safety device. (Figure 1 and 2)
8. Discard the vials, syringe, needles and any unused solvent in accordance with appropriate clinical
procedures. The vial is for single use only.

CLINICAL PARTICULARS
4.1 Therapeutic indications
Maintenance treatment of adult patients with schizophrenia sufficiently stabilised during acute
treatment with oral olanzapine.
4.2 Posology and method of administration
FOR INTRAMUSCULAR USE ONLY. DO NOT ADMINISTER INTRAVENOUSLY OR
SUBCUTANEOUSLY. (see section 4.4)
ZYPADHERA should only be administered by deep intramuscular gluteal injection by a healthcare
professional trained in the appropriate injection technique and in locations where post-injection
observation and access to appropriate medical care in the case of overdose can be assured.
After each injection, patients should be observed in a health care facility by appropriately qualified
personnel for at least 3 hours for signs and symptoms consistent with olanzapine overdose. It should
be confirmed that the patient is alert, oriented, and absent of any signs and symptoms of overdose. If
an overdose is suspected, close medical supervision and monitoring should continue until examination
indicates that signs and symptoms have resolved (see section 4.4.).
Patients should be treated initially with oral olanzapine before administering ZYPADHERA,
to establish tolerability and response.
For Instructions for Use, see section 6.6.
Do not confuse ZYPADHERA 300 mg powder and solvent for prolonged release suspension for
injection with olanzapine 10 mg powder for solution for injection.
In order to identify the first ZYPADHERA dose for all patients the scheme in Table 1 should be
considered.

Dose adjustment
Patients should be monitored carefully for signs of relapse during the first one to two months
of treatment. During antipsychotic treatment, improvement in the patient’s clinical condition
may take several days to some weeks. Patients should be closely monitored during this period.
During treatment dose may subsequently be adjusted on the basis of individual clinical status.
After clinical reassessment dose may be adjusted within the range 150 mg to 300 mg every
2 weeks or 300 to 405 mg every 4 weeks. (Table 1)
Supplementation
Supplementation with oral olanzapine was not authorised in double-blind clinical studies. If
oral olanzapine supplementation is clinically indicated, then the combined total dose of
olanzapine from both formulations should not exceed the corresponding maximum oral
olanzapine dose of 20 mg/day.
Switching to other antipsychotic medicinal products
There are no systematically collected data to specifically address switching patients from
ZYPADHERA to other antipsychotic medicinal products. Due to the slow dissolution of the
olanzapine pamoate salt which provides a slow continuous release of olanzapine that is complete
approximately six to eight months after the last injection, supervision by a clinician, especially during
the first 2 months after discontinuation of ZYPADHERA, is needed when switching to another
antipsychotic product and is considered medically appropriate.
Elderly patients
ZYPADHERA has not been systematically studied in elderly patients (> 65 years). ZYPADHERA is
not recommended for treatment in the elderly population unless a well-tolerated and effective dose
regimen using oral olanzapine has been established. A lower starting dose (150 mg/4 weeks) is not
routinely indicated, but should be considered for those 65 and over when clinical factors warrant.
ZYPADHERA is not recommended to be started in patients >75 years (see section 4.4).
Patients with renal and/or hepatic impairment
Unless a well-tolerated and effective dose regimen using oral olanzapine has been established in such
patients, ZYPADHERA should not be used. A lower starting dose (150 mg every 4 weeks) should be
considered for such patients. In cases of moderate hepatic insufficiency (cirrhosis, Child-Pugh Class A
or B), the starting dose should be 150 mg every 4 weeks and only increased with caution.
Gender
The starting dose and dose range need not be routinely altered for female patients relative to male
patients.
Smokers
The starting dose and dose range need not be routinely altered for non-smokers relative to smokers.
When more than one factor is present which might result in slower metabolism (female gender,
geriatric age, non-smoking status), consideration should be given to decreasing the dose. When
indicated, dose escalation should be performed with caution in these patients.
Paediatric population
ZYPADHERA is not recommended for use in children and adolescents below 18 years due to a lack
of data on safety and efficacy.
4.3 Contraindications
21
 
Hypersensitivity to the active substance or to any of the excipients.
Patients with known risk of narrow-angle glaucoma.
4.4 Special warnings and precautions for use
Special care must be taken to apply appropriate injection technique to avoid inadvertent intravascular
or subcutaneous injection (see section 6.6).
Use in patients who are in an acutely agitated or severely psychotic state
ZYPADHERA should not be used to treat patients with schizophrenia who are in an acutely agitated
or severely psychotic state such that immediate symptom control is warranted.
Post-injection syndrome
During pre-marketing clinical studies, reactions that presented with signs and symptoms consistent
with olanzapine overdose, were reported in patients following an injection of ZYPADHERA. These
reactions occurred in <0.1% of injections and approximately 2% of patients. Most of these patients
have developed symptoms of sedation (ranging from mild in severity up to coma) and/or delirium
(including confusion, disorientation, agitation, anxiety and other cognitive impairment). Other
symptoms noted include extrapyramidal symptoms, dysarthria, ataxia, aggression, dizziness,
weakness, hypertension and convulsion. In most cases, initial signs and symptoms related to this
reaction have appeared within 1 hour following injection, and in all cases full recovery was reported to
have occurred within 24 – 72 hours after injection. Reactions occurred rarely (<1 in 1,000 injections)
between 1 and 3 hours, and very rarely (<1 in 10,000 injections) after 3 hours. Patients should be
advised about this potential risk and the need to be observed for 3 hours in a healthcare facility each
time ZYPADHERA is administered.
Prior to giving the injection, the healthcare professional should determine that the patient will not
travel alone to their destination. After each injection, patients should be observed in a healthcare
facility by appropriately qualified personnel for at least 3 hours for signs and symptoms consistent
with olanzapine overdose.
It should be confirmed that the patient is alert, oriented, and absent of any signs and symptoms of
overdose. If an overdose is suspected, close medical supervision and monitoring should continue until
examination indicates that signs and symptoms have resolved.
For the remainder of the day after injection, patients should be advised to be vigilant for signs and
symptoms of overdose secondary to post injection adverse reactions, be able to obtain assistance if
needed and should not drive or operate machinery (see section 4.7).
If parenteral benzodiazepines are essential for management of post injection adverse reactions, careful
evaluation of clinical status for excessive sedation and cardiorespiratory depression is recommended.
(see section 4.5)
Injection site related adverse events
The most commonly reported injection site related adverse reaction was pain. The majority of these
reactions was reported to be of “mild” to “moderate” severity. In the event of an injection site related
adverse reaction occuring, appropriate measures to manage these events should be taken. (see
section 4.8)
Dementia-related psychosis and/or behavioural disturbances
Olanzapine is not approved for the treatment of dementia-related psychosis and/or behavioural
disturbances and is not recommended for use in this particular group of patients because of an increase
in mortality and the risk of cerebrovascular accident. In placebo-controlled clinical trials (6-12 weeks
duration) of elderly patients (mean age 78 years) with dementia-related psychosis and/or disturbed
behaviours, there was a 2-fold increase in the incidence of death in oral olanzapine-treated patients
compared to patients treated with placebo (3.5% vs. 1.5%, respectively). The higher incidence of death
22
was not associated with olanzapine dose (mean daily dose 4.4 mg) or duration of treatment. Risk
factors that may predispose this patient population to increased mortality include age > 65 years,
dysphagia, sedation, malnutrition and dehydration, pulmonary conditions (e.g., pneumonia, with or
without aspiration), or concomitant use of benzodiazepines. However, the incidence of death was
higher in oral olanzapine-treated than in placebo-treated patients independent of these risk factors.
In the same clinical trials, cerebrovascular adverse reactions (CVAEvents e.g., stroke, transient
ischemic attack), including fatalities, were reported. There was a 3-fold increase in CVAE in patients
treated with oral olanzapine compared to patients treated with placebo (1.3% vs. 0.4%, respectively).
All oral olanzapine- and placebo-treated patients who experienced a cerebrovascular event had pre-
existing risk factors. Age > 75 years and vascular/mixed type dementia were identified as risk factors
for CVAE in association with olanzapine treatment. The efficacy of olanzapine was not established in
these trials.
Parkinson's disease
The use of olanzapine in the treatment of dopamine agonist associated psychosis in patients with
Parkinson's disease is not recommended. In clinical trials, worsening of Parkinsonian symptomatology
and hallucinations were reported very commonly and more frequently than with placebo (see section
4.8), and oral olanzapine was not more effective than placebo in the treatment of psychotic symptoms.
In these trials, patients were initially required to be stable on the lowest effective dose of anti-
Parkinsonian medicinal products (dopamine agonist) and to remain on the same anti-Parkinsonian
medicinal products and dosages throughout the study. Oral olanzapine was started at 2.5 mg/day and
titrated to a maximum of 15 mg/day based on investigator judgement.
Neuroleptic Malignant Syndrome (NMS)
NMS is a potentially life-threatening condition associated with antipsychotic medicinal products. Rare
cases reported as NMS have also been received in association with oral olanzapine. Clinical
manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of
autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac
dysrhythmia). Additional signs may include elevated creatine phosphokinase, myoglobinuria
(rhabdomyolysis), and acute renal failure. If a patient develops signs and symptoms indicative of
NMS, or presents with unexplained high fever without additional clinical manifestations of NMS, all
antipsychotic medicines, including olanzapine must be discontinued.
Hyperglycaemia and diabetes
Hyperglycaemia and/or development or exacerbation of diabetes occasionally associated with
ketoacidosis or coma has been reported rarely, including some fatal cases (see section 4.8). In some
cases, a prior increase in body weight has been reported which may be a predisposing factor.
Appropriate clinical monitoring is advisable in accordance with utilised antipsychotic guidelines.
Patients treated with any antipsychotic agents, including ZYPADHERA, should be observed for signs
and symptoms of hyperglycaemia (such as polydipsia, polyuria, polyphagia, and weakness) and
patients with diabetes mellitus or with risk factors for diabetes mellitus should be monitored regularly
for worsening of glucose control. Weight should be monitored regularly.
Lipid alterations
Undesirable alterations in lipids have been observed in olanzapine-treated patients in placebo-
controlled clinical trials (see section 4.8). Lipid alterations should be managed as clinically
appropriate, particularly in dyslipidemic patients and in patients with risk factors for the development
of lipids disorders. Patients treated with any antipsychotic agents, including ZYPADHERA, should be
monitored regularly for lipids in accordance with utilised antipsychotic guidelines.
Anticholinergic activity
While olanzapine demonstrated anticholinergic activity in vitro , experience during the clinical trials
revealed a low incidence of related events. However, as clinical experience with olanzapine in patients
with concomitant illness is limited, caution is advised when prescribing for patients with prostatic
hypertrophy, or paralytic ileus and related conditions.
23
Hepatic function
Transient, asymptomatic elevations of hepatic aminotransferases, ALT, AST have been seen
commonly, especially in early treatment. Caution should be exercised and follow-up organised in
patients with elevated ALT and/or AST, in patients with signs and symptoms of hepatic impairment,
in patients with pre-existing conditions associated with limited hepatic functional reserve, and in
patients who are being treated with potentially hepatotoxic medicines. In cases where hepatitis
(including hepatocellular, cholestatic or mixed liver injury) has been diagnosed, olanzapine treatment
should be discontinued.
Neutropenia
Caution should be exercised in patients with low leukocyte and/or neutrophil counts for any reason, in
patients receiving medicines known to cause neutropenia, in patients with a history of drug-induced
bone marrow depression/toxicity, in patients with bone marrow depression caused by concomitant
illness, radiation therapy or chemotherapy and in patients with hypereosinophilic conditions or with
myeloproliferative disease. Neutropenia has been reported commonly when olanzapine and valproate
are used concomitantly (see section 4.8).
Discontinuation of treatment
Acute symptoms such as sweating, insomnia, tremor, anxiety, nausea, or vomiting have been reported
very rarely (<0.01%) when oral olanzapine is stopped abruptly.
QT interval
In clinical trials with oral olanzapine, clinically meaningful QTc prolongations (Fridericia QT
correction [QTcF] ≥ 500 milliseconds [msec] at any time post baseline in patients with baseline
QTcF<500 msec) were uncommon (0.1% to 1%) in patients treated with olanzapine, with no
significant differences in associated cardiac events compared to placebo. In clinical trials with
olanzapine powder for solution for injection or ZYPADHERA, olanzapine was not associated with a
persistent increase in absolute QT or in QTc intervals. However, as with other antipsychotics, caution
should be exercised when olanzapine is prescribed with medicines known to increase QTc interval,
especially in the elderly, in patients with congenital long QT syndrome, congestive heart failure, heart
hypertrophy, hypokalaemia or hypomagnesaemia.
Thromboembolism
Temporal association of olanzapine treatment and venous thromboembolism has very rarely (< 0.01%)
been reported. A causal relationship between the occurrence of venous thromboembolism and
treatment with olanzapine has not been established. However, since patients with schizophrenia often
present with acquired risk factors for venous thromboembolism all possible risk factors of VTE e.g.
immobilisation of patients, should be identified and preventive measures undertaken.
General CNS activity
Given the primary CNS effects of olanzapine, caution should be used when it is taken in combination
with other centrally acting medicines and alcohol. As it exhibits in vitro dopamine antagonism,
olanzapine may antagonize the effects of direct and indirect dopamine agonists.
Seizures
Olanzapine should be used cautiously in patients who have a history of seizures or are subject to
factors which may lower the seizure threshold. Seizures have been reported to occur rarely in patients
when treated with olanzapine. In most of these cases, a history of seizures or risk factors for seizures
were reported.
Tardive dyskinesia
In comparator studies of one year or less duration, olanzapine was associated with a statistically
significant lower incidence of treatment emergent dyskinesia. However the risk of tardive dyskinesia
increases with long term exposure, and therefore if signs or symptoms of tardive dyskinesia appear in
a patient on olanzapine, a dose reduction or discontinuation should be considered. These symptoms
can temporally deteriorate or even arise after discontinuation of treatment.
24
Postural hypotension
Postural hypotension was infrequently observed in the elderly in olanzapine clinical trials. As with
other antipsychotics, it is recommended that blood pressure is measured periodically in patients over
65 years.
Sudden cardiac death
In postmarketing reports with olanzapine, the event of sudden cardiac death has been reported in
patients with olanzapine. In a retrospective observational cohort study, the risk of presumed sudden
cardiac death in patients treated with olanzapine was approximately twice the risk in patients not using
antipsychotics. In the study, the risk of olanzapine was comparable to the risk of atypical
antipsychotics included in a pooled analysis.
Paediatric population
Olanzapine is not indicated for use in the treatment of children and adolescents. Studies in patients
aged 13-17 years showed various adverse reactions, including weight gain, changes in metabolic
parameters and increases in prolactin levels. Long-term outcomes associated with these events have
not been studied and remain unknown (see sections 4.8 and 5.1).
Use in elderly patients (>75 years)
No information on the use of ZYPADHERA in patients >75 years is available. Due to biochemical
and physiological modification and reduction of muscular mass, this formulation is not recommended
to be started in this sub-group of patients.
4.5 Interaction with other medicinal products and other forms of interaction
Paediatric population
Interaction studies have only been performed in adults.
Caution should be exercised in patients who receive medicinal products that can induce hypotension or
sedation.
Potential interactions affecting olanzapine
Since olanzapine is metabolised by CYP1A2, substances that can specifically induce or inhibit this
isoenzyme may affect the pharmacokinetics of olanzapine.
Induction of CYP1A2
The metabolism of olanzapine may be induced by smoking and carbamazepine, which may lead to
reduced olanzapine concentrations. Only slight to moderate increase in olanzapine clearance has been
observed. The clinical consequences are likely to be limited, but clinical monitoring is recommended
and an increase of olanzapine dose may be considered if necessary (see section 4.2).
Inhibition of CYP1A2
Fluvoxamine, a specific CYP1A2 inhibitor, has been shown to significantly inhibit the metabolism of
olanzapine. The mean increase in olanzapine C max following fluvoxamine was 54 % in female non-
smokers and 77 % in male smokers. The mean increase in olanzapine AUC was 52 % and 108 %
respectively. A lower starting dose of olanzapine should be considered in patients who are using
fluvoxamine or any other CYP1A2 inhibitors, such as ciprofloxacin. A decrease in the dose of
olanzapine should be considered if treatment with an inhibitor of CYP1A2 is initiated.
Fluoxetine (a CYP2D6 inhibitor), single doses of antacid (aluminium, magnesium) or cimetidine have
not been found to significantly affect the pharmacokinetics of olanzapine.
Potential for olanzapine to affect other medicinal products
Olanzapine may antagonise the effects of direct and indirect dopamine agonists.
Olanzapine does not inhibit the main CYP450 isoenzymes in vitro (e.g. 1A2, 2D6, 2C9, 2C19, 3A4).
Thus no particular interaction is expected as verified through in vivo studies where no inhibition of
25
metabolism of the following active substances was found: tricyclic antidepressant (representing mostly
CYP2D6 pathway), warfarin (CYP2C9), theophylline (CYP1A2) or diazepam (CYP3A4 and 2C19).
Olanzapine showed no interaction when co-administered with lithium or biperiden.
Therapeutic monitoring of valproate plasma levels did not indicate that valproate dosage adjustment is
required after the introduction of concomitant olanzapine.
General CNS activity
Caution should be exercised in patients who consume alcohol or receive medicinal products that can
cause central nervous system depression.
The concomitant use of olanzapine with anti-Parkinsonian medicinal products in patients with
Parkinson's disease and dementia is not recommended (see section 4.4).
QTc interval
Caution should be used if olanzapine is being administered concomitantly with medicinal products
known to increase QTc interval (see section 4.4).
4.6 Fertility, pregnancy and lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women. Patients should be advised to
notify their physician if they become pregnant or intend to become pregnant during treatment with
olanzapine. Nevertheless, because human experience is limited, olanzapine should be used in
pregnancy only if the potential benefit justifies the potential risk to the foetus.
Spontaneous reports have been very rarely received on tremor, hypertonia, lethargy and sleepiness, in
infants born to mothers who had used olanzapine during the 3rd trimester.
Breast feeding
In a study of oral olanzapine in breast feeding, healthy women, olanzapine was excreted in breast
milk. Mean infant exposure (mg/kg) at steady state was estimated to be 1.8% of the maternal
olanzapine dose (mg/kg). Patients should be advised not to breast feed an infant if they are taking
olanzapine.
4.7 Effects on ability to drive and use machines
No studies on the effects on the ability to drive and use machines have been performed. As olanzapine
may cause somnolence and dizziness, patients should be cautioned about operating machinery,
including motor vehicles.
Patients should be advised not to drive or operate machinery for the remainder of the day after each
injection due to the possibility of a post-injection syndrome event leading to symptoms consistent with
olanzapine overdose (see section 4.4).
4.8 Undesirable effects
Post-injection syndrome reactions have occurred with ZYPADHERA leading to symptoms consistent
with olanzapine overdose (see sections 4.2 and 4.4). Clinical signs and symptoms included symptoms
of sedation (ranging from mild in severity up to coma) and/or delirium (including confusion,
disorientation, agitation, anxiety and other cognitive impairment). Other symptoms noted include
extrapyramidal symptoms, dysarthria, ataxia, aggression, dizziness, weakness, hypertension and
convulsion.
Other adverse reactions observed in patients treated with ZYPADHERA were similar to those seen
with oral olanzapine. In clinical trials with ZYPADHERA, the only adverse reaction reported at a
26
statistically significantly higher rate in the ZYPADHERA group than in the placebo group was
sedation (ZYPADHERA 8.2%, placebo 2.0%). Among all ZYPADHERA treated patients, sedation
was reported by 4.7% of patients .
In clinical trials with ZYPADHERA the incidence of injection site related adverse reactions was
approximately 8%. The most commonly reported injection site related adverse reaction was pain (5%);
some other injection site adverse reactions reported were (in decreasing frequency): nodule type
reactions, erythema type reactions, non-specific injection site reactions, irritation, oedema type
reactions, bruising, haemorrhage, and anaesthesia. These events occurred in about 0.1 to 1.1% of
patients.
The undesirable effects listed below have been observed following administration of oral olanzapine
but may occur following administration of ZYPADHERA.
Adults
The most frequently (seen in ≥ 1% of patients ) reported adverse reactions associated with the use of
olanzapine in clinical trials were somnolence, weight gain, eosinophilia, elevated prolactin,
cholesterol, glucose and triglyceride levels (see section 4.4), glucosuria, increased appetite, dizziness,
akathisia, parkinsonism (see section 4.4), dyskinesia, orthostatic hypotension, anticholinergic effects,
transient asymptomatic elevations of hepatic aminotransferases (see section 4.4), rash, asthenia,
fatigue and oedema.
The following table lists the adverse reactions and laboratory investigations observed from
spontaneous reporting and in clinical trials. Within each frequency grouping, adverse reactions are
presented in order of decreasing seriousness. The frequency terms listed are defined as follows: Very
common (≥10%), common (≥ 1% and < 10%), uncommon (≥ 0.1% and < 1%), rare (≥ 0.01% and

1 Clinically significant weight gain was observed across all baseline Body Mass Index (BMI)
categories. Following short term treatment (median duration 47 days), weight gain ≥ 7% of baseline
body weight was very common (22.2%), ≥ 15 % was common (4.2 %) and ≥ 25 % was uncommon
(0.8 %). Patients gaining ≥ 7 %, ≥ 15 % and ≥ 25% of their baseline body weight with long-term
exposure (at least 48 weeks) were very common (64.4 %, 31.7 % and 12.3 % respectively) .
2 Mean increases in fasting lipid values (total cholesterol, LDL cholesterol, and triglycerides) were
greater in patients without evidence of lipid dysregulation at baseline.
28
 
3 Observed for fasting normal levels at baseline (< 5.17 mmol/l) which increased to high
(≥ 6.2 mmol/l). Changes in total fasting cholesterol levels from borderline at baseline (≥ 5.17 -
< 6.2 mmol/l) to high (≥ 6.2 mmol/l) were very common.
4 Observed for fasting normal levels at baseline (< 5.56 mmol/l) which increased to high (≥ 7 mmol/l).
Changes in fasting glucose from borderline at baseline (≥ 5.56 - < 7 mmol/l) to high (≥ 7 mmol/l) were
very common.
5 Observed for fasting normal levels at baseline (< 1.69 mmol/l) which increased to high
(≥ 2.26 mmol/l). Changes in fasting triglycerides from borderline at baseline (≥ 1.69 mmol/l -
< 2.26 mmol/l) to high (≥ 2.26 mmol/l) were very common.
6 In clinical trials, the incidence of Parkinsonism and dystonia in olanzapine-treated patients was
numerically higher, but not statistically significantly different from placebo. Olanzapine-treated
patients had a lower incidence of Parkinsonism, akathisia and dystonia compared with titrated doses of
haloperidol. In the absence of detailed information on the pre-existing history of individual acute and
tardive extrapyramidal movement disorders, it can not be concluded at present that olanzapine
produces less tardive dyskinesia and/or other tardive extrapyramidal syndromes.
7 Acute symptoms such as sweating, insomnia, tremor, anxiety, nausea and vomiting have been
reported when olanzapine is stopped abruptly.
8 In clinical trials of up to 12 weeks, plasma prolactin concentrations exceeded the upper limit of
normal range in approximately 30% of olanzapine treated patients with normal baseline prolactin
value. In the majority of these patients the elevations were generally mild, and remained below two
times the upper limit of normal range. Generally in olanzapine-treated patients potentially associated
breast- and menstrual related clinical manifestations (e.g. amenorrhoea, breast enlargement,
galactorrhea in females, and gynaecomastia/breast enlargement in males) were uncommon. Potentially
associated sexual function-related adverse reactions (e.g. erectile dysfunction in males and decreased
libido in both genders) were commonly observed.
Long-term exposure (at least 48 weeks)
The proportion of patients who had adverse, clinically significant changes in weight gain, glucose,
total/LDL/HDL cholesterol or triglycerides increased over time. In adult patients who completed 9-12
months of therapy, the rate of increase in mean blood glucose slowed after approximately 6 months.
Additional information on special populations
In clinical trials in elderly patients with dementia, olanzapine treatment was associated with a higher
incidence of death and cerebrovascular adverse reactions compared to placebo (see also section 4.4).
Very common adverse reactions associated with the use of olanzapine in this patient group were
abnormal gait and falls. Pneumonia, increased body temperature, lethargy, erythema, visual
hallucinations and urinary incontinence were observed commonly.
In clinical trials in patients with drug-induced (dopamine agonist) psychosis associated with
Parkinson’s disease, worsening of Parkinsonian symptomatology and hallucinations were reported
very commonly and more frequently than with placebo.
In one clinical trial in patients with bipolar mania, valproate combination therapy with olanzapine
resulted in an incidence of neutropenia of 4.1%; a potential contributing factor could be high plasma
valproate levels. Olanzapine administered with lithium or valproate resulted in increased levels
(≥10%) of tremor, dry mouth, increased appetite, and weight gain. Speech disorder was also reported
commonly. During treatment with olanzapine in combination with lithium or divalproex, an increase
of ≥ 7% from baseline body weight occurred in 17.4% of patients during acute treatment (up to 6
weeks). Long-term olanzapine treatment (up to 12 months) for recurrence prevention in patients with
bipolar disorder was associated with an increase of ≥7% from baseline body weight in 39.9% of
patients.
29
Paediatric population
Olanzapine is not indicated for the treatment of children and adolescent patients below 18 years.
Although no clinical studies designed to compare adolescents to adults have been conducted, data
from the adolescent trials were compared to those of the adult trials.
The following table summarises the adverse reactions reported with a greater frequency in adolescent
patients (aged 13-17 years) than in adult patients or adverse reactions only identified during short-term
clinical trials in adolescent patients. Clinically significant weight gain (≥ 7%) appears to occur more
frequently in the adolescent population compared to adults with comparable exposures. The magnitude
of weight gain and the proportion of adolescent patients who had clinically significant weight gain
were greater with long-term exposure (at least 24 weeks) than with short-term exposure.
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.
The frequency terms listed are defined as follows: Very common (≥ 10%), common (≥ 1% and
< 10%).
Metabolism and nutrition disorders
Very common: Weight gain 9 , elevated triglyceride levels 10 , increased appetite.
Common: Elevated cholesterol levels 11
Nervous system disorders
Very common: Sedation (including: hypersomnia, lethargy, somnolence).
Gastrointestinal disorders
Common: Dry mouth
Hepato-biliary disorders
Very common: Elevations of hepatic aminotransferases (ALT/AST; see section 4.4).
Investigations
Very common: Decreased total bilirubin, increased GGT, elevated plasma prolactin levels 12 .
9 Following short term treatment (median duration 22 days), weight gain ≥ 7% of baseline body weight
(kg) was very common (40.6 %), ≥ 15% of baseline body weight was common (7.1 %) and ≥ 25 %
was common (2.5%). With long-term exposure (at least 24 weeks), 89.4 % gained ≥ 7 %, 55.3 %
gained ≥ 15 % and 29.1 % gained ≥ 25% of their baseline body weight.
10 Observed for fasting normal levels at baseline (< 1.016 mmol/l) which increased to high
(≥ 1.467 mmol/l) and changes in fasting triglycerides from borderline at baseline (≥ 1.016 mmol/l -
< 1.467 mmol/l) to high (≥ 1.467 mmol/l).
11 Changes in total fasting cholesterol levels from normal at baseline (< 4.39 mmol/l) to high
(≥ 5.17 mmol/l) were observed commonly. Changes in total fasting cholesterol levels from borderline
at baseline (≥ 4.39 - < 5.17 mmol/l) to high (≥ 5.17 mmol/l) were very common.
12 Elevated plasma prolactin levels were reported in 47.4% of adolescent patients.
4.9 Overdose
If signs and symptoms of overdose consistent with post injection syndrome are observed, appropriate
supportive measures should be taken (see section 4.4).
While overdose is less likely with parenteral than oral medicinal products, reference information for
oral olanzapine overdose is presented below:
Signs and symptoms
Very common symptoms in overdose (>10% incidence) include tachycardia, agitation/aggressiveness,
dysarthria, various extrapyramidal symptoms, and reduced level of consciousness ranging from
sedation to coma.
30
 
Other medically significant sequelae of overdose include delirium, convulsion, coma, possible
neuroleptic malignant syndrome, respiratory depression, aspiration, hypertension or hypotension,
cardiac arrhythmias (< 2% of overdose cases) and cardiopulmonary arrest. Fatal outcomes have been
reported for acute oral overdoses as low as 450 mg but survival has also been reported following acute
overdose of approximately 2 g of oral olanzapine.
Management of overdose
There is no specific antidote for olanzapine. Symptomatic treatment and monitoring of vital organ
function should be instituted according to clinical presentation, including treatment of hypotension and
circulatory collapse and support of respiratory function. Do not use epinephrine, dopamine, or other
sympathomimetic agents with beta-agonist activity since beta stimulation may worsen hypotension.
Cardiovascular monitoring is necessary to detect possible arrhythmias. Close medical supervision and
monitoring should continue until the patient recovers.

PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: diazepines, oxazepines and thiazepines, ATC code N05AH03.
Olanzapine is an antipsychotic, antimanic and mood stabilising agent that demonstrates a broad
pharmacologic profile across a number of receptor systems.
In preclinical studies, olanzapine exhibited a range of receptor affinities (K i ; < 100 nM) for serotonin
5-HT 2A/2C , 5-HT 3 , 5-HT 6 ; dopamine D 1 , D 2 , D 3 , D 4 , D 5 ; cholinergic muscarinic receptors M 1 -M 5 ; α- 1
adrenergic; and histamine H 1 receptors. Animal behavioural studies with olanzapine indicated 5HT,
dopamine, and cholinergic antagonism, consistent with the receptor-binding profile. Olanzapine
demonstrated a greater in vitro affinity for serotonin 5-HT 2 than dopamine D 2 receptors and greater 5-
HT 2 than D 2 activity in viv o, models. Electrophysiological studies demonstrated that olanzapine
selectively reduced the firing of mesolimbic (A10) dopaminergic neurons, while having little effect on
the striatal (A9) pathways involved in motor function. Olanzapine reduced a conditioned avoidance
response, a test indicative of antipsychotic activity, at doses below those producing catalepsy, an effect
indicative of motor side-effects. Unlike some other antipsychotic agents, olanzapine increases
responding in an “anxiolytic” test.
The effectiveness of ZYPADHERA in the treatment and maintenance treatment of schizophrenia is
consistent with the established effectiveness of the oral formulation of olanzapine.
In a Positron Emission Tomography (PET) study in patients treated with ZYPADHERA
(300 mg/4 weeks), mean D 2 receptor occupancy was 60% or higher at the end of a 6 month period, a
level consistent with that found during treatment with oral olanzapine.
A total of 1469 patients with schizophrenia were included in 2 pivotal trials:
The first, an 8-week, placebo controlled trial conducted in adult patients (n=404) who were
experiencing acute psychotic symptoms. Patients were randomized to receive injections of
ZYPADHERA 405 mg every 4 weeks, 300 mg every 2 weeks, 210 mg every 2 weeks, or placebo
every 2 weeks. No oral antipsychotic supplementation was allowed. Total Positive and Negative
Symptom Scores (PANSS) showed significant improvement from baseline (baseline mean Total
PANSS Score 101) to endpoint (mean changes -22.57, -26.32, -22.49 respectively) with each dose of
ZYPADHERA (405 mg every 4 weeks, 300 mg every 2 weeks, and 210 mg every 2 weeks) as
compared to placebo (mean change -8.51). Visitwise mean change from baseline to endpoint in
PANSS Total score indicated that by Day 3, patients in the 300 mg/2 weeks and 405 mg/4 weeks
treatment groups had statistically significantly greater reductions in PANSS Total score compared to
placebo (-8.6, -8.2, and -5.2, respectively). All 3 ZYPADHERA treatment groups showed statistically
significantly greater improvement than placebo beginning by end of Week 1. These results support
31
efficacy for ZYPADHERA over 8 weeks of treatment and a drug effect that was observed as early as
1 week after starting treatment with ZYPADHERA.
The second, a long term study in clinically stable patients (n=1065) (baseline mean Total PANSS
Score 54.33 to 57.75) who were initially treated with oral olanzapine for 4 to 8 weeks and then
switched to continue on oral olanzapine or to ZYPADHERA for 24 weeks. No oral antipsychotic
supplementation was allowed. ZYPADHERA treatment groups of 150 mg and 300 mg given every 2
weeks (doses pooled for analysis) and 405 mg given every 4 weeks were non inferior to the combined
doses of 10, 15 and 20 mg of oral olanzapine (doses pooled for analysis) as measured by rates of
exacerbation of symptoms of schizophrenia (respective exacerbation rates, 10%, 10% 7%).
Exacerbation was measured by worsening of items on the PANSS derived BPRS Positive scale and
hospitalization due to worsening of positive psychotic symptoms. The combined 150 mg and
300 mg/2 week treatment group was non inferior to the 405 mg/4 week treatment group (exacerbation
rates 10% for each group) at 24 weeks after randomisation.
Paediatric population
ZYPADHERA has not been studied in the paediatric population . The experience in adolescents (ages
13 to 17 years) is limited to short term oral olanzapine efficacy data in schizophrenia (6 weeks) and
mania associated with bipolar I disorder (3 weeks), involving less than 200 adolescents. Oral
olanzapine was used as a flexible dose starting with 2.5 and ranging up to 20 mg/day. During
treatment with oral olanzapine, adolescents gained significantly more weight compared with adults.
The magnitude of changes in fasting total cholesterol, LDL cholesterol, triglycerides, and prolactin
(see sections 4.4 and 4.8) were greater in adolescents than in adults. There are no data on maintenance
of effect and limited data on long term safety (see sections 4.4 and 4.8) .
5.2 Pharmacokinetic properties
Olanzapine is metabolised in the liver by conjugative and oxidative pathways. The major circulating
metabolite is the 10-N-glucuronide. Cytochromes P450-CYP1A2 and P450-CYP2D6 contribute to the
formation of the N-desmethyl and 2-hydroxymethyl metabolites; both exhibited significantly less in
vivo pharmacological activity than olanzapine in animal studies. The predominant pharmacologic
activity is from the parent, olanzapine.
After a single IM injection with ZYPADHERA the slow dissolution of the olanzapine pamoate salt in
muscle tissue begins immediately and provides a slow continuous release of olanzapine for more than
four weeks. The release becomes diminishingly smaller within eight to twelve weeks. Antipsychotic
supplementation is not required at the initiation of ZYPADHERA treatment (see section 4.2).
The combination of the release profile and the dosage regimen (IM injection every two or four weeks)
result in sustained olanzapine plasma concentrations. Plasma concentrations remain measurable for
several months after each ZYPADHERA injection. The half-life of olanzapine after ZYPADHERA is
30 days compared to 30 hours following oral administration. The absorption and elimination are
complete approximately six to eight months after the last injection.
Oral olanzapine is rapidly distributed. The plasma protein binding of olanzapine is about 93% over the
concentration range of 7 to about 1000 ng/mL. In plasma, olanzapine is bound to albumin and α1-acid
glycoprotein.
Olanzapine plasma clearance after oral olanzapine is lower in females (18.9 l/hr) versus males
(27.3 l/hr), and in non-smokers (18.6 l/hr) versus smokers (27.7 l/hr). Similar pharmacokinetic
differences between males and females and smokers and nonsmokers were observed in ZYPADHERA
clinical trials. However, the magnitude of the impact of gender, or smoking on olanzapine clearance is
small in comparison to the overall variability between individuals.
After repeated IM injections with 150 to 300 mg ZYPADHERA every two weeks, the 10 th to 90 th
percentile of steady-state plasma concentrations of olanzapine were between 4.2 and 73.2 ng/ml. The
plasma concentrations of olanzapine observed across the dose range of 150mg every 4 weeks to
32
300mg every 2 weeks illustrate increased systemic olanzapine exposure with increased ZYPADHERA
doses. During the initial three months of treatment with ZYPADHERA, accumulation of olanzapine
was observed but there was no additional accumulation during long-term use (12 months) in patients
who were injected with up to 300 mg every two weeks.
No specific investigations have been conducted in the elderly with ZYPADHERA. ZYPADHERA is
not recommended for treatment in the elderly population (65 years and over) unless a well-tolerated
and effective dosage regimen using oral olanzapine has been established. In healthy elderly (65 and
over) versus non-elderly subjects, the mean elimination half-life was prolonged (51.8 versus
33.8 hours) and the clearance was reduced (17.5 versus 18.2 l/hr). The pharmacokinetic variability
observed in the elderly is within the range for the non-elderly. In 44 patients with schizophrenia >65
years of age, dosing from 5 to 20 mg/day was not associated with any distinguishing profile of adverse
events.
In renally impaired patients (creatinine clearance < 10 ml/min) versus healthy subjects, there was no
significant difference in mean elimination half-life (37.7 versus 32.4 hours) or clearance (21.2 versus
25.0 l/hr). A mass balance study showed that approximately 57% of radiolabelled olanzapine appeared
in urine, principally as metabolites. Although patients with renal impairment were not studied with
ZYPADHERA, it is recommended that a well-tolerated and effective dosage regimen using oral
olanzapine is established in patients with renal impairment before treatment with ZYPADHERA is
initiated (see section 4.2).
In smoking subjects with mild hepatic dysfunction, mean elimination half-life (39.3 hours) of orally
administered olanzapine was prolonged and clearance (18.0 l/hr) was reduced analogous to non-
smoking healthy subjects (48.8 hours and 14.1 l/hr, respectively). Although patients with hepatic
impairment were not studied with ZYPADHERA, it is recommended that a well-tolerated and
effective dosage regimen using oral olanzapine is established in patients with hepatic impairment
before treatment with ZYPADHERA is initiated (see section 4.2).
In a study of oral olanzapine given to Caucasians, Japanese, and Chinese subjects, there were no
differences in the pharmacokinetic parameters among the three populations.
5.3 Preclinical safety data
Preclinical safety studies were performed using olanzapine pamoate monohydrate. The main findings
found in repeat-dose toxicity studies (rat, dog), in a 2-year rat carcinogenicity study, and in toxicity to
reproduction studies (rat, rabbit) were limited to injection site reactions for which no NOAEL could be
determined. No new toxic effect resulting from systemic exposure to olanzapine could be identified.
However, systemic concentrations in these studies were generally less than that seen at effect levels in
the oral studies; thus the information on oral olanzapine is provided below for reference.
Acute (single-dose) toxicity
Signs of oral toxicity in rodents were characteristic of potent antipsychotic compounds: hypoactivity,
coma, tremors, clonic convulsions, salivation, and depressed weight gain. The median lethal doses
were approximately 210 mg/kg (mice) and 175 mg/kg (rats). Dogs tolerated single oral doses up to
100 mg/kg without mortality. Clinical signs included sedation, ataxia, tremors, increased heart rate,
laboured respiration, miosis, and anorexia. In monkeys, single oral doses up to 100 mg/kg resulted in
prostration and, at higher doses, semi-consciousness.
Repeated-dose toxicity
In studies up to 3 months duration in mice and up to 1 year in rats and dogs, the predominant effects
were CNS depression, anticholinergic effects, and peripheral haematological disorders. Tolerance
developed to the CNS depression. Growth parameters were decreased at high doses. Reversible effects
consistent with elevated prolactin in rats included decreased weights of ovaries and uterus and
morphologic changes in vaginal epithelium and in mammary gland.
33
Haematologic toxicity: Effects on haematology parameters were found in each species, including
dose-related reductions in circulating leukocytes in mice and non-specific reductions of circulating
leukocytes in rats; however, no evidence of bone marrow cytotoxicity was found. Reversible
neutropenia, thrombocytopenia, or anaemia developed in a few dogs treated with 8 or 10 mg/kg/day
(total olanzapine exposure [AUC] is 12- to 15-fold greater than that of a man given a 12 mg dose). In
cytopenic dogs, there were no undesirable effects on progenitor and proliferating cells in the bone
marrow.
Reproductive toxicity
Olanzapine had no teratogenic effects. Sedation affected mating performance of male rats. Oestrous
cycles were affected at doses of 1.1 mg/kg (3 times the maximum human dose) and reproduction
parameters were influenced in rats given 3 mg/kg (9 times the maximum human dose). In the offspring
of rats given olanzapine, delays in foetal development and transient decreases in offspring activity
levels were seen.
Mutagenicity
Olanzapine was not mutagenic or clastogenic in a full range of standard tests, which included bacterial
mutation tests and in vitro and oral in vivo mammalian tests.
Carcinogenicity
Based on the results of oral studies in mice and rats, it was concluded that olanzapine is not
carcinogenic.

It is important to note that there is more solvent in the vial than is needed to reconstitute.
STEP 3: Reconstituting ZYPADHERA
1. Loosen the powder by lightly tapping the vial.
2. Open the pre-packaged Hypodermic Needle-Pro syringe and needle with needle protection device.
Peel blister pouch and remove device. Insure needle is firmly seated on the Needle-Pro device
with a push and a clockwise twist, then pull the needle cap straight away from the needle. Failure
to follow these instructions may result in a needlestick injury.
3. Withdraw the pre-determined solvent volume (Step 2) into the syringe.
4. Inject the solvent volume into the powder vial.
5. Withdraw air to equalize the pressure in the vial.
6. Remove the needle, holding the vial upright to prevent any loss of solvent.
7. Engage the needle safety device. Press the needle into the sheath using a one-handed technique.
Perform a one-handed technique by GENTLY pressing the sheath against a flat surface. AS THE
SHEATH IS PRESSED, THE NEEDLE IS FIRMLY ENGAGED INTO THE SHEATH (Figure 1
and 2)
8. Visually confirm that the needle is fully engaged into the needle protection sheath. (Figure 3) Only
remove the Needle-Pro device with the engaged needle from the syringe when required by a
specific medical procedure. Remove by grasping the Luer hub of the needle protection device with
35
 
thumb and forefinger, keeping the free fingers clear of the end of the device containing the needle
point.

9. Tap the vial firmly and repeatedly on a hard surface until no powder is visible. Protect the surface
to cushion impact. (See Figure A)
Figure A: Tap firmly to mix
10. Visually check the vial for clumps. Unsuspended powder appears as yellow, dry clumps clinging
to the vial. Additional tapping may be required if clumps remain. (See Figure B)
Unsuspended: visible clumps Suspended: no clumps
Figure B: Check for unsuspended powder and repeat tapping if needed .
11. Shake the vial vigorously until the suspension appears smooth and is consistent in color and
texture. The suspended product will be yellow and opaque. (See Figure C)
Figure C: Vigorously shake vial
If foam forms, let vial stand to allow foam to dissipate. If the product is not used immediately, it
should be shaken vigorously to re-suspend. Reconstituted ZYPADHERA remains stable for up to
24 hours in the vial.

1. Determine which needle will be used to administer the injection to the patient. For obese patients,
the 50 mm needle is recommended for injection:
If the 50 mm needle is to be used for injection, attach the 38 mm safety needle to the syringe to
withdraw the required suspension volume.
If the 38 mm needle is to be used for the injection, attach the 50 mm safety needle to withdraw the
required suspension volume
2. Slowly withdraw the desired amount. Some excess product will remain in the vial.
3. Engage the needle safety device and remove needle from syringe.
4. Attach the remaining safety needle to the syringe prior to injection. Once the suspension has been
removed from the vial, it should be injected immediately.
5. Select and prepare a site for injection in the gluteal area. DO NOT INJECT INTRAVENOUSLY
OR SUBCUTANEOUSLY.
6. After insertion of the needle, aspirate for several seconds to ensure no blood appears. If any blood
is drawn into the syringe, discard the syringe and the dose and begin reconstitution and
administration procedure again. The injection should be performed with steady, continuous
pressure.
DO NOT MASSAGE THE INJECTION SITE.
7. Engage the needle safety device. (Figure 1 and 2)
8. Discard the vials, syringe, needles and any unused solvent in accordance with appropriate clinical
procedures. The vial is for single use only.

CLINICAL PARTICULARS
4.1 Therapeutic indications
Maintenance treatment of adult patients with schizophrenia sufficiently stabilised during acute
treatment with oral olanzapine.
4.2 Posology and method of administration
FOR INTRAMUSCULAR USE ONLY. DO NOT ADMINISTER INTRAVENOUSLY OR
SUBCUTANEOUSLY. (See section 4.4)
ZYPADHERA should only be administered by deep intramuscular gluteal injection by a healthcare
professional trained in the appropriate injection technique and in locations where post-injection
observation and access to appropriate medical care in the case of overdose can be assured.
After each injection, patients should be observed in a health care facility by appropriately qualified
personnel for at least 3 hours for signs and symptoms consistent with olanzapine overdose. It should
be confirmed that the patient is alert, oriented, and absent of any signs and symptoms of overdose. If
an overdose is suspected, close medical supervision and monitoring should continue until examination
indicates that signs and symptoms have resolved (see section 4.4.).
Patients should be treated initially with oral olanzapine before administering ZYPADHERA, to
establish tolerability and response.
For Instructions for Use, see section 6.6.
Do not confuse ZYPADHERA 405 mg powder and solvent for prolonged release suspension for
injection with olanzapine 10 mg powder for solution for injection.
In order to identify the first ZYPADHERA dose for all patients the scheme in Table 1 should be
considered.

Dose adjustment
Patients should be monitored carefully for signs of relapse during the first one to two months
of treatment. During antipsychotic treatment, improvement in the patient’s clinical condition
may take several days to some weeks. Patients should be closely monitored during this period.
During treatment dose may subsequently be adjusted on the basis of individual clinical status.
After clinical reassessment dose may be adjusted within the range 150 mg to 300 mg every 2
weeks or 300 to 405 mg every 4 weeks. (Table 1)
Supplementation
Supplementation with oral olanzapine was not authorised in double-blind clinical studies. If
oral olanzapine supplementation is clinically indicated, then the combined total dose of
olanzapine from both formulations should not exceed the corresponding maximum oral
olanzapine dose of 20 mg/day.
Switching to other antipsychotic medicinal products
There are no systematically collected data to specifically address switching patients from
ZYPADHERA to other antipsychotic medicinal products. Due to the slow dissolution of the
olanzapine pamoate salt which provides a slow continuous release of olanzapine that is complete
approximately six to eight months after the last injection, supervision by a clinician, especially during
the first 2 months after discontinuation of ZYPADHERA, is needed when switching to another
antipsychotic product and is considered medically appropriate.
Elderly patients
ZYPADHERA has not been systematically studied in elderly patients (> 65 years). ZYPADHERA is
not recommended for treatment in the elderly population unless a well-tolerated and effective dose
regimen using oral olanzapine has been established. A lower starting dose (150 mg/4 weeks) is not
routinely indicated, but should be considered for those 65 and over when clinical factors warrant.
ZYPADHERA is not recommended to be started in patients >75 years (see section 4.4).
Patients with renal and/or hepatic impairment
Unless a well-tolerated and effective dose regimen using oral olanzapine has been established in such
patients, ZYPADHERA should not be used. A lower starting dose (150 mg every 4 weeks) should be
considered for such patients. In cases of moderate hepatic insufficiency (cirrhosis, Child-Pugh Class A
or B), the starting dose should be 150 mg every 4 weeks and only increased with caution.
Gender
The starting dose and dose range need not be routinely altered for female patients relative to male
patients.
Smokers
The starting dose and dose range need not be routinely altered for non-smokers relative to smokers.
When more than one factor is present which might result in slower metabolism (female gender,
geriatric age, non-smoking status), consideration should be given to decreasing the dose. When
indicated, dose escalation should be performed with caution in these patients.
Paediatric population
ZYPADHERA is not recommended for use in children and adolescents below 18 years due to a lack
of data on safety and efficacy.
4.3 Contraindications
39
 
Hypersensitivity to the active substance or to any of the excipients.
Patients with known risk of narrow-angle glaucoma.
4.4 Special warnings and precautions for use
Special care must be taken to apply appropriate injection technique to avoid inadvertent intravascular
or subcutaneous injection (see section 6.6).
Use in patients who are in an acutely agitated or severely psychotic state
ZYPADHERA should not be used to treat patients with schizophrenia who are in an acutely agitated
or severely psychotic state such that immediate symptom control is warranted.
Post-injection syndrome
During pre-marketing clinical studies, reactions that presented with signs and symptoms consistent
with olanzapine overdose, were reported in patients following an injection of ZYPADHERA. These
reactions occurred in <0.1% of injections and approximately 2% of patients. Most of these patients
have developed symptoms of sedation (ranging from mild in severity up to coma) and/or delirium
(including confusion, disorientation, agitation, anxiety and other cognitive impairment). Other
symptoms noted include extrapyramidal symptoms, dysarthria, ataxia, aggression, dizziness,
weakness, hypertension and convulsion. In most cases, initial signs and symptoms related to this
reaction have appeared within 1 hour following injection, and in all cases full recovery was reported to
have occurred within 24 – 72 hours after injection. Reactions occurred rarely (<1 in 1,000 injections)
between 1 and 3 hours, and very rarely (<1 in 10,000 injections) after 3 hours. Patients should be
advised about this potential risk and the need to be observed for 3 hours in a healthcare facility each
time ZYPADHERA is administered.
Prior to giving the injection, the healthcare professional should determine that the patient will not
travel alone to their destination. After each injection, patients should be observed in a healthcare
facility by appropriately qualified personnel for at least 3 hours for signs and symptoms consistent
with olanzapine overdose.
It should be confirmed that the patient is alert, oriented, and absent of any signs and symptoms of
overdose. If an overdose is suspected, close medical supervision and monitoring should continue until
examination indicates that signs and symptoms have resolved.
For the remainder of the day after injection, patients should be advised to be vigilant for signs and
symptoms of overdose secondary to post injection adverse reactions, be able to obtain assistance if
needed and should not drive or operate machinery (see section 4.7).
If parenteral benzodiazepines are essential for management of post injection adverse reactions, careful
evaluation of clinical status for excessive sedation and cardiorespiratory depression is recommended.
(see section 4.5)
Injection site related adverse events
The most commonly reported injection site related adverse reaction was pain. The majority of these
reactions was reported to be of “mild” to “moderate” severity. In the event of an injection site related
adverse reaction occuring, appropriate measures to manage these events should be taken. (see section
4.8)
Dementia-related psychosis and/or behavioural disturbances
Olanzapine is not approved for the treatment of dementia-related psychosis and/or behavioural
disturbances and is not recommended for use in this particular group of patients because of an increase
in mortality and the risk of cerebrovascular accident. In placebo-controlled clinical trials (6-12 weeks
duration) of elderly patients (mean age 78 years) with dementia-related psychosis and/or disturbed
behaviours, there was a 2-fold increase in the incidence of death in oral olanzapine-treated patients
compared to patients treated with placebo (3.5% vs. 1.5%, respectively). The higher incidence of death
40
was not associated with olanzapine dose (mean daily dose 4.4 mg) or duration of treatment. Risk
factors that may predispose this patient population to increased mortality include age > 65 years,
dysphagia, sedation, malnutrition and dehydration, pulmonary conditions (e.g., pneumonia, with or
without aspiration), or concomitant use of benzodiazepines. However, the incidence of death was
higher in oral olanzapine-treated than in placebo-treated patients independent of these risk factors.
In the same clinical trials, cerebrovascular adverse reactions (CVAEvents e.g., stroke, transient
ischemic attack), including fatalities, were reported. There was a 3-fold increase in CVAE in patients
treated with oral olanzapine compared to patients treated with placebo (1.3% vs. 0.4%, respectively).
All oral olanzapine- and placebo-treated patients who experienced a cerebrovascular event had pre-
existing risk factors. Age > 75 years and vascular/mixed type dementia were identified as risk factors
for CVAE in association with olanzapine treatment. The efficacy of olanzapine was not established in
these trials.
Parkinson's disease
The use of olanzapine in the treatment of dopamine agonist associated psychosis in patients with
Parkinson's disease is not recommended. In clinical trials, worsening of Parkinsonian symptomatology
and hallucinations were reported very commonly and more frequently than with placebo (see section
4.8), and oral olanzapine was not more effective than placebo in the treatment of psychotic symptoms.
In these trials, patients were initially required to be stable on the lowest effective dose of anti-
Parkinsonian medicinal products (dopamine agonist) and to remain on the same anti-Parkinsonian
medicinal products and dosages throughout the study. Oral olanzapine was started at 2.5 mg/day and
titrated to a maximum of 15 mg/day based on investigator judgement.
Neuroleptic Malignant Syndrome (NMS)
NMS is a potentially life-threatening condition associated with antipsychotic medicinal products. Rare
cases reported as NMS have also been received in association with oral olanzapine. Clinical
manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of
autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac
dysrhythmia). Additional signs may include elevated creatine phosphokinase, myoglobinuria
(rhabdomyolysis), and acute renal failure. If a patient develops signs and symptoms indicative of
NMS, or presents with unexplained high fever without additional clinical manifestations of NMS, all
antipsychotic medicines, including olanzapine must be discontinued.
Hyperglycaemia and diabetes
Hyperglycaemia and/or development or exacerbation of diabetes occasionally associated with
ketoacidosis or coma has been reported rarely, including some fatal cases (see section 4.8). In some
cases, a prior increase in body weight has been reported which may be a predisposing factor.
Appropriate clinical monitoring is advisable in accordance with utilised antipsychotic guidelines.
Patients treated with any antipsychotic agents, including ZYPADHERA, should be observed for signs
and symptoms of hyperglycaemia (such as polydipsia, polyuria, polyphagia, and weakness) and
patients with diabetes mellitus or with risk factors for diabetes mellitus should be monitored regularly
for worsening of glucose control. Weight should be monitored regularly.
Lipid alterations
Undesirable alterations in lipids have been observed in olanzapine-treated patients in placebo-
controlled clinical trials (see section 4.8). Lipid alterations should be managed as clinically
appropriate, particularly in dyslipidemic patients and in patients with risk factors for the development
of lipids disorders. Patients treated with any antipsychotic agents, including ZYPADHERA, should be
monitored regularly for lipids in accordance with utilised antipsychotic guidelines.
Anticholinergic activity
While olanzapine demonstrated anticholinergic activity in vitro , experience during the clinical trials
revealed a low incidence of related events. However, as clinical experience with olanzapine in patients
with concomitant illness is limited, caution is advised when prescribing for patients with prostatic
hypertrophy, or paralytic ileus and related conditions.
41
Hepatic function
Transient, asymptomatic elevations of hepatic aminotransferases, ALT, AST have been seen
commonly, especially in early treatment. Caution should be exercised and follow-up organised in
patients with elevated ALT and/or AST, in patients with signs and symptoms of hepatic impairment,
in patients with pre-existing conditions associated with limited hepatic functional reserve, and in
patients who are being treated with potentially hepatotoxic medicines. In cases where hepatitis
(including hepatocellular, cholestatic or mixed liver injury) has been diagnosed, olanzapine treatment
should be discontinued.
Neutropenia
Caution should be exercised in patients with low leukocyte and/or neutrophil counts for any reason, in
patients receiving medicines known to cause neutropenia, in patients with a history of drug-induced
bone marrow depression/toxicity, in patients with bone marrow depression caused by concomitant
illness, radiation therapy or chemotherapy and in patients with hypereosinophilic conditions or with
myeloproliferative disease. Neutropenia has been reported commonly when olanzapine and valproate
are used concomitantly (see section 4.8).
Discontinuation of treatment
Acute symptoms such as sweating, insomnia, tremor, anxiety, nausea, or vomiting have been reported
very rarely (<0.01%) when oral olanzapine is stopped abruptly.
QT interval
In clinical trials with oral olanzapine, clinically meaningful QTc prolongations (Fridericia QT
correction [QTcF] ≥ 500 milliseconds [msec] at any time post baseline in patients with baseline
QTcF<500 msec) were uncommon (0.1% to 1%) in patients treated with olanzapine, with no
significant differences in associated cardiac events compared to placebo. In clinical trials with
olanzapine powder for solution for injection or ZYPADHERA, olanzapine was not associated with a
persistent increase in absolute QT or in QTc intervals. However, as with other antipsychotics, caution
should be exercised when olanzapine is prescribed with medicines known to increase QTc interval,
especially in the elderly, in patients with congenital long QT syndrome, congestive heart failure, heart
hypertrophy, hypokalaemia or hypomagnesaemia.
Thromboembolism
Temporal association of olanzapine treatment and venous thromboembolism has very rarely (< 0.01%)
been reported. A causal relationship between the occurrence of venous thromboembolism and
treatment with olanzapine has not been established. However, since patients with schizophrenia often
present with acquired risk factors for venous thromboembolism all possible risk factors of VTE e.g.
immobilisation of patients, should be identified and preventive measures undertaken.
General CNS activity
Given the primary CNS effects of olanzapine, caution should be used when it is taken in combination
with other centrally acting medicines and alcohol. As it exhibits in vitro dopamine antagonism,
olanzapine may antagonize the effects of direct and indirect dopamine agonists.
Seizures
Olanzapine should be used cautiously in patients who have a history of seizures or are subject to
factors which may lower the seizure threshold. Seizures have been reported to occur rarely in patients
when treated with olanzapine. In most of these cases, a history of seizures or risk factors for seizures
were reported.
Tardive dyskinesia
In comparator studies of one year or less duration, olanzapine was associated with a statistically
significant lower incidence of treatment emergent dyskinesia. However the risk of tardive dyskinesia
increases with long term exposure, and therefore if signs or symptoms of tardive dyskinesia appear in
a patient on olanzapine, a dose reduction or discontinuation should be considered. These symptoms
can temporally deteriorate or even arise after discontinuation of treatment.
42
Postural hypotension
Postural hypotension was infrequently observed in the elderly in olanzapine clinical trials. As with
other antipsychotics, it is recommended that blood pressure is measured periodically in patients over
65 years.
Sudden cardiac death
In postmarketing reports with olanzapine, the event of sudden cardiac death has been reported in
patients with olanzapine. In a retrospective observational cohort study, the risk of presumed sudden
cardiac death in patients treated with olanzapine was approximately twice the risk in patients not using
antipsychotics. In the study, the risk of olanzapine was comparable to the risk of atypical
antipsychotics included in a pooled analysis.
Paediatric population
Olanzapine is not indicated for use in the treatment of children and adolescents. Studies in patients
aged 13-17 years showed various adverse reactions, including weight gain, changes in metabolic
parameters and increases in prolactin levels. Long-term outcomes associated with these events have
not been studied and remain unknown (see sections 4.8 and 5.1).
Use in elderly patients (>75 years)
No information on the use of ZYPADHERA in patients >75 years is available. Due to biochemical
and physiological modification and reduction of muscular mass, this formulation is not recommended
to be started in this sub-group of patients.
4.5 Interaction with other medicinal products and other forms of interaction
Paediatric population
Interaction studies have only been performed in adults.
Caution should be exercised in patients who receive medicinal products that can induce hypotension or
sedation.
Potential interactions affecting olanzapine
Since olanzapine is metabolised by CYP1A2, substances that can specifically induce or inhibit this
isoenzyme may affect the pharmacokinetics of olanzapine.
Induction of CYP1A2
The metabolism of olanzapine may be induced by smoking and carbamazepine, which may lead to
reduced olanzapine concentrations. Only slight to moderate increase in olanzapine clearance has been
observed. The clinical consequences are likely to be limited, but clinical monitoring is recommended
and an increase of olanzapine dose may be considered if necessary (see section 4.2).
Inhibition of CYP1A2
Fluvoxamine, a specific CYP1A2 inhibitor, has been shown to significantly inhibit the metabolism of
olanzapine. The mean increase in olanzapine C max following fluvoxamine was 54 % in female non-
smokers and 77 % in male smokers. The mean increase in olanzapine AUC was 52 % and 108 %
respectively. A lower starting dose of olanzapine should be considered in patients who are using
fluvoxamine or any other CYP1A2 inhibitors, such as ciprofloxacin. A decrease in the dose of
olanzapine should be considered if treatment with an inhibitor of CYP1A2 is initiated.
Fluoxetine (a CYP2D6 inhibitor), single doses of antacid (aluminium, magnesium) or cimetidine have
not been found to significantly affect the pharmacokinetics of olanzapine.
Potential for olanzapine to affect other medicinal products
Olanzapine may antagonise the effects of direct and indirect dopamine agonists.
Olanzapine does not inhibit the main CYP450 isoenzymes in vitro (e.g. 1A2, 2D6, 2C9, 2C19, 3A4).
Thus no particular interaction is expected as verified through in vivo studies where no inhibition of
43
metabolism of the following active substances was found: tricyclic antidepressant (representing mostly
CYP2D6 pathway), warfarin (CYP2C9), theophylline (CYP1A2) or diazepam (CYP3A4 and 2C19).
Olanzapine showed no interaction when co-administered with lithium or biperiden.
Therapeutic monitoring of valproate plasma levels did not indicate that valproate dosage adjustment is
required after the introduction of concomitant olanzapine.
General CNS activity
Caution should be exercised in patients who consume alcohol or receive medicinal products that can
cause central nervous system depression.
The concomitant use of olanzapine with anti-Parkinsonian medicinal products in patients with
Parkinson's disease and dementia is not recommended (see section 4.4).
QTc interval
Caution should be used if olanzapine is being administered concomitantly with medicinal products
known to increase QTc interval (see section 4.4).
4.6 Fertility, pregnancy and lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women. Patients should be advised to
notify their physician if they become pregnant or intend to become pregnant during treatment with
olanzapine. Nevertheless, because human experience is limited, olanzapine should be used in
pregnancy only if the potential benefit justifies the potential risk to the foetus.
Spontaneous reports have been very rarely received on tremor, hypertonia, lethargy and sleepiness, in
infants born to mothers who had used olanzapine during the 3rd trimester.
Breast feeding
In a study of oral olanzapine in breast feeding, healthy women, olanzapine was excreted in breast
milk. Mean infant exposure (mg/kg) at steady state was estimated to be 1.8% of the maternal
olanzapine dose (mg/kg). Patients should be advised not to breast feed an infant if they are taking
olanzapine.
4.7 Effects on ability to drive and use machines
No studies on the effects on the ability to drive and use machines have been performed. As olanzapine
may cause somnolence and dizziness, patients should be cautioned about operating machinery,
including motor vehicles.
Patients should be advised not to drive or operate machinery for the remainder of the day after each
injection due to the possibility of a post-injection syndrome event leading to symptoms consistent with
olanzapine overdose (see section 4.4).
4.8 Undesirable effects
Post-injection syndrome reactions have occurred with ZYPADHERA leading to symptoms consistent
with olanzapine overdose (see sections 4.2 and 4.4). Clinical signs and symptoms included symptoms
of sedation (ranging from mild in severity up to coma) and/or delirium (including confusion,
disorientation, agitation, anxiety and other cognitive impairment). Other symptoms noted include
extrapyramidal symptoms, dysarthria, ataxia, aggression, dizziness, weakness, hypertension and
convulsion.
Other adverse reactions observed in patients treated with ZYPADHERA were similar to those seen
with oral olanzapine. In clinical trials with ZYPADHERA, the only adverse reaction reported at a
44
statistically significantly higher rate in the ZYPADHERA group than in the placebo group was
sedation (ZYPADHERA 8.2%, placebo 2.0%). Among all ZYPADHERA treated patients, sedation
was reported by 4.7% of patients .
In clinical trials with ZYPADHERA the incidence of injection site related adverse reactions was
approximately 8%. The most commonly reported injection site related adverse reaction was pain (5%);
some other injection site adverse reactions reported were (in decreasing frequency): nodule type
reactions, erythema type reactions, non-specific injection site reactions, irritation, oedema type
reactions, bruising, haemorrhage, and anaesthesia. These events occurred in about 0.1 to 1.1% of
patients.
The undesirable effects listed below have been observed following administration of oral olanzapine
but may occur following administration of ZYPADHERA.
Adults
The most frequently (seen in ≥ 1% of patients ) reported adverse reactions associated with the use of
olanzapine in clinical trials were somnolence, weight gain, eosinophilia, elevated prolactin,
cholesterol, glucose and triglyceride levels (see section 4.4), glucosuria, increased appetite, dizziness,
akathisia, parkinsonism (see section 4.4), dyskinesia, orthostatic hypotension, anticholinergic effects,
transient asymptomatic elevations of hepatic aminotransferases (see section 4.4), rash, asthenia,
fatigue and oedema.
The following table lists the adverse reactions and laboratory investigations observed from
spontaneous reporting and in clinical trials. Within each frequency grouping, adverse reactions are
presented in order of decreasing seriousness. The frequency terms listed are defined as follows: Very
common (≥10%), common (≥ 1% and < 10%), uncommon (≥ 0.1% and < 1%), rare (≥ 0.01% and

1 Clinically significant weight gain was observed across all baseline Body Mass Index (BMI)
categories. Following short term treatment (median duration 47 days), weight gain ≥ 7% of baseline
body weight was very common (22.2 %), ≥ 15 % was common (4.2 %) and ≥ 25 % was uncommon
(0.8 %) Patients gaining ≥ 7 %, ≥ 15 % and ≥ 25% of their baseline body weight with long-term
exposure (at least 48 weeks were very common (64.4 %, 31.7 % and 12.3 % respectively) .
2 Mean increases in fasting lipid values (total cholesterol, LDL cholesterol, and triglycerides) were
greater in patients without evidence of lipid dysregulation at baseline.
46
 
3 Observed for fasting normal levels at baseline (< 5.17 mmol/l) which increased to high
(≥ 6.2 mmol/l). Changes in total fasting cholesterol levels from borderline at baseline (≥ 5.17 -
< 6.2 mmol/l) to high (≥ 6.2 mmol/l) were very common.
4 Observed for fasting normal levels at baseline (< 5.56 mmol/l) which increased to high (≥ 7 mmol/l).
Changes in fasting glucose from borderline at baseline (≥ 5.56 - < 7 mmol/l) to high (≥ 7 mmol/l) were
very common.
5 Observed for fasting normal levels at baseline (< 1.69 mmol/l) which increased to high
(≥ 2.26 mmol/l). Changes in fasting triglycerides from borderline at baseline (≥ 1.69 mmol/l -
< 2.26 mmol/l) to high (≥ 2.26 mmol/l) were very common.
6 In clinical trials, the incidence of Parkinsonism and dystonia in olanzapine-treated patients was
numerically higher, but not statistically significantly different from placebo. Olanzapine-treated
patients had a lower incidence of Parkinsonism, akathisia and dystonia compared with titrated doses of
haloperidol. In the absence of detailed information on the pre-existing history of individual acute and
tardive extrapyramidal movement disorders, it can not be concluded at present that olanzapine
produces less tardive dyskinesia and/or other tardive extrapyramidal syndromes.
7 Acute symptoms such as sweating, insomnia, tremor, anxiety, nausea and vomiting have been
reported when olanzapine is stopped abruptly.
8 In clinical trials of up to 12 weeks, plasma prolactin concentrations exceeded the upper limit of
normal range in approximately 30% of olanzapine treated patients with normal baseline prolactin
value. In the majority of these patients the elevations were generally mild, and remained below two
times the upper limit of normal range. Generally in olanzapine-treated patients potentially associated
breast- and menstrual related clinical manifestations (e.g. amenorrhoea, breast enlargement,
galactorrhea in females, and gynaecomastia/breast enlargement in males) were uncommon. Potentially
associated sexual function-related adverse reactions (e.g. erectile dysfunction in males and decreased
libido in both genders) were commonly observed.
Long-term exposure (at least 48 weeks)
The proportion of patients who had adverse, clinically significant changes in weight gain, glucose,
total/LDL/HDL cholesterol or triglycerides increased over time. In adult patients who completed 9-12
months of therapy, the rate of increase in mean blood glucose slowed after approximately 6 months.
Additional information on special populations
In clinical trials in elderly patients with dementia, olanzapine treatment was associated with a higher
incidence of death and cerebrovascular adverse reactions compared to placebo (see also section 4.4).
Very common adverse reactions associated with the use of olanzapine in this patient group were
abnormal gait and falls. Pneumonia, increased body temperature, lethargy, erythema, visual
hallucinations and urinary incontinence were observed commonly.
In clinical trials in patients with drug-induced (dopamine agonist) psychosis associated with
Parkinson’s disease, worsening of Parkinsonian symptomatology and hallucinations were reported
very commonly and more frequently than with placebo.
In one clinical trial in patients with bipolar mania, valproate combination therapy with olanzapine
resulted in an incidence of neutropenia of 4.1%; a potential contributing factor could be high plasma
valproate levels. Olanzapine administered with lithium or valproate resulted in increased levels
(≥10%) of tremor, dry mouth, increased appetite, and weight gain. Speech disorder was also reported
commonly. During treatment with olanzapine in combination with lithium or divalproex, an increase
of ≥ 7% from baseline body weight occurred in 17.4% of patients during acute treatment (up to 6
weeks). Long-term olanzapine treatment (up to 12 months) for recurrence prevention in patients with
bipolar disorder was associated with an increase of ≥7% from baseline body weight in 39.9% of
patients.
47
Paediatric population
Olanzapine is not indicated for the treatment of children and adolescent patients below 18 years.
Although no clinical studies designed to compare adolescents to adults have been conducted, data
from the adolescent trials were compared to those of the adult trials.
The following table summarises the adverse reactions reported with a greater frequency in adolescent
patients (aged 13-17 years) than in adult patients or adverse reactions only identified during short-term
clinical trials in adolescent patients. Clinically significant weight gain (≥ 7%) appears to occur more
frequently in the adolescent population compared to adults with comparable exposures. The magnitude
of weight gain and the proportion of adolescent patients who had clinically significant weight gain
were greater with long-term exposure (at least 24 weeks) than with short-term exposure.
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.
The frequency terms listed are defined as follows: Very common (≥ 10%), common (≥ 1% and
< 10%).
Metabolism and nutrition disorders
Very common: Weight gain 9 , elevated triglyceride levels 10 , increased appetite.
Common: Elevated cholesterol levels 11
Nervous system disorders
Very common: Sedation (including: hypersomnia, lethargy, somnolence).
Gastrointestinal disorders
Common: Dry mouth
Hepato-biliary disorders
Very common: Elevations of hepatic aminotransferases (ALT/AST; see section 4.4).
Investigations
Very common: Decreased total bilirubin, increased GGT, elevated plasma prolactin levels 12 .
9 Following short term treatment (median duration 22 days), weight gain ≥ 7% of baseline body weight
(kg) was very common (40.6 %), ≥ 15% of baseline body weight was common (7.1 %) and ≥ 25 %
was common (2.5 %). With long-term exposure (at least 24 weeks), 89.4 % gained ≥ 7 %, 55.3 %
gained ≥ 15 % and 29.1 % gained ≥ 25% of their baseline body weight.
10 Observed for fasting normal levels at baseline (< 1.016 mmol/l) which increased to high
(≥ 1.467 mmol/l) and changes in fasting triglycerides from borderline at baseline (≥ 1.016 mmol/l -
< 1.467 mmol/l) to high (≥ 1.467 mmol/l).
11 Changes in total fasting cholesterol levels from normal at baseline (< 4.39 mmol/l) to high
(≥ 5.17 mmol/l) were observed commonly. Changes in total fasting cholesterol levels from borderline
at baseline (≥ 4.39 - < 5.17 mmol/l) to high (≥ 5.17 mmol/l) were very common.
12 Elevated plasma prolactin levels were reported in 47.4% of adolescent patients.
4.9 Overdose
If signs and symptoms of overdose consistent with post injection syndrome are observed, appropriate
supportive measures should be taken (see section 4.4).
While overdose is less likely with parenteral than oral medicinal products, reference information for
oral olanzapine overdose is presented below:
Signs and symptoms
Very common symptoms in overdose (>10% incidence) include tachycardia, agitation/aggressiveness,
dysarthria, various extrapyramidal symptoms, and reduced level of consciousness ranging from
sedation to coma.
48
 
Other medically significant sequelae of overdose include delirium, convulsion, coma, possible
neuroleptic malignant syndrome, respiratory depression, aspiration, hypertension or hypotension,
cardiac arrhythmias (< 2% of overdose cases) and cardiopulmonary arrest. Fatal outcomes have been
reported for acute oral overdoses as low as 450 mg but survival has also been reported following acute
overdose of approximately 2 g of oral olanzapine.
Management of overdose
There is no specific antidote for olanzapine. Symptomatic treatment and monitoring of vital organ
function should be instituted according to clinical presentation, including treatment of hypotension and
circulatory collapse and support of respiratory function. Do not use epinephrine, dopamine, or other
sympathomimetic agents with beta-agonist activity since beta stimulation may worsen hypotension.
Cardiovascular monitoring is necessary to detect possible arrhythmias. Close medical supervision and
monitoring should continue until the patient recovers.
5.
PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: diazepines, oxazepines and thiazepines, ATC code N05AH03.
Olanzapine is an antipsychotic, antimanic and mood stabilising agent that demonstrates a broad
pharmacologic profile across a number of receptor systems.
In preclinical studies, olanzapine exhibited a range of receptor affinities (K i ; < 100 nM) for serotonin
5-HT 2A/2C , 5-HT 3 , 5-HT 6 ; dopamine D 1 , D 2 , D 3 , D 4 , D 5 ; cholinergic muscarinic receptors M 1 -M 5 ; α- 1
adrenergic; and histamine H 1 receptors. Animal behavioural studies with olanzapine indicated 5HT,
dopamine, and cholinergic antagonism, consistent with the receptor-binding profile. Olanzapine
demonstrated a greater in vitro affinity for serotonin 5-HT 2 than dopamine D 2 receptors and greater 5-
HT 2 than D 2 activity in viv o, models. Electrophysiological studies demonstrated that olanzapine
selectively reduced the firing of mesolimbic (A10) dopaminergic neurons, while having little effect on
the striatal (A9) pathways involved in motor function. Olanzapine reduced a conditioned avoidance
response, a test indicative of antipsychotic activity, at doses below those producing catalepsy, an effect
indicative of motor side-effects. Unlike some other antipsychotic agents, olanzapine increases
responding in an “anxiolytic” test.
The effectiveness of ZYPADHERA in the treatment and maintenance treatment of schizophrenia is
consistent with the established effectiveness of the oral formulation of olanzapine.
In a Positron Emission Tomography (PET) study in patients treated with ZYPADHERA
(300 mg/4 weeks), mean D 2 receptor occupancy was 60% or higher at the end of a 6 month period, a
level consistent with that found during treatment with oral olanzapine.
A total of 1469 patients with schizophrenia were included in 2 pivotal trials:
The first, an 8-week, placebo controlled trial conducted in adult patients (n=404) who were
experiencing acute psychotic symptoms. Patients were randomized to receive injections of
ZYPADHERA 405 mg every 4 weeks, 300 mg every 2 weeks, 210 mg every 2 weeks, or placebo
every 2 weeks. No oral antipsychotic supplementation was allowed. Total Positive and Negative
Symptom Scores (PANSS) showed significant improvement from baseline (baseline mean Total
PANSS Score 101) to endpoint (mean changes -22.57, -26.32, -22.49 respectively) with each dose of
ZYPADHERA (405 mg every 4 weeks, 300 mg every 2 weeks, and 210 mg every 2 weeks) as
compared to placebo (mean change -8.51). Visitwise mean change from baseline to endpoint in
PANSS Total score indicated that by Day 3, patients in the 300 mg/2 weeks and 405 mg/4 weeks
treatment groups had statistically significantly greater reductions in PANSS Total score compared to
placebo (-8.6, -8.2, and -5.2, respectively). All 3 ZYPADHERA treatment groups showed statistically
significantly greater improvement than placebo beginning by end of Week 1. These results support
49
efficacy for ZYPADHERA over 8 weeks of treatment and a drug effect that was observed as early as
1 week after starting treatment with ZYPADHERA.
The second, a long term study in clinically stable patients (n=1065) (baseline mean Total PANSS
Score 54.33 to 57.75) who were initially treated with oral olanzapine for 4 to 8 weeks and then
switched to continue on oral olanzapine or to ZYPADHERA for 24 weeks. No oral antipsychotic
supplementation was allowed. ZYPADHERA treatment groups of 150 mg and 300 mg given every 2
weeks (doses pooled for analysis) and 405 mg given every 4 weeks were non inferior to the combined
doses of 10, 15 and 20 mg of oral olanzapine (doses pooled for analysis) as measured by rates of
exacerbation of symptoms of schizophrenia (respective exacerbation rates, 10%, 10% 7%).
Exacerbation was measured by worsening of items on the PANSS derived BPRS Positive scale and
hospitalization due to worsening of positive psychotic symptoms. The combined 150 mg and
300 mg/2 week treatment group was non inferior to the 405 mg/4 week treatment group (exacerbation
rates 10% for each group) at 24 weeks after randomisation.
Paediatric population
ZYPADHERA has not been studied in the paediatric population . The experience in adolescents (ages
13 to 17 years) is limited to short term oral olanzapine efficacy data in schizophrenia (6 weeks) and
mania associated with bipolar I disorder (3 weeks), involving less than 200 adolescents. Oral
olanzapine was used as a flexible dose starting with 2.5 and ranging up to 20 mg/day. During
treatment with oral olanzapine, adolescents gained significantly more weight compared with adults.
The magnitude of changes in fasting total cholesterol, LDL cholesterol, triglycerides, and prolactin
(see sections 4.4 and 4.8) were greater in adolescents than in adults. There are no data on maintenance
of effect and limited data on long term safety (see sections 4.4 and 4.8) .
5.2 Pharmacokinetic properties
Olanzapine is metabolised in the liver by conjugative and oxidative pathways. The major circulating
metabolite is the 10-N-glucuronide. Cytochromes P450-CYP1A2 and P450-CYP2D6 contribute to the
formation of the N-desmethyl and 2-hydroxymethyl metabolites; both exhibited significantly less in
vivo pharmacological activity than olanzapine in animal studies. The predominant pharmacologic
activity is from the parent, olanzapine.
After a single IM injection with ZYPADHERA the slow dissolution of the olanzapine pamoate salt in
muscle tissue begins immediately and provides a slow continuous release of olanzapine for more than
four weeks. The release becomes diminishingly smaller within eight to twelve weeks. Antipsychotic
supplementation is not required at the initiation of ZYPADHERA treatment (see section 4.2).
The combination of the release profile and the dosage regimen (IM injection every two or four weeks)
result in sustained olanzapine plasma concentrations. Plasma concentrations remain measurable for
several months after each ZYPADHERA injection. The half-life of olanzapine after ZYPADHERA is
30 days compared to 30 hours following oral administration. The absorption and elimination are
complete approximately six to eight months after the last injection.
Oral olanzapine is rapidly distributed. The plasma protein binding of olanzapine is about 93% over the
concentration range of 7 to about 1000 ng/mL. In plasma, olanzapine is bound to albumin and α1-acid
glycoprotein.
Olanzapine plasma clearance after oral olanzapine is lower in females (18.9 l/hr) versus males
(27.3 l/hr), and in non-smokers (18.6 l/hr) versus smokers (27.7 l/hr). Similar pharmacokinetic
differences between males and females and smokers and nonsmokers were observed in ZYPADHERA
clinical trials. However, the magnitude of the impact of gender, or smoking on olanzapine clearance is
small in comparison to the overall variability between individuals.
After repeated IM injections with 150 to 300 mg ZYPADHERA every two weeks, the 10 th to 90 th
percentile of steady-state plasma concentrations of olanzapine were between 4.2 and 73.2 ng/ml. The
plasma concentrations of olanzapine observed across the dose range of 150mg every 4 weeks to
50
300mg every 2 weeks illustrate increased systemic olanzapine exposure with increased ZYPADHERA
doses. During the initial three months of treatment with ZYPADHERA, accumulation of olanzapine
was observed but there was no additional accumulation during long-term use (12 months) in patients
who were injected with up to 300 mg every two weeks.
No specific investigations have been conducted in the elderly with ZYPADHERA. ZYPADHERA is
not recommended for treatment in the elderly population (65 years and over) unless a well-tolerated
and effective dosage regimen using oral olanzapine has been established. In healthy elderly (65 and
over) versus non-elderly subjects, the mean elimination half-life was prolonged (51.8 versus
33.8 hours) and the clearance was reduced (17.5 versus 18.2 l/hr). The pharmacokinetic variability
observed in the elderly is within the range for the non-elderly. In 44 patients with schizophrenia >65
years of age, dosing from 5 to 20 mg/day was not associated with any distinguishing profile of adverse
events.
In renally impaired patients (creatinine clearance < 10 ml/min) versus healthy subjects, there was no
significant difference in mean elimination half-life (37.7 versus 32.4 hours) or clearance (21.2 versus
25.0 l/hr). A mass balance study showed that approximately 57% of radiolabelled olanzapine appeared
in urine, principally as metabolites. Although patients with renal impairment were not studied with
ZYPADHERA, it is recommended that a well-tolerated and effective dosage regimen using oral
olanzapine is established in patients with renal impairment before treatment with ZYPADHERA is
initiated (see section 4.2).
In smoking subjects with mild hepatic dysfunction, mean elimination half-life (39.3 hours) of orally
administered olanzapine was prolonged and clearance (18.0 l/hr) was reduced analogous to non-
smoking healthy subjects (48.8 hours and 14.1 l/hr, respectively). Although patients with hepatic
impairment were not studied with ZYPADHERA, it is recommended that a well-tolerated and
effective dosage regimen using oral olanzapine is established in patients with hepatic impairment
before treatment with ZYPADHERA is initiated (see section 4.2).
In a study of oral olanzapine given to Caucasians, Japanese, and Chinese subjects, there were no
differences in the pharmacokinetic parameters among the three populations.
5.3 Preclinical safety data
Preclinical safety studies were performed using olanzapine pamoate monohydrate. The main findings
found in repeat-dose toxicity studies (rat, dog), in a 2-year rat carcinogenicity study, and in toxicity to
reproduction studies (rat, rabbit) were limited to injection site reactions for which no NOAEL could be
determined. No new toxic effect resulting from systemic exposure to olanzapine could be identified.
However, systemic concentrations in these studies were generally less than that seen at effect levels in
the oral studies; thus the information on oral olanzapine is provided below for reference.
Acute (single-dose) toxicity
Signs of oral toxicity in rodents were characteristic of potent antipsychotic compounds: hypoactivity,
coma, tremors, clonic convulsions, salivation, and depressed weight gain. The median lethal doses
were approximately 210 mg/kg (mice) and 175 mg/kg (rats). Dogs tolerated single oral doses up to
100 mg/kg without mortality. Clinical signs included sedation, ataxia, tremors, increased heart rate,
laboured respiration, miosis, and anorexia. In monkeys, single oral doses up to 100 mg/kg resulted in
prostration and, at higher doses, semi-consciousness.
Repeated-dose toxicity
In studies up to 3 months duration in mice and up to 1 year in rats and dogs, the predominant effects
were CNS depression, anticholinergic effects, and peripheral haematological disorders. Tolerance
developed to the CNS depression. Growth parameters were decreased at high doses. Reversible effects
consistent with elevated prolactin in rats included decreased weights of ovaries and uterus and
morphologic changes in vaginal epithelium and in mammary gland.
51
Haematologic toxicity: Effects on haematology parameters were found in each species, including
dose-related reductions in circulating leukocytes in mice and non-specific reductions of circulating
leukocytes in rats; however, no evidence of bone marrow cytotoxicity was found. Reversible
neutropenia, thrombocytopenia, or anaemia developed in a few dogs treated with 8 or 10 mg/kg/day
(total olanzapine exposure [AUC] is 12- to 15-fold greater than that of a man given a 12 mg dose). In
cytopenic dogs, there were no undesirable effects on progenitor and proliferating cells in the bone
marrow.
Reproductive toxicity
Olanzapine had no teratogenic effects. Sedation affected mating performance of male rats. Oestrous
cycles were affected at doses of 1.1 mg/kg (3 times the maximum human dose) and reproduction
parameters were influenced in rats given 3 mg/kg (9 times the maximum human dose). In the offspring
of rats given olanzapine, delays in foetal development and transient decreases in offspring activity
levels were seen.
Mutagenicity
Olanzapine was not mutagenic or clastogenic in a full range of standard tests, which included bacterial
mutation tests and in vitro and oral in vivo mammalian tests.
Carcinogenicity
Based on the results of oral studies in mice and rats, it was concluded that olanzapine is not
carcinogenic.

It is important to note that there is more solvent in the vial than is needed to reconstitute.
STEP 3: Reconstituting ZYPADHERA
1. Loosen the powder by lightly tapping the vial.
2. Open the pre-packaged Hypodermic Needle-Pro syringe and needle with needle protection device.
Peel blister pouch and remove device. Insure needle is firmly seated on the Needle-Pro device
with a push and a clockwise twist, then pull the needle cap straight away from the needle. Failure
to follow these instructions may result in a needlestick injury.
3. Withdraw the pre-determined solvent volume (Step 2) into the syringe.
4. Inject the solvent volume into the powder vial.
5. Withdraw air to equalize the pressure in the vial.
6. Remove the needle, holding the vial upright to prevent any loss of solvent.
7. Engage the needle safety device. Press the needle into the sheath using a one-handed technique.
Perform a one-handed technique by GENTLY pressing the sheath against a flat surface. AS THE
SHEATH IS PRESSED, THE NEEDLE IS FIRMLY ENGAGED INTO THE SHEATH (Figure 1
and 2)
8. Visually confirm that the needle is fully engaged into the needle protection sheath. (Figure 3) Only
remove the Needle-Pro device with the engaged needle from the syringe when required by a
specific medical procedure. Remove by grasping the Luer hub of the needle protection device with
53
 
thumb and forefinger, keeping the free fingers clear of the end of the device containing the needle
point.
Figure 1
Figure 2
Figure 3
9. Tap the vial firmly and repeatedly on a hard surface until no powder is visible. Protect the surface
to cushion impact. (See Figure A)
Figure A: Tap firmly to mix
10. Visually check the vial for clumps. Unsuspended powder appears as yellow, dry clumps clinging
to the vial. Additional tapping may be required if clumps remain. (See Figure B)
Unsuspended: visible clumps Suspended: no clumps
Figure B: Check for unsuspended powder and repeat tapping if needed .
11. Shake the vial vigorously until the suspension appears smooth and is consistent in color and
texture. The suspended product will be yellow and opaque. (See Figure C)
Figure C: Vigorously shake vial
If foam forms, let vial stand to allow foam to dissipate. If the product is not used immediately, it
should be shaken vigorously to re-suspend. Reconstituted ZYPADHERA remains stable for up to
24 hours in the vial.

1. Determine which needle will be used to administer the injection to the patient. For obese patients,
the 50 mm needle is recommended for injection:
If the 50 mm needle is to be used for injection, attach the 38 mm safety needle to the syringe to
withdraw the required suspension volume.
If the 38 mm needle is to be used for the injection, attach the 50 mm safety needle to withdraw
the required suspension volume
2. Slowly withdraw the desired amount. Some excess product will remain in the vial.
3. Engage the needle safety device and remove needle from syringe.
4. Attach the remaining safety needle to the syringe prior to injection. Once the suspension has been
removed from the vial, it should be injected immediately.
5. Select and prepare a site for injection in the gluteal area. DO NOT INJECT INTRAVENOUSLY
OR SUBCUTANEOUSLY.
6. After insertion of the needle, aspirate for several seconds to ensure no blood appears. If any blood
is drawn into the syringe, discard the syringe and the dose and begin reconstitution and
administration procedure again. The injection should be performed with steady, continuous
pressure.
DO NOT MASSAGE THE INJECTION SITE.
7. Engage the needle safety device. (Figure 1 and 2)
8. Discard the vials, syringe, needles and any unused solvent in accordance with appropriate clinical
procedures. The vial is for single use only.

1.
WHAT ZYPADHERA IS AND WHAT IT IS USED FOR
ZYPADHERA belongs to a group of medicines called antipsychotics and is used to treat
schizophrenia - a disease with symptoms such as hearing, seeing or sensing things which are not there,
mistaken beliefs, unusual suspiciousness, and becoming withdrawn. People with this disease may also
feel depressed, anxious or tense.
2.
BEFORE YOU ARE GIVEN ZYPADHERA
You should not be given ZYPADHERA if you have:
an allergy (hypersensitivity) to olanzapine or any of the other ingredients of ZYPADHERA. An
allergic reaction may be recognised as a rash, itching, a swollen face, swollen lips or shortness of
breath. If this has happened to you, tell your nurse or doctor.
been previously diagnosed with eye problems such as certain kinds of glaucoma (increased pressure
in the eye).
Take special care with ZYPADHERA
Prior to giving ZYPADHERA, your doctor or nurse should determine that you will not travel
alone to your destination after each injection.
An uncommon but serious reaction might occur after you receive each injection. ZYPADHERA
can sometimes enter the bloodstream too quickly. If this happens, you may have the symptoms
listed below after your injection. In some cases, these symptoms can lead to unconsciousness.
excessive sleepiness
dizziness
confusion
disorientation
irritability
anxiety
aggression
increase in blood pressure
72
difficulty talking
weakness
difficulty walking
muscle stiffness or shaking
convulsions
These symptoms typically resolve within 24 to 72 hours after your injection. After each injection
you will be observed in your healthcare facility for at least 3 hours for the symptoms listed above.
Although unlikely, you may get the symptoms more than 3 hours after the injection. If this
happens, contact your doctor or nurse immediately. Because of this risk, do not drive or operate
machinery for the remainder of the day after each injection.
Tell the doctor or nurse if you feel dizzy or faint after the injection. You will probably need to lie
down until you feel better. The doctor or nurse may also want to measure your blood pressure and
pulse.
Very rarely, medicines of this type may cause unusual movements mainly of the face or tongue or a
combination of fever, faster breathing, sweating, muscle stiffness and drowsiness or sleepiness. If
this happens after you have been given ZYPADHERA, tell your doctor or nurse immediately.
The use of ZYPADHERA in elderly patients with dementia is not recommended as it may have
serious side effects.
Tell your doctor as soon as possible if any of the following applies to you:
a recent heart attack, heart disease, sick sinus syndrome, (abnormal heart rhythms),
unstable angina or low blood pressure
diabetes
liver or kidney disease
Parkinson’s disease
epilepsy
prostate problems
a blocked intestine (paralytic ileus)
blood disorders
stroke or “mini” stroke (temporary symptoms of stroke)
ZYPADHERA is not for patients who are under 18 years.
As a routine precaution, if you are over 65 years your doctor may monitor your blood pressure.
Taking other medicines
Please tell your doctor if you are taking or have recently taken any other medicines, including those
obtained without a prescription.
In particular, tell your doctor if you are taking:
medicines for Parkinson’s disease.
fluvoxamine (an antidepressant) or ciprofloxacin (an antibiotic) - it may be necessary to change
your ZYPADHERA dose.
If you are already taking antidepressants, medicines for anxiety or to help you sleep (tranquillisers),
you may feel drowsy if ZYPADHERA is given.
Using ZYPADHERA with food and drink
Do not drink any alcohol if you have been given ZYPADHERA as together with alcohol it may make
you feel drowsy.
Pregnancy and breast-feeding
Tell your doctor as soon as possible if you are pregnant or think you may be pregnant.
73
You should not be given this injection if you are breast-feeding as small amounts of
olanzapine can pass into breast milk.
Driving and using machines
Do not drive or operate machinery for the remainder of the day after each injection.
3.
HOW ZYPADHERA IS GIVEN
Your doctor will decide how much ZYPADHERA you need and how often you need to be given an
injection. ZYPADHERA is given in doses of 150 to 300 mg every 2 weeks or 300 to 405 mg every 4
weeks.
ZYPADHERA comes as a powder which your doctor or nurse will make into a suspension that will
then be injected into the muscle in your buttock.
If you are given more ZYPADHERA than needed
This medicine will be given to you under medical supervision, it is therefore unlikely that you will be
given too much.
Patients who have been given too much olanzapine have also experienced the following symptoms:
rapid beating of the heart, agitation/aggressiveness, problems with speech, unusual movements
(especially of the face or tongue) and reduced level of consciousness.
Other symptoms may include:
acute confusion, seizures (epilepsy), coma, a combination of fever, faster breathing, sweating,

Vial of ZYPADHERA powder for prolonged release suspension for injection
Vial of solvent for ZYPADHERA
One Hypodermic Needle-Pro syringe and safety needle (Hypodermic Needle-Pro Device)
One 19-gauge, 38 mm Hypodermic Needle-Pro safety needle
One 19-gauge, 50 mm Hypodermic Needle-Pro safety needle
Patient Information Leaflet
Reconstitution and Administration card (this leaflet)
Hypodermic Needle-Pro Device Safety Information and Instructions for Use leaflet
It is recommended that gloves are used as ZYPADHERA may irritate the skin.
Reconstitute ZYPADHERA powder for prolonged release suspension for injection only with the

products.
STEP 2: Determining solvent volume for reconstitution
This table provides the amount of solvent required to reconstitute ZYPADHERA powder for
prolonged release suspension for injection.

It is important to note that there is more solvent in the vial than is needed to reconstitute.
STEP 3: Reconstituting ZYPADHERA
1. Loosen the powder by lightly tapping the vial.
79
 
2. Open the pre-packaged Hypodermic Needle-Pro syringe and needle with needle protection device.
Peel blister pouch and remove device. Insure needle is firmly seated on the Needle-Pro device
with a push and a clockwise twist, then pull the needle cap straight away from the needle. Failure
to follow these instructions may result in a needle stick injury.
3. Withdraw the pre-determined solvent volume (Step 2) into the syringe.
4. Inject the solvent volume into the powder vial.
5. Withdraw air to equalize the pressure in the vial.
6. Remove the needle, holding the vial upright to prevent any loss of solvent.
7. Engage the needle safety device. Press the needle into the sheath using a one-handed technique.
Perform a one-handed technique by GENTLY pressing the sheath against a flat surface. AS THE
SHEATH IS PRESSED, THE NEEDLE IS FIRMLY ENGAGED INTO THE SHEATH (Figure 1
and 2)
8. Visually confirm that the needle is fully engaged into the needle protection sheath. (Figure 3) Only
remove the Needle-Pro device with the engaged needle from the syringe when required by a
specific medical procedure. Remove by grasping the Luer hub of the needle protection device with
thumb and forefinger, keeping the free fingers clear of the end of the device containing the needle
point.
Figure 1 Figure 2 Figure 3
9. Tap the vial firmly and repeatedly on a hard surface until no powder is visible. Protect the surface
to cushion impact. (See Figure A)
Figure A: Tap firmly to mix
10. Visually check the vial for clumps. Unsuspended powder appears as yellow, dry clumps clinging
to the vial. Additional tapping may be required if clumps remain. (See Figure B)
Unsuspended: visible clumps Suspended: no clumps
Figure B: Check for unsuspended powder and repeat tapping if needed .
11. Shake the vial vigorously until the suspension appears smooth and is consistent in color and
texture. The suspended product will be yellow and opaque. (See Figure C)
Figure C: Vigorously shake vial
80
If foam forms, let vial stand to allow foam to dissipate. If the product is not used immediately, it
should be shaken vigorously to re-suspend. Reconstituted ZYPADHERA remains stable for up to
24 hours in the vial.
Administration
STEP 1: Injecting ZYPADHERA
This table confirms the final ZYPADHERA suspension volume to inject. Suspension concentration is
150 mg/ml olanzapine.

1. Determine which needle will be used to administer the injection to the patient. For obese patients,
the 50 mm needle is recommended for injection:
If the 50 mm needle is to be used for injection, attach the 38 mm safety needle to the syringe to
withdraw the required suspension volume.
If the 38 mm needle is to be used for the injection, attach the 50 mm safety needle to withdraw
the required suspension volume.
2. Slowly withdraw the desired amount. Some excess product will remain in the vial.
3. Engage the needle safety device and remove needle from syringe.
4. Attach the remaining safety needle to the syringe prior to injection. Once the suspension has been
removed from the vial, it should be injected immediately.
5. Select and prepare a site for injection in the gluteal area. DO NOT INJECT INTRAVENOUSLY
OR SUBCUTANEOUSLY.
6. After insertion of the needle, aspirate for several seconds to ensure no blood appears. If any blood
is drawn into the syringe, discard the syringe and the dose and begin reconstitution and
administration procedure again. The injection should be performed with steady, continuous
pressure.
DO NOT MASSAGE THE INJECTION SITE.
7. Engage the needle safety device. (Figure 1 and 2)
8. Discard the vials, syringe, needles and any unused solvent in accordance with appropriate clinical
procedures. The vial is for single use only.
