Summary for the public


What is Osseor?

Osseor is a medicine that contains the active substance strontium ranelate. It is available as 2-g sachets containing granules that are made up into an oral suspension.


What is Osseor used for?

Osseor is used to treat osteoporosis (a disease that makes bones fragile) in women who have been through the menopause, to reduce the risk of broken bones in the spine and the hip.

The medicine can only be obtained with a prescription.


How is Osseor used?

Osseor is taken as one sachet once a day. The contents of the sachet are mixed into a glass of water to form a suspension and drunk just after being prepared. Osseor should be taken at least two hours after food, milk, milk products or calcium supplements, preferably at bedtime. Osseor is intended for long-term use. Patients should receive calcium or vitamin D supplements if they are not getting enough from their diet.


How does Osseor work?

Osteoporosis happens when not enough new bone grows to replace the bone that is naturally broken down. Gradually, the bones become thin and fragile, and more likely to break. Osteoporosis is more common in women after the menopause, when the levels of the female hormone oestrogen fall, since oestrogen helps to keep bones healthy.

The active substance in Osseor, strontium ranelate, acts on the bone structure. Once in the gut, strontium ranelate releases strontium, which is absorbed into the bone. Exactly how strontium works in osteoporosis is not fully understood, but it is known to stimulate bone formation and reduce bone breakdown.


How has Osseor been studied?

Osseor has been studied in almost 7,000 elderly women in two large studies. Nearly a quarter of the patients were over 80 years of age. The first study included 1,649 women with osteoporosis who had already had a broken bone in the spine and the second included over 5,000 women whose osteoporosis was affecting the hip region in the thighbone. In both studies, Osseor was compared with placebo (a dummy treatment) and the main measure of effectiveness was the reduction in the risk of a new bone break with Osseor. In the first study, this was based on the number of patients who, over three years, developed a new break in the spine, and in the second study, it was based on the number of patients who had a new break due to osteoporosis at any site other than the spine.


What benefit has Osseor shown during the studies?

In the first study, Osseor reduced the risk of new breaks in the spine by 41% over three years: 21% of the 719 women who took Osseor developed a new break in the spine, compared with 33% of the 723 who took placebo.

Overall, the results of the second study taken alone were insufficient to demonstrate a benefit of Osseor in preventing bone breaks. However, when looking only at women of 74 years of age or older with particularly weak thighbones, the results suggested a reduction of the risk of breaks in the hip with Osseor.

When looking at results of the two studies taken together, fewer women in the Osseor group developed breaks at any site outside the spine (including the hip) than in the placebo group (331 out of 3,295 with Osseor compared with 389 out of 3,256 for placebo). This showed that the risk of broken bones is reduced.


What is the risk associated with Osseor?

The most common side effects with Osseor (seen in between 1 and 10 patients in 100) are headache, disturbances in consciousness (fainting), memory loss, nausea (feeling sick), diarrhoea, loose stools, dermatitis (inflammation of the skin), eczema (flaky skin rash), venous thromboembolism (blood clots in the veins) and increased blood creatinine kinase levels (an enzyme found in muscle). For the full list of all side effects reported with Osseor, see the Package Leaflet.

Osseor should not be used in people who may be hypersensitive (allergic) to strontium ranelate or any of the other ingredients.


Why has Osseor been approved?

The Committee for Medicinal Products for Human Use (CHMP) decided that Osseor’s benefits are greater than its risks for the treatment of osteoporosis in postmenopausal women to reduce the risk of vertebral and hip fractures. The Committee recommended that Osseor be given marketing authorisation.

SUMMARY OF PRODUCT CHARACTERISTICS


1.
NAME OF THE MEDICINAL PRODUCT
OSSEOR 2 g granules for oral suspension
2.
QUALITATIVE AND QUANTITATIVE COMPOSITION
Each sachet contains 2 g of strontium ranelate.
Excipient: Each sachet also contains 20 mg of aspartame (E951).
For a full list of excipients, see section 6.1.
3.
PHARMACEUTICAL FORM
Granules for oral suspension
Yellow granules
4.
CLINICAL PARTICULARS
4.1 Therapeutic indications
Treatment of osteoporosis in postmenopausal women to reduce the risk of vertebral and hip fractures
(see section 5.1).
4.2 Posology and method of administration
Posology
The recommended dose is one 2 g sachet once daily by oral administration.
Due to the nature of the treated disease, strontium ranelate is intended for long-term use.
The absorption of strontium ranelate is reduced by food, milk and derivative products and therefore,
OSSEOR should be administered in-between meals. Given the slow absorption, OSSEOR should be
taken at bedtime, preferably at least two hours after eating (see sections 4.5 and 5.2).
Patients treated with strontium ranelate should receive vitamin D and calcium supplements if dietary
intake is inadequate.
Elderly population
The efficacy and safety of strontium ranelate have been established in a broad age range (up to
100 years at inclusion) of postmenopausal women with osteoporosis. No dose adjustment is required
in relation to age.
Renal impairment
Strontium ranelate is not recommended for patients with severe renal impairment (creatinine clearance
below 30 ml/min) (see sections 4.4 and 5.2). No dose adjustment is required in patients with mild-to-
moderate renal impairment (30-70 ml/min creatinine clearance) (see section 5.2).
2
Hepatic impairment
As strontium ranelate is not metabolised, no dose adjustment is required in patients with hepatic
impairment.
Paediatric population
The safety and efficacy of OSSEOR in children aged below 18 years have not been established. No
data are available.
Method of administration
For oral use.
The granules in the sachets must be taken as a suspension in a glass containing a minimum of 30 ml
(approximately one third of a standard glass) of water.
Although in-use studies have demonstrated that strontium ranelate is stable in suspension for 24 hours
after preparation, the suspension should be drunk immediately after being prepared.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients.
4.4 Special warnings and precautions for use
Use in patients with renal impairment
In the absence of bone safety data in patients with severe renal impairment treated with strontium
ranelate, OSSEOR is not recommended in patients with a creatinine clearance below 30 ml/min (see
section 5.2). In accordance with good medical practice, periodic assessment of renal function is
recommended in patients with chronic renal impairment. Continuation of treatment with OSSEOR in
patients developing severe renal impairment should be considered on an individual basis.
Venous thromboembolism
In phase III placebo-controlled studies, strontium ranelate treatment was associated with an increase in
the annual incidence of venous thromboembolism (VTE), including pulmonary embolism (see section
4.8). The cause of this finding is unknown. OSSEOR should be used with caution in patients at
increased risk of VTE, including patients with a past history of VTE. When treating patients at risk, or
developing risk of VTE, particular attention should be given to possible signs and symptoms of VTE
and adequate preventive measures taken.
Skin reactions
Cases of severe hypersensitivity syndromes, including, in particular, drug rash with eosinophilia and
systemic symptoms (DRESS), sometimes fatal, have been reported with the use of OSSEOR (see
section 4.8). The DRESS syndrome is characterised by rash, fever, eosinophilia and systemic
involvement (e.g. adenopathy, hepatitis, interstitial nephropathy, interstitial lung disease). Time to
onset was usually around 3-6 weeks and the outcome in most cases favourable upon discontinuation of
OSSEOR and after initiation of corticosteroid therapy. Recovery could be slow and recurrences of the
syndrome have been reported in some cases after discontinuation of corticosteroid therapy.
Patients should be informed to stop OSSEOR immediately and permanently when a rash occurs and to
seek medical advice. Patients who have stopped treatment due to hypersensitivity reactions or other
serious allergic reactions should not re-start therapy with OSSEOR.
Interaction with laboratory test
Strontium interferes with colorimetric methods for the determination of blood and urinary calcium
concentrations. Therefore, in medical practice, inductively coupled plasma atomic emission
spectrometry or atomic absorption spectrometry methods should be used to ensure an accurate
assessment of blood and urinary calcium concentrations.
3
Excipient
OSSEOR contains a source of phenylalanine, which may be harmful for people with phenylketonuria.
4.5 Interaction with other medicinal products and other forms of interaction
Food, milk and derivative products, and medicinal products containing calcium may reduce the
bioavailability of strontium ranelate by approximately 60-70%. Therefore, administration of OSSEOR
and such products should be separated by at least two hours (see section 5.2).
As divalent cations can form complexes with oral tetracycline and quinolone antibiotics at the gastro-
intestinal level and thereby reduce their absorption, simultaneous administration of strontium ranelate
with these medicinal products is not recommended. As a precautionary measure, OSSEOR treatment
should be suspended during treatment with oral tetracycline or quinolone antibiotics.
An in vivo clinical interaction study showed that the administration of aluminium and magnesium
hydroxides either two hours before or together with strontium ranelate caused a slight decrease in the
absorption of strontium ranelate (20-25% AUC decrease), while absorption was almost unaffected
when the antacid was given two hours after strontium ranelate. It is therefore preferable to take
antacids at least two hours after OSSEOR. However, when this dosing regimen is impractical due to
the recommended administration of OSSEOR at bedtime, concomitant intake remains acceptable.
No interaction was observed with oral supplementation of vitamin D.
No evidence of clinical interactions or relevant increase of blood strontium levels with medicinal
products expected to be commonly prescribed concomitantly with OSSEOR in the target population
were found during clinical trials. These included: nonsteroidal anti-inflammatory agents (including
acetylsalicylic acid), anilides (such as paracetamol), H 2 blockers and proton pump inhibitors, diuretics,
digoxin and cardiac glycosides, organic nitrates and other vasodilators for cardiac diseases, calcium
channel blockers, beta blockers, ACE inhibitors, angiotensin II antagonists, selective beta-2
adrenoceptor agonists, oral anticoagulants, platelet aggregation inhibitors, statins, fibrates and
benzodiazepine derivatives.
4.6 Fertility, pregnancy and lactation
Pregnancy
OSSEOR is only intended for use in postmenopausal women.
There are no data from the use of strontium ranelate in pregnant women.
At high doses, animal studies have shown reversible bone effects in the offspring of rats and rabbits
treated during pregnancy (see section 5.3). If OSSEOR is used inadvertently during pregnancy,
treatment must be stopped.
Breast-feeding
Physico-chemical data suggest excretion of Strontium ranelate in human milk OSSEOR should not be
used during breast-feeding
Fertility
No effects were observed on males and females fertility in animal studies.
4.7 Effects on ability to drive and use machines
Strontium ranelate has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
OSSEOR has been studied in clinical trials involving nearly 8,000 participants. Long-term safety has
been evaluated in postmenopausal women with osteoporosis treated for up to 60 months with
strontium ranelate 2 g/day (n=3,352) or placebo (n=3,317) in phase III studies. Mean age was 75 years
at inclusion and 23% of the patients enrolled were 80 to 100 years of age.
4
There were no differences in the nature of adverse reactions between treatment groups regardless of
whether patients were aged below or above 80 at inclusion.
Overall incidence rates for adverse reactions with strontium ranelate did not differ from placebo and
adverse reactions were usually mild and transient. The most common adverse reactions consisted of
nausea and diarrhoea, which were generally reported at the beginning of treatment with no noticeable
difference between groups afterwards. Discontinuation of therapy was mainly due to nausea (1.3% and
2.2% in the placebo and strontium ranelate groups respectively).
In phase III studies, the annual incidence of venous thromboembolism (VTE) observed over 5 years
was approximately 0.7%, with a relative risk of 1.4 (95% CI = [1.0 ; 2.0]) in strontium ranelate treated
patients as compared to placebo (see section 4.4).
The following adverse reactions have been reported during clinical studies and/or post marketing use
with Strontium ranelate.Adverse reactions, defined as adverse events considered at least possibly
attributable to strontium ranelate treatment in phase III studies are listed below using the following

4.9 Overdose
Good tolerance was shown in a clinical study investigating the repeated administration of 4 g
strontium ranelate per day over 25 days in healthy postmenopausal women. Single administration of
doses up to 11 g in healthy young male volunteers did not cause any particular symptoms.
Following episodes of overdoses during clinical trials (up to 4 g/day for a maximal duration of
147 days), no clinically relevant events were observed.
Administration of milk or antacids may be helpful to reduce the absorption of the active substance. In
the event of substantial overdose, vomiting may be considered to remove unabsorbed active substance.

PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Drugs for the treatment of bone diseases - Other drugs affecting bone
structure and mineralisation, ATC code: M05BX03
Mechanism of action
In vitro , strontium ranelate:
- increases bone formation in bone tissue culture as well as osteoblast precursor replication and
collagen synthesis in bone cell culture;
- reduces bone resorption by decreasing osteoclast differentiation and resorbing activity.
This results in a rebalance of bone turnover in favour of bone formation.
6
Common:
Frequency unknown: a
 
The activity of strontium ranelate was studied in various non-clinical models. In particular, in intact
rats, strontium ranelate increases trabecular bone mass, trabeculae number and thickness; this results in
an improvement of bone strength.
In bone tissue of treated animals and humans, strontium is mainly adsorbed onto the crystal surface
and only slightly substitutes for calcium in the apatite crystal of newly formed bone. Strontium
ranelate does not modify the bone crystal characteristics. In iliac crest bone biopsies obtained after up
to 60 months of treatment with strontium ranelate 2 g/day in phase III trials, no deleterious effects on
bone quality or mineralisation were observed.
The combined effects of strontium distribution in bone (see section 5.2) and increased X-ray
absorption of strontium as compared to calcium, leads to an amplification of bone mineral density
(BMD) measurement by dual-photon X-ray absorptiometry (DXA). Available data indicate that these
factors account for approximately 50% of the measured change in BMD over 3 years of treatment with
OSSEOR 2 g/day. This should be taken into account when interpreting BMD changes during
treatment with OSSEOR. In phase III studies, which demonstrated the anti-fracture efficacy of
OSSEOR treatment, measured mean BMD increased from baseline with OSSEOR by approximately
4% per year at the lumbar spine and 2% per year at the femoral neck, reaching 13% to 15% and 5% to
6% respectively after 3 years, depending on the study.
In phase III studies, as compared to placebo, biochemical markers of bone formation (bone-specific
alkaline phosphatase and C-terminal propeptide of type I procollagen) increased and those of bone
resorption (serum C-telopeptide and urinary N-telopeptide cross links) decreased from the third month
of treatment up to 3 years.
Secondary to the pharmacological effects of strontium ranelate, slight decreases in calcium and
parathyroid hormone (PTH) serum concentrations, increases in blood phosphorus concentrations and
in total alkaline phosphatase activity were observed, with no observed clinical consequences.
Clinical efficacy
Osteoporosis is defined as BMD of the spine or hip 2.5 SD or more below the mean value of a normal
young population. A number of risk factors are associated with postmenopausal osteoporosis including
low bone mass, low bone mineral density, early menopause, a history of smoking and a family history
of osteoporosis. The clinical consequence of osteoporosis is fractures. The risk of fractures is
increased with the number of risk factors.
Treatment of postmenopausal osteoporosis:
The anti-fracture studies program of OSSEOR was made up of two placebo-controlled phase III
studies: SOTI study and TROPOS study. SOTI involved 1,649 postmenopausal women with
established osteoporosis (low lumbar BMD and prevalent vertebral fracture) and a mean age of
70 years. TROPOS involved 5,091 postmenopausal women with osteoporosis (low femoral neck BMD
and prevalent fracture in more than half of them) and a mean age of 77 years. Together, SOTI and
TROPOS enrolled 1,556 patients over 80 years at inclusion (23.1% of the study population). In
addition to their treatment (2 g/day strontium ranelate or placebo), the patients received adapted
calcium and vitamin D supplements throughout both studies.
OSSEOR reduced the relative risk of new vertebral fracture by 41% over 3 years in the SOTI study
(table 1). The effect was significant from the first year. Similar benefits were demonstrated in women
with multiple fractures at baseline. With respect to clinical vertebral fractures (defined as fractures
associated with back pain and/or a body height loss of at least 1 cm), the relative risk was reduced by
38%. OSSEOR also decreased the number of patients with a body height loss of at least 1 cm as
compared to placebo. Quality of life assessment on the QUALIOST specific scale as well as the
General Health perception score of the SF-36 general scale indicated benefit of OSSEOR, compared
with placebo.
Efficacy of OSSEOR to reduce the risk of new vertebral fracture was confirmed in the TROPOS
study, including for osteoporotic patients without fragility fracture at baseline.

In patients over 80 years of age at inclusion, a pooled analysis of SOTI and TROPOS studies showed
that OSSEOR reduced the relative risk of experiencing new vertebral fractures by 32% over 3 years
(incidence of 19.1% with strontium ranelate vs. 26.5% with placebo).
In an a-posteriori analysis of patients from the pooled SOTI and TROPOS studies with baseline
lumbar spine and / or femoral neck BMD in the osteopenic range and without prevalent fracture but
with at least one additional risk factor for fracture (N=176), OSSEOR reduced the risk of a first
vertebral fracture by 72% over 3 years (incidence of vertebral fracture 3.6% with strontium ranelate
vs. 12.0% with placebo).
An a-posteriori analysis was performed on a subgroup of patients from the TROPOS study of
particular medical interest and at high-risk of fracture [defined by a femoral neck BMD T-score ≤ -
3 SD (manufacturer’s range corresponding to -2.4 SD using NHANES III) and an age ≥ 74 years
(n=1,977, i.e. 40% of the TROPOS study population)]. In this group, over 3 years of treatment,
OSSEOR reduced the risk of hip fracture by 36% relative to the placebo group (table 2).

paediatric use).
5.2 Pharmacokinetic properties
Strontium ranelate is made up of 2 atoms of stable strontium and 1 molecule of ranelic acid, the
organic part permitting the best compromise in terms of molecular weight, pharmacokinetics and
acceptability of the medicinal product. The pharmacokinetics of strontium and ranelic acid have been
assessed in healthy young men and healthy postmenopausal women, as well as during long-term
exposure in postmenopausal osteoporotic women including elderly women.
Due to its high polarity, the absorption, distribution and binding to plasma proteins of ranelic acid are
low. There is no accumulation of ranelic acid and no evidence of metabolism in animals and humans.
Absorbed ranelic acid is rapidly eliminated unchanged via the kidneys.
8
 
Absorption
The absolute bioavailability of strontium is about 25% (range 19-27%) after an oral dose of 2 g
strontium ranelate. Maximum plasma concentrations are reached 3-5 hours after a single dose of 2 g.
Steady state is reached after 2 weeks of treatment. Intake of strontium ranelate with calcium or food
reduces the bioavailability of strontium by approximately 60-70%, compared with administration
3 hours after a meal. Due to the relatively slow absorption of strontium, food and calcium intake
should be avoided both before and after administration of OSSEOR. Oral supplementation with
vitamin D has no effect on strontium exposure.
Distribution
Strontium has a volume of distribution of about 1 l/kg. The binding of strontium to human plasma
proteins is low (25%) and strontium has a high affinity for bone tissue. Measurement of strontium
concentration in iliac crest bone biopsies from patients treated for up to 60 months with strontium
ranelate 2 g/day indicate that bone strontium concentrations may reach a plateau after about 3 years of
treatment. There are no data in patients to demonstrate elimination kinetics of strontium from bone
off-therapy.
Biotransformation
As a divalent cation, strontium is not metabolised. Strontium ranelate does not inhibit cytochrome
P450 enzymes.
Elimination
The elimination of strontium is time and dose independent. The effective half-life of strontium is about
60 hours. Strontium excretion occurs via the kidneys and the gastrointestinal tract. Its plasma
clearance is about 12 ml/min (CV 22%) and its renal clearance about 7 ml/min (CV 28%).
Pharmacokinetics in special clinical situations
Elderly
Population pharmacokinetic data showed no relationship between age and apparent clearance of
strontium in the target population.
Patients with renal impairment
In patients with mild-to-moderate renal impairment (30-70 ml/min creatinine clearance), strontium
clearance decreases as creatinine clearance decreases (approximately 30% decrease over the creatinine
clearance range 30 to 70 ml/min) and thereby induces an increase in strontium plasma levels. In phase
III studies, 85% of the patients had a creatinine clearance between 30 and 70 ml/min and 6% below
30 ml/min at inclusion, and the mean creatinine clearance was about 50 ml/min. No dosage adjustment
is therefore required in patients with mild-to-moderate renal impairment.
There is no pharmacokinetic data in patients with severe renal impairment (creatinine clearance below
30 ml/min).
Patients with hepatic impairment
There is no pharmacokinetic data in patients with hepatic impairment. Due to the pharmacokinetic
properties of strontium, no effect is expected.
5.3 Preclinical safety data
Non-clinical data revealed no special hazard for humans based on conventional studies of safety
pharmacology, genotoxicity and carcinogenic potential.
Chronic oral administration of strontium ranelate at high doses in rodents induced bone and tooth
abnormalities, mainly consisting of spontaneous fractures and delayed mineralisation. These effects
were reported at bone strontium levels 2-3 times higher than long-term clinical bone strontium levels
and were reversible after cessation of treatment.
9
Developmental toxicity studies in rats and rabbits resulted in bone and tooth abnormalities (e.g. bent
long bones and wavy ribs) in the offspring. In rats, these effects were reversible 8 weeks after
cessation of treatment.

Further information
1.
WHAT OSSEOR IS AND WHAT IT IS USED FOR
OSSEOR is a non-hormonal medicine used to treat osteoporosis in postmenopausal women. OSSEOR
reduces the risk of fracture at the spine and at the hip.
About osteoporosis
Your body is constantly breaking down old bone and making new bone tissue. If you have
osteoporosis, your body breaks down more bone than it forms so that gradually bone loss occurs and
your bones become thinner and fragile. This is especially common in women after the menopause.
Many people with osteoporosis have no symptoms and you may not even know that you have it.
However, osteoporosis makes you more likely to have fractures (break bones), especially in your
spine, hips and wrists.
How OSSEOR works
OSSEOR, which contains the substance strontium ranelate, belongs to a group of medicines used to
treat bone diseases.
OSSEOR works by reducing bone breakdown and stimulating rebuilding of bone and therefore
reduces the risk of fracture. The newly formed bone is of normal quality.
2.
BEFORE YOU TAKE OSSEOR
Do not take OSSEOR:
-
if you are allergic (hypersensitive) to strontium ranelate or any of the other ingredients of
OSSEOR.
Take special care with OSSEOR:
Before taking OSSEOR talk to your doctor :
-
if you are being treated or have been treated for blood clots.
-
if you are confined to bed or if you are to undergo an operation. The risk of vein thrombosis
(blood clots in the leg) may be increased in the event of lengthy immobilisation.
-
26
4.
Possible side effects
-
if you have severe kidney disease.
During treatment, if you experience an allergic reaction (such as swelling of the face, tongue or throat,
difficulty in breathing or swallowing, skin rash), you must immediately stop taking OSSEOR and seek
medical advice. If you have stopped treatment due to hypersensitivity reactions it should be permanent
and you should not re-start therapy with OSSEOR.
Use in children
OSSEOR is not intended for use in children and adolescents (below the age of 18).
Taking other medicines:
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription.
-You should stop taking OSSEOR if you have to take oral tetracyclines or quinolones (two types of
antibiotics). You can take OSSEOR again when you have finished taking these antibiotics. If you are
unsure about this ask your doctor or pharmacist.
- If you are taking medicines containing calcium, you should leave at least 2 hours before you take
OSSEOR.
- If you take antacids (medicines to relieve heartburn) you should take them at least 2 hours after
OSSEOR. If this is not possible, it is acceptable to take the two medicines at the same time.
Taking OSSEOR with food and drink:
Food, milk and milk products reduce the absorption of strontium ranelate. It is recommended that you
take OSSEOR in-between meals, preferably at bedtime at least two hours after food, milk or milk
products or calcium supplements.
Pregnancy and breast-feeding:
OSSEOR is meant for use only in postmenopausal women. Therefore, do not take OSSEOR during
pregnancy or when you are breastfeeding. If you take it by accident during pregnancy or
breastfeeding, stop taking it straight away and talk to your doctor.
Driving and using machines:
Osseor is unlikely to affect your ability to drive or use machines.
Important information about some of the ingredients of OSSEOR:
OSSEOR contains aspartame. If you suffer from phenylketonuria (a rare, hereditary disorder of the
metabolism) talk to your doctor before you start to take this medicine.
3.
HOW TO TAKE OSSEOR
Always take OSSEOR exactly as your doctor has told you. You should check with your doctor or
pharmacist if you are not sure.
OSSEOR is for oral use.
The recommended dose is one 2g sachet a day.
It is recommended that you take OSSEOR at bedtime, preferably at least 2 hours after dinner. You
may lie down immediately after taking OSSEOR if you wish.
Take the granules contained in the sachets as a suspension in a glass of water (see instructions below).
OSSEOR can interact with milk and milk products, so it is important that you mix OSSEOR only with
water to be sure it works properly.
27
Empty the granules from the sachet into a glass;
Add water;
Stir until the granules are evenly dispersed in the water.
Drink straight away. You should not leave it more than 24 hours before you drink it. If for some
reason you cannot drink the medicine straight away, make sure you stir it again before drinking.
Your doctor may advise you to take calcium and vitamin D supplements in addition to OSSEOR. Do
not take calcium supplements at bedtime, at the same time as OSSEOR.
Your doctor will tell you how long you should continue to take OSSEOR. Osteoporosis-therapy is
usually required for a long period. It is important that you continue taking OSSEOR for as long as
your doctor prescribes the medicine.
If you take more OSSEOR than you should:
If you take too many sachets of OSSEOR, tell your doctor or pharmacist. They may advise you to
drink milk or take antacids to reduce the absorption of the active ingredient.
If you forget to take OSSEOR:
Do not take a double dose to make up for forgotten individual doses. Just carry on with the next dose
at the normal time.
4.

in breathing or swallowing), swelling in limbs, feeling confused, bronchial hyperreactivity (symptoms
