    Iron is an essential component in the formation of hemoglobin. Adequate amounts of iron are necessary for effective erythropoiesis. Iron also serves as a cofactor of several essential enzymes, including cytochromes that are involved in electron transport.

    Folic acid is required for nucleoprotein synthesis and the maintenance of normal erythropoiesis. Folic acid is converted in the liver and plasma to its metabolically active form, tetrahydrofolic acid, by dihydrofolate reductase.

    Vitamin B 12 is required for the maintenance of normal erythropoiesis, nucleoprotein and myelin synthesis, cell reproduction and normal growth. Intrinsic factor, a glycoprotein secreted by the gastric mucosa, is required for active absorption of Vitamin B 12 from the gastrointestinal tract.


    For the treatment of all anemias responsive to oral iron therapy, such as hypochromic anemia associated with pregnancy, chronic or acute blood loss, dietary restriction, metabolic disease and post-surgical convalescence.


    This product is contraindicated in patients with a known hypersensitivity to any of the ingredients. Hemochromatosis and hemosiderosis are contraindications to iron therapy.


    Folic acid alone is improper therapy in the treatment of pernicious anemia and other megaloblastic anemias where Vitamin B 12 is deficient.

    WARNING:    Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.



    Do not exceed recommended dose.

    The type of anemia and the underlying cause or causes should be determined before starting therapy with Repliva 21/7™ Tablets. Since the anemia may be a result of a systemic disturbance, such as recurrent blood loss, the underlying cause or causes should be corrected, if possible.

    Folic Acid

    Folic acid in doses above 1.0 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurological manifestations remain progressive. Pernicious anemia should be excluded before using this product since folic acid may mask the symptoms of pernicious anemia.

    Pediatric Use

    Safety and effectiveness in pediatric patients have not been established.

    Geriatric Use

    Clinical studies on this product have not been performed in sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.


    Adverse reactions with iron therapy may include constipation, diarrhea, nausea, vomiting, dark stools and abdominal pain. Adverse reactions with iron therapy are usually transient.

    Allergic sensitization has been reported following both oral and parenteral administration of folic acid.


    The clinical course of acute iron overdosage can be variable. Initial symptoms may include abdominal pain, nausea, vomiting, diarrhea, tarry stools, melena, hematemesis, hypotension, tachycardia, metabolic acidosis, hyperglycemia, dehydration, drowsiness, pallor, cyanosis, lassitude, seizures, shock and coma.


    Usual adult dose is 1 tablet daily, or as directed by a physician. The Repliva 21/7™ TheraPak supplies a 28-day course of iron therapy that consists of 21 red active tablets and 7 purple inactive tablets. Take 1 red tablet daily for 21 days, followed by 1 purple tablet daily for 7 days. After 28 tablets have been taken, a new course may be started if prescribed.
