Ferrous Fumarate

Indications

Ferrous Fumarate is used to prevent or treat iron deficiency anaemia. The prevention of iron deficiency during pregnancy usually requires a combination of iron and folic acid. Iron is usually found in foods and is necessary for the normal development of red blood cells. A lack of iron affects the development of the red blood cells and causes a reduction in the number of red blood cells found in the body (iron deficiency anaemia).

Pharmacology

Ferrous fumarate is an iron preparation that is used in the prevention and treatment of iron deficiency. The amount of elemental iron is 330 mg/g of ferrous fumarate.

Dosage & Administration

Iron-deficiency anemia:
  • Adult: Usual dose range: Up to 600 mg daily. May increase up to 1.2 g daily if necessary.
  • Child: Preterm neonate: 0.6-2.4 ml / kg daily; up to 6 yr: 2.5-5 ml bid.
Should be taken on an empty stomach. Best taken on an empty stomach. May be taken with meals to reduce GI discomfort.
