Ferrous fumarate

Generic name: Ferrous Fumarate
Dosage form: oral tablet (300 mg; 324 mg; 325 mg)
Drug class: Iron products

Usage of Ferrous fumarate

Ferrous fumarate is a type of iron. You normally get iron from the foods you eat. In your body, iron becomes a part of your hemoglobin (HEEM o glo bin) and myoglobin (MY o glo bin). Hemoglobin carries oxygen through your blood to tissues and organs. Myoglobin helps your muscle cells store oxygen.

Ferrous fumarate is used to treat iron deficiency anemia (a lack of red blood cells caused by having too little iron in the body).

Ferrous fumarate may also be used for purposes not listed in this medication guide.
