What is ferumoxytol?

Ferumoxytol 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.

Ferumoxytol is used to treat iron deficiency anemia in people with chronic kidney disease. Anemia is a lack of red blood cells caused by having too little iron in the body.
