Ferumoxytol Injection

Brand Name(s): Feraheme®

WHY is this medicine prescribed?

Ferumoxytol injection is used to treat iron-deficiency anemia (a lower than normal number of red blood cells due to too little iron) in adults with chronic kidney disease (damage to the kidneys which may worsen over time and may cause the kidneys to stop working). Ferumoxytol injection is used to treat iron-deficiency anemia in people who did not respond or are unable to tolerate taking iron preparations by mouth. Ferumoxytol injection is in a class of medications called iron replacement products. It works by replenishing iron stores so that the body can make more red blood cells.

HOW should this medicine be used?

Ferumoxytol injection comes as a solution (liquid) to inject intravenously (into a vein) by a doctor or nurse in a medical office or hospital outpatient clinic. It is usually injected slowly over at least 15 minutes. Ferumoxytol injection is usually given as a total of two doses, spaced 3 to 8 days apart. If your iron levels become or remain low after you finish your treatment, your doctor may prescribe this medication again.

Are there OTHER USES for this medicine?
