This medication is used to treat "iron-poor" blood (iron deficiency anemia). Ferumoxytol is a form of injectable iron that is used if you cannot take iron by mouth because of side effects or an unsuccessful response to treatment. It is also used by people who have anemia due to long-term kidney disease.

Iron is an important part of your red blood cells and is needed to carry oxygen throughout the body. Many people with kidney disease cannot get enough iron from food and require injections. People with kidney disease may also need extra iron because of blood loss during kidney dialysis treatment.

Read the Patient Information Leaflet if available from your pharmacist before you start using ferumoxytol and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Ferumoxytol is given by a health care professional. It is given by slow injection into a vein over at least 15 minutes, usually in a clinic or hospital. Treatment involves receiving two doses of ferumoxytol, given 3 to 8 days apart. It may be given during dialysis.

The dosage is based on your medical condition and response to treatment. Your doctor will take blood tests to monitor your response to treatment.
