Feraheme 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.

Feraheme is an iron replacement product that is used in adults used to treat iron deficiency anemia (IDA), which is low red blood cells caused by a lack of iron in the body.

Feraheme is given to adults with IDA and chronic kidney disease, or to adults with IDA when iron taken by mouth is not effective.

You should not use Feraheme if you have ever had an allergic reaction to an injectable form of iron (including ferumoxytol), or if you have iron overload syndrome or any type of anemia that is not caused by iron deficiency.

Ferumoxytol can cause severe and sometimes fatal allergic reactions, even if you have used this medicine before without any reaction. Get emergency medical help if you have hives, itching, wheezing, trouble breathing, swelling in your face or throat, or feeling like you might pass out. Watch for signs of allergic reaction for at least 30 minutes after your injection.

Feraheme can cause unusual results with magnetic resonance imaging (MRI) tests for up to 3 months after you receive this medication. Tell any doctor who treats you that you have received this injection within the past 3 months.

Feraheme will not affect other types of X-rays, CT scans, ultrasounds, or nuclear radiation imaging.

Feraheme is injected into a vein by a healthcare provider.

This medicine must be given slowly over 15 minutes.
