What is the most important information I should know about ferumoxytol?

You should not use ferumoxytol 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.

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 (a lack of red blood cells caused by having too little iron in the body).

Ferumoxytol injection is used in people with chronic kidney disease, or in people unable to take oral iron (by mouth) or who have not responded well to oral iron.

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

What should I discuss with my healthcare provider before receiving ferumoxytol?

You should not use this medicine if:

  • you have had an allergic reaction to an injectable form of iron (including ferumoxytol); or
  • you have any type of anemia that is not caused by iron deficiency.

Tell your doctor if you have ever had:

  • iron load syndrome;
  • any drug allergies; or
  • low blood pressure.

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant.

How is ferumoxytol given?

Ferumoxytol is given as an infusion into a vein. A healthcare provider will give you this injection, which can take up to 15 minutes to complete.

You will be watched closely for at least 30 minutes after receiving ferumoxytol, to make sure you do not have an allergic reaction to the medicine.

Ferumoxytol is usually given as a single injection followed by a second injection 3 to 8 days later.

You may need frequent medical tests to help your doctor determine how long to treat you with ferumoxytol.

Ferumoxytol can cause unusual results with magnetic resonance imaging (MRI) tests for up to 3 months after you receive this medication. After you receive a ferumoxytol injection, you should wait at least 4 weeks before having an MRI. Tell any doctor who treats you that you have received a ferumoxytol injection.

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