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 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 over approximately 1 minute or may be mixed with another fluid and administered 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.

Ferumoxytol injection may cause severe or life-threatening reactions during and shortly after you receive the medication. Your doctor will watch you carefully while you receive each dose of ferumoxytol injection and for at least 30 minutes afterwards. Tell your doctor if you experience any of the following symptoms during or after your injection: shortness of breath; wheezing; difficulty swallowing or breathing; hoarseness; swelling of the face, throat, tongue, lips, or eyes; hives; rash; itching; fainting; lightheadedness; dizziness; cold, clammy skin; rapid, weak pulse; slow heartbeat; or loss of consciousness. If you experience a severe reaction, your doctor will stop your infusion immediately and provide emergency medical treatment.
