What is deferoxamine?
Deferoxamine binds to iron and removes it from the bloodstream.
Deferoxamine is used to treat acute (immediate) iron overdose.
Deferoxamine is also used to treat chronic (long-term) iron overload caused by repeated blood transfusions.
Deferoxamine may also be used for purposes not listed in this medication guide.
What should I discuss with my health care provider before using deferoxamine?
You should not use deferoxamine if you are allergic to it, or if you have:
- severe kidney disease; or
- if you are unable to urinate.
Tell your doctor if you have ever had:
- kidney disease (or if you are on dialysis);
- heart disease;

- vision or hearing problems;
- asthma or other breathing disorder;
- low levels of calcium in your blood (hypocalcemia); or

If you need to have any type of x-ray or CT scan using a dye that is injected into a vein, you may need to temporarily stop using deferoxamine. Be sure the doctor knows ahead of time that you are using deferoxamine.

How should I use deferoxamine?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Deferoxamine is sometimes injected into a muscle. Deferoxamine may also be given over 8 to 24 hours using an infusion pump attached to a catheter placed under your skin or into a vein. A healthcare provider may teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Deferoxamine must be mixed with a liquid (diluent) before using it. When using injections by yourself, be sure you understand how to properly mix and store the medicine.
Prepare an injection only when you are ready to give it. It is best to use deferoxamine within 3 hours after mixing it. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.
Throw away the medicine if it has been longer than 24 hours since it was mixed with the liquid.
Your doctor may tell you to take a vitamin C supplement. Follow all instructions about how much vitamin C to take and when to start taking it. Using too much vitamin C while you are using deferoxamine can cause heart problems.
Do not take vitamin C supplements without your doctor's advice if you have heart failure.
You will need frequent medical tests. You may also need eye exams. If a child is using deferoxamine, a doctor should check the child's growth every 3 months.
Each dose of deferoxamine is for one use only. Throw away any mixed medicine that is leftover after giving the injection.
Store deferoxamine at room temperature. You may store mixed medicine at room temperature for up to 24 hours, but do not refrigerate it.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
