Deferiprone (Ferriprox) is a medication used to treat iron overload (too much iron in the body) in people with certain blood conditions, like sickle cell disease or anemia, after they've received a blood transfusion. It comes in a tablet and solution formulation. The solution is only available as a brand-name medication, but there's a lower-cost generic version of the tablets.
Deferiprone (Ferriprox) is a chelating agent. It works by attaching to iron in the body and forming a chemical compound that isn't harmful to you. Your body then gets rid of this iron compound by passing it through your urine.
People with certain blood conditions sometimes need blood transfusions because their bodies don't make blood as well as other people. Receiving frequent blood transfusions puts you at risk for excess iron buildup in different organs in your body, which can lead to organ damage. This is known as transfusion iron overload.
Deferiprone (Ferriprox) helps get rid of the excess iron from blood transfusions that would otherwise be toxic to your body.

Deferiprone (Ferriprox) can cause extremely low white blood cells in your body. White blood cells play an important part in fighting off infections, so if they get too low, you're at risk for serious or deadly infections. You'll need to do a blood test to check your white blood cell count before you start taking deferiprone (Ferriprox) and regularly during treatment. You might need to stop taking the medication if your white blood cells drop too much. Report any signs of an infection to your provider right away.

You’ll need to do blood tests before you start taking deferiprone (Ferriprox) and throughout your treatment so your provider can check your liver. If your liver enzymes get too high, you might need to stop the medication temporarily.
Deferiprone (Ferriprox) can cause the zinc levels in your blood to get too low. This can lower your ability to fight infections and cause hair loss, diarrhea, sexual problems, and loss of appetite, among other things. Your healthcare provider will check your zinc levels before you start and throughout your treatment. You might need to take a zinc supplement if your levels drops too much.
Deferiprone (Ferriprox) might cause harm to your unborn baby, such as birth defects, if taken during pregnancy. Your healthcare provider will need to make sure you're not pregnant before starting the medication (e.g., through a pregnancy test).

If you’re a male taking deferiprone (Ferriprox) and your partner is a female who can become pregnant, also use contraception during treatment and for at least 3 months after your last dose. Talk to your provider about birth control options that are right for you.
