Deferiprone is used to remove excess iron in the body in people who have received a large number of blood transfusions to treat thalassemia (an inherited condition that causes a low number of red blood cells) and who have not benefitted enough from other treatments for excess iron. Deferiprone is in a class of medications called iron chelators. It works by attaching to iron in the body so that it can be excreted (removed from the body).

- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. You should use birth control so that you will not become pregnant during your treatment with deferiprone. Talk to your doctor about which method of birth control you should use. If you become pregnant while taking deferiprone, call your doctor immediately. Deferiprone may harm the fetus.
Dosage Of Deferiprone
Deferiprone comes as a tablet to take by mouth. It is usually taken three times a day, in the morning, at mid-day, and in the evening. Deferiprone may be taken with or without food, but taking it with meals may help to prevent nausea that may be caused by the medication. Take deferiprone at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take deferiprone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If your dose includes half of a tablet, split a tablet carefully on the score mark.
Your doctor may adjust your dose of deferiprone every 2 to 3 months depending on your laboratory test results.
Keep all appointments with your doctor and the laboratory. Your doctor will order lab tests to check your body’s response to deferiprone.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
