Description
Deferiprone is used to remove excess iron from the body in patients with thalassemia, sickle cell disease, or anemia who have blood transfusions.
Deferiprone is an iron chelator (binder). It combines with iron in the blood. The combination of iron and deferiprone is then removed from the body by the kidneys. If you have too much iron in the body, it can damage various organs and tissues.
