Patient Education

Deferiprone


Deferiprone is used to remove excess iron in the body in adults and children 3 years of age and older who have thalassemia (an inherited condition that causes a low number of red blood cells). It is also used to remove excess iron in adults and children 3 years of age and older with sickle cell disease (an inherited blood disease) or other types of anemia (a lower than normal number of red blood cells). 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).
