Used primarily to treat chronic iron overload in patients who receive frequent blood transfusions, such as those with thalassemia or other chronic anemias. It works by binding excess iron in the body and promoting its elimination through feces. This helps prevent iron accumulation in vital organs like the liver, heart, and endocrine glands, reducing the risk of organ damage and improving long-term outcomes. Also used in cases of non-transfusion-dependent thalassemia where iron overload occurs due to increased gastrointestinal absorption. Its oral administration offers a convenient alternative to older, injectable chelators, improving patient compliance.
