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 heart and liver, reducing the risk of organ damage. Also used in cases of iron overload from other causes, including non-transfusion-dependent thalassemias and certain myelodysplastic syndromes. Its oral formulation offers a convenient alternative to older chelation therapies that require injections.
