Deferasirox is a medication used to treat chronic iron overload in patients, particularly those with conditions like thalassemia or sickle cell disease. It works by binding to excess iron in the body, allowing it to be excreted through the urine. This helps prevent damage to vital organs caused by iron accumulation. The drug is typically taken orally in tablet form and is prescribed based on the patient's specific needs and iron levels. Regular monitoring of liver and kidney function is essential during treatment to ensure safety and effectiveness.
