Jadenu (Deferasirox) Dosage and Side Effects
This medication is used to treat ongoing high levels of iron in the body caused by multiple blood transfusions. It is also used to treat high levels of iron in people with a certain blood disorder who do not require blood transfusions (non-transfusion-dependent thalassemia). It works by binding to iron, allowing the body to pass extra iron out in the stool. Deferasirox belongs to a class of drugs known as iron-chelating agents.
