Iron overload is an unfortunate clinical consequence of repeated blood transfusions that can cause significant organ damage, morbidity, and mortality in the absence of proper treatment. Pediatric patients with transfusion-dependent pathologies face the additional risk of growth failure and poor sexual development owing to iron build-up in the anterior pituitary gland. Iron chelation therapy is necessary for the removal of excess iron, but treatment efficacy and success are highly dependent on patient compliance. Deferoxamine is a well-established but inconvenient therapy requiring parenteral administration over extended periods of time. Patient compliance can be improved with use of the oral iron chelators deferasirox and deferiprone. Long-term data have shown deferasirox to have a good safety and efficacy profile in pediatric patients.
