A complication of the frequent blood transfusions in thalassemia is iron overload.Chelation therapy with deferoxamine (an iron-chelating agent)is given with oral supplements of vitamin C to increase iron excretion.Chelation therapy treats the side effect of the disease management.Decreasing the risk of hypoxia and managing nausea and vomiting are not the purposes of chelation therapy.
