Anemia is usually well tolerated. Because of the high RBC turnover, folate stores are often depleted. Althogh no scientific evidence shows that patients develop folate deficiency, folic acid (1 mg/d) is commonly prescribed for adults to prevent development of megaloblastic anemia due to increased folate requirements caused by hemolysis. Folic acid supplementation may raise the Hb level and support a healthy reticulocyte response.
