What is Hydrea (Hydroxyurea) used for?
Reducing the number of painful episodes and blood transfusions needed by adults with sickle cell anemia experiencing recurrent episodes associated with moderate to severe pain. It may also be used for other conditions as determined by your doctor. Hydroxyurea is an antineoplastic agent. Exactly how it works is unknown, but it is thought to increase the ability of deformed red blood cells to change shape, which may lessen pain associated with sickle cell anemia.
