Droxia (generic: hydroxyurea) is a prescription medication used to reduce the frequency of episodes of severe pain from sickle cell anemia and to reduce the need for blood transfusions in adults with sickle cell anemia.  Droxia belongs to a group of drugs called antineoplastic agents. How it works is not known. It may prevent red blood cells from bending into the wrong shape, and by reducing the number of white blood cells and/or increasing red blood cells that carry fetal hemoglobin (HbF).

This medication comes in capsule form and is usually taken once a day, with or without food. Drink 8 to 10 glasses of water each day while you are taking Droxia.

Some of the common side effects of Droxia include hair loss, fever, and stomach problems.
