Hydroxyurea is used to treat cancer of the white blood cells called chronic myeloid leukemia (CML). It may also be given together with radiation treatment for head and neck cancer (advanced squamous cell cancer). Hydroxyurea interferes with the growth of cancer cells, which are eventually destroyed by the body.

Hydroxyurea is used to prevent painful episodes and reduce the need for blood transfusions in patients with sickle cell anemia. It works by making the red blood cells more flexible.
