Droxia, the active ingredient hydroxyurea, is used in patients with sickle cell anemia. The drug is available in capsule form and is available in concentrations of 200 mg, 300 mg and 400 mg of hydroxyurea.

Hydroxyurea is prescribed to people with sickle cell anemia to reduce the amount of pain caused by the disease and reduce the need for blood transfusions. Some brand name drugs are also used to treat certain types of cancer (such as chronic myelogenous leukemia, squamous cell carcinoma). However, it is necessary to pay attention to the side effects of hydroxyurea drugs during use.
