In cancer, HYDROXYUREA works by blocking an enzyme that is required for growing cells. This prevents the cancer cells from multiplying and growing. In sickle cell disease, it works by increasing fetal hemoglobin (HbF) (hemoglobin of unborn baby) levels in red blood cells (RBCs). This helps the RBCs accept a normal shape, recovers the flow of blood, and protects against problems like painful sickle cell attacks.
Take HYDROXYUREA as prescribed by your doctor. You are advised to take HYDROXYUREA for as long as your doctor has prescribed it for you depending on your medical conditions.
