Hydroxyurea

Hydroxyurea is a prescription medication used to treat various conditions, including sickle cell disease, certain types of cancer, and blood disorders. It works by slowing down the growth of abnormal cells, making it effective in managing diseases like chronic myeloid leukemia (CML) and polycythemia vera. Hydroxyurea helps reduce the frequency of painful crises in sickle cell anemia and lowers the need for blood transfusions. It is available in capsule form and should be used under medical supervision.

Uses of Hydroxyurea

• Treatment of sickle cell disease
• Management of chronic myeloid leukemia (CML)
• Treatment of polycythemia vera (a blood disorder)
• Used in certain cases of head and neck cancers
• Helps reduce the need for blood transfusions in anemia patients

How Hydroxyurea Works

Hydroxyurea works by inhibiting the DNA synthesis of rapidly dividing cells, slowing down their growth. In sickle cell disease, it increases the production of fetal hemoglobin (HbF), reducing the formation of sickle-shaped red blood cells and preventing complications.

Benefits of Hydroxyurea

• Reduces sickle cell crisis episodes
• Decreases the need for blood transfusions
• Helps control abnormal blood cell production
• Improves blood flow and oxygen delivery
• Effective in managing certain cancers

How to Take Hydroxyurea

Hydroxyurea should be taken as prescribed by a doctor. It is usually taken once daily with or without food. The dosage depends on the medical condition, body weight, and patient response. Regular blood tests are required to monitor its effects and adjust the dose if needed.
