Hydroxyurea
Hydroxyurea 500mg Capsule
Hydroxyurea is an antimetabolite and anti-cancer drug that works by interfering with DNA synthesis, thereby slowing or stopping the growth of cancer cells.
In blood disorders, it stimulates the production of fetal hemoglobin (HbF), which helps prevent red blood cells from sickling, improving circulation.
Main Indication
Chronic Myeloid Leukemia (CML): Helps control white blood cell count in cases resistant to other treatments.
Sickle Cell Disease: Reduces the frequency of painful crises and decreases the need for blood transfusions.
Head and Neck Cancer: Used alongside radiation therapy to enhance treatment effectiveness.
Polycythemia Vera: Prevents excess production of red blood cells.
How Do You Take This Drug?
Administration: Take capsules whole with a full glass of water. Do not crush or chew, as the powder inside is harmful if inhaled or touched.
Dosing: Determined based on body weight and blood test results, with adjustments made accordingly.
Consistency: Take at the same time daily. If a dose is missed, consult your doctor—do not double the dose.
