Hydrogem 500mg Capsule contains Hydroxyurea, an antineoplastic agent used primarily in the treatment of certain malignancies and hematologic disorders. Hydroxyurea acts by inhibiting ribonucleotide reductase, leading to a reduction in DNA synthesis and cell proliferation. It is commonly prescribed for chronic myeloid leukemia, polycythemia vera, essential thrombocythemia, and sickle cell anemia to reduce the frequency of painful crises. The recommended dosage varies depending on the condition being treated and patient response, and should be determined by a healthcare professional. Patients must undergo regular blood monitoring, including complete blood counts and renal and hepatic function tests, to detect potential myelosuppression or organ toxicity. Common adverse effects include bone marrow suppression, gastrointestinal disturbances such as nausea and vomiting, mucositis, and dermatologic reactions. Caution is advised in pregnant or breastfeeding women due to potential teratogenic effects. Hydrogem 500mg Capsule should be administered under strict medical supervision with adherence to prescribed dosing schedules. Patients are advised to report any signs of infection, unusual bleeding, or persistent side effects promptly. This medication is contraindicated in individuals with hypersensitivity to Hydroxyurea or severe bone marrow depression. Proper storage conditions should be maintained to preserve drug efficacy.
