What is Hydroxycarbamide?
Hydroxycarbamide, the active ingredient in Hydroxyurea, is an antineoplastic agent presented as an oral dosage form for oral use. It is used to treat certain blood disorders and cancers, including chronic myelogenous leukemia, sickle cell disease, polycythemia vera, and essential thrombocythemia.
GNH USA supplies Hydroxyurea as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, oncology centres, pharmacies and clinics worldwide.
What is Hydroxycarbamide used for?
Hydroxyurea is employed in hematologic malignancies and chronic blood disorders. - Chronic myelogenous leukemia: reduces leukemic cell proliferation. - Sickle cell disease: decreases frequency of painful vaso‑occlusive crises. - Polycythemia vera: lowers elevated red blood cell mass. - Essential thrombocythemia: reduces platelet count and thrombotic risk.
What are the side effects of Hydroxycarbamide?
Hydroxyurea may cause a range of adverse reactions, varying from mild to severe.
Common Side Effects: - Bone marrow suppression: anemia, leukopenia, thrombocytopenia. - Gastrointestinal upset: nausea, vomiting, diarrhea. - Skin changes: hyperpigmentation, rash. - Alopecia: hair thinning or loss.
Serious or Rare Side Effects: - Severe cytopenias: life‑threatening neutropenia or aplastic anemia. - Acute renal failure. - Pulmonary toxicity: interstitial pneumonitis or fibrosis.
What precautions apply to Hydroxycarbamide?
Hydroxyurea requires careful monitoring and specific safety measures. - Pregnancy: category D; avoid unless benefits outweigh risks. - Breastfeeding: not recommended; drug may be excreted in milk. - Renal impairment: dose adjustment may be needed; monitor renal function. - Hepatic impairment: use with caution; monitor liver enzymes. - Myelosuppression monitoring: perform regular complete blood counts. - Store at room temperature: keep in original container, protect from moisture and light.
What does Hydroxycarbamide interact with?
Hydroxyurea can interact with several medicines, altering efficacy or toxicity.
Major Interactions (Avoid): - Concurrent myelosuppressive agents: may cause profound bone marrow suppression. - Live vaccines: increased risk of infection due to immunosuppression. - Protease inhibitor antiretrovirals: may raise hydroxyurea plasma concentrations.
Moderate Interactions (Monitor Closely): - Allopurinol: can enhance hematologic toxicity. - Phenytoin: may reduce hydroxyurea effectiveness. - NSAIDs: may increase risk of renal toxicity.
