The medication contains the active ingredient Hydroxyurea and is supplied as a 500 mg tablet. It belongs to the class of ribonucleotide-reductase inhibitors, which interfere with DNA synthesis in rapidly dividing cells. In addition to its approved uses for sickle cell disease, chronic myelogenous leukemia, polycythemia vera, and essential thrombocythemia, Hydroxyurea may be considered in selected off-label settings under specialist supervision. --- ## Quick Reference Facts **Active Ingredient** : Hydroxyurea **Form** : pill 500 mg **Primary Uses** : • Prevention of vaso-occlusive crises in sickle cell disease • Control of elevated blood counts in polycythemia vera and essential thrombocythemia • Cytoreduction in chronic myelogenous leukemia --- ## What is Hydroxyurea? Hydroxyurea is the generic version of medications containing the active compound Hydroxyurea. It is marketed under several brand names, including **Hydrea** and **Droxia**, and is widely prescribed worldwide for hematologic conditions. The drug was first synthesized in the 19th century and received FDA approval for sickle cell disease in 1998, later expanding to myeloproliferative neoplasms. As a generic product, Hydroxyurea offers the same pharmacologic profile as its branded counterparts while typically costing less for patients and health systems. --- ## How Hydroxyurea Works Hydroxyurea inhibits ribonucleotide reductase, the enzyme responsible for converting ribonucleotides into deoxyribonucleotides-the building blocks of DNA. By limiting deoxyribonucleotide availability, the drug slows DNA synthesis, preferentially affecting rapidly proliferating cells such as malignant hematopoietic clones and abnormal red-cell precursors. In sickle cell disease, Hydroxyurea’s inhibition of DNA synthesis leads to a modest increase in fetal hemoglobin (Hb F) production. Hb F does not participate in sickling; its presence dilutes the concentration of sickle hemoglobin (Hb S) and reduces red-cell rigidity, thereby decreasing vaso-occlusive events. For myeloproliferative disorders, the drug reduces the replication of abnormal myeloid progenitors, lowering elevated hemoglobin, hematocrit, or platelet counts. The onset of therapeutic effect can be observed within weeks, while the duration of action depends on the dosing schedule and individual marrow responsiveness. Hydroxyurea is metabolized primarily by hepatic pathways and excreted unchanged in the urine; renal impairment may prolong its half-life, necessitating dose adjustments. --- ## Conditions Treated with Hydroxyurea - **Sickle Cell Disease** - Hydroxyurea raises fetal hemoglobin levels, lessening sickling and decreasing the rate of painful crises, acute chest syndrome, and need for blood transfusions. - **Polycythemia Vera** - By suppressing erythroid progenitors, the drug helps maintain hematocrit within target ranges, reducing the risk of thrombosis and disease-related symptoms. - **Essential Thrombocythemia** - Cytoreduction of megakaryocytes lowers platelet counts, preventing thrombotic and hemorrhagic complications. - **Chronic Myelogenous Leukemia (CML)** - Historically, Hydroxyurea was used to control leukocytosis before the advent of tyrosine-kinase inhibitors; it remains an option when other agents are unavailable or contraindicated. Each indication benefits from Hydroxyurea’s ability to modulate abnormal blood-cell proliferation while offering an oral, once-daily (or BID) dosing schedule. --- ## Is Hydroxyurea the Right Medication for You? Hydroxyurea is most appropriate for adults with confirmed sickle cell disease who experience recurrent vaso-occlusive episodes despite optimal supportive care, and for patients with myeloproliferative neoplasms requiring cytoreductive therapy. Candidates should have adequate renal and hepatic function to tolerate dose titration, and must be willing to undergo regular laboratory monitoring (complete blood count, renal panel) because myelosuppression is dose-dependent. Contraindications include pregnancy, breastfeeding, severe bone-marrow failure, known hypersensitivity to the drug, and active uncontrolled infections. Patients with a history of leg ulcers or significant renal insufficiency should use Hydroxyurea only under close specialist supervision, as these conditions increase the risk of adverse events. In summary, Hydroxyurea is a valuable option when the therapeutic goal is to reduce sickling complications or to control excess blood-cell production, provided that the prescriber can ensure routine monitoring and manage potential toxicities. --- ## Buying Hydroxyurea from [our online pharmacy](https://liabilis.com/order-hydroxyurea-online-en.html) ### Why Choose Our Service?

Express delivery typically arrives within 7 days, while standard airmail may take up to 3 weeks, giving you flexibility according to your urgency and budget. --- ## Use: Dosing, Missed Dose, Overdose - **Standard Dosing** - Adults with sickle cell disease often start at 15 mg/kg once daily, adjusting upward to a maximum of 30 mg/kg based on hematologic response and tolerance. For polycythemia vera or essential thrombocythemia, an initial dose of 15 mg/kg twice daily is common, with titration to maintain target blood counts. Each tablet contains 500 mg; dosing is calculated in whole tablets or fractions as instructed by a clinician. - **Missed Dose** - If you remember a missed dose more than 12 hours after the scheduled time, take it as soon as possible. If the next dose is due within 12 hours, skip the missed tablet and resume the regular schedule; do not double-dose. - **Overdose** - Signs of overdose may include severe nausea, vomiting, profound bone-marrow suppression, or acute renal failure. Seek immediate medical attention or contact your local poison-control center. Treatment is supportive, focusing on hydration, monitoring blood counts, and managing complications. - **Practical Precautions** - Take Hydroxyurea with a full glass of water, preferably with food to lessen gastrointestinal upset. Avoid alcohol excess, as it can exacerbate liver toxicity. Do not operate heavy machinery or drive until you know how the medication affects you, especially during dose adjustments. --- ## Safety Information ### ⚠️ Who Should Not Take Hydroxyurea - Pregnant individuals (teratogenic risk) - Breastfeeding mothers (excreted in milk) - Patients with severe bone-marrow suppression (e.g., neutrophils < 1,000/µL) - Known hypersensitivity to Hydroxyurea or any tablet excipients - Uncontrolled infections or active malignancies requiring alternative chemotherapy ### Common Side Effects - **Myelosuppression** - mild anemia, neutropenia, or thrombocytopenia; usually reversible with dose reduction. - **Gastrointestinal upset** - nausea, vomiting, or mild abdominal discomfort; may improve with food intake. - **Cutaneous reactions** - rash or mild hyperpigmentation of the skin. - **Hair thinning** - transient alopecia reported in a minority of patients. Management typically involves routine blood-count monitoring every 2-4 weeks and adjusting the dose according to the severity of cytopenias. ### Serious Side Effects (Seek Immediate Medical Help) - **Severe bone-marrow failure** - marked pancytopenia with fever or bleeding. - **Leg ulcers** - painful, non-healing sores, especially on the lower extremities. - **Renal or hepatic toxicity** - sudden rise in creatinine or liver enzymes. - **Pulmonary toxicity** - dyspnea or unexplained cough. If any of these occur, discontinue Hydroxyurea and contact your healthcare provider promptly. ### Drug & Food Interactions - **Antiretrovirals (e.g., didanosine)** - increased risk of bone-marrow suppression. - **Other myelosuppressive agents** (e.g., azathioprine, methotrexate) - additive cytopenia. - **Non-steroidal anti-inflammatory drugs (NSAIDs)** - may heighten renal toxicity. - **Live vaccines** - reduced efficacy; avoid during significant immunosuppression. Always inform your prescriber of all concurrent medications, including over-the-counter products and herbal supplements. --- ## Off-Label and Investigational Uses of Hydroxyurea - **Sickle Cell Trait Carriers** - Some pilot studies have explored low-dose Hydroxyurea to modestly raise Hb F, though routine use is not endorsed. - **Melanoma** - Historically used as part of combination chemotherapy; contemporary trials focus on newer agents, but Hydroxyurea remains a reference comparator. - **Hereditary Spherocytosis** - Small case series suggest cytoreductive benefits in select patients with severe hemolysis. These applications are not approved by major regulatory agencies. Their efficacy and safety profiles remain under investigation, and treatment should only be pursued within a clinical trial or under specialist guidance. --- ## Storage & Handling - **Temperature** - Store tablets at 20-25 °C (68-77 °F). - **Moisture** - Keep the container tightly closed; avoid exposure to humidity. - **Light** - Protect from direct sunlight; store in the original packaging. - **Expiry** - Do not use tablets beyond the expiration date printed on the label. - **Disposal** - If a supply becomes obsolete, follow local pharmacy-take-back programs or discard according to hazardous-waste guidelines. --- ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel internationally with Hydroxyurea?** Yes, but carry the medication in its original labeled container, bring a copy of the prescription, and be aware of import regulations in your destination country. - **Should I avoid any specific foods while taking Hydroxyurea?** No major food restrictions exist, but maintaining a balanced diet supports overall marrow health.
