What is Hydroxycarbamide?

Hydroxycarbamide, the active ingredient in Hydroxyurea Medac, is a ribonucleotide reductase inhibitor presented as an oral tablet for oral use. It treats chronic myelogenous leukemia, sickle cell disease, and polycythemia vera in appropriate patients.

GNH USA supplies Hydroxyurea Medac as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, oncology centres, pharmacies and clinics worldwide.

What is Hydroxycarbamide used for?

Hydroxyurea acts on malignant and abnormal blood cell proliferation, and is used in several hematologic disorders.

- Chronic myelogenous leukemia: reduces leukemic cell growth and helps achieve hematologic remission. - Sickle cell disease: increases fetal hemoglobin levels, decreasing vaso‑occlusive crises. - Polycythemia vera: lowers elevated red blood cell mass and helps control hematocrit.

What are the side effects of Hydroxycarbamide?

Hydroxyurea may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Myelosuppression: decreased white blood cells, platelets, or red cells. - Gastrointestinal upset: nausea, vomiting, or abdominal pain. - Skin changes: hyperpigmentation or rash. - Alopecia: hair thinning or loss. - Elevated uric acid: risk of gout.

Serious or Rare Side Effects: - Severe bone marrow failure: aplastic anemia. - Acute renal failure. - Severe hepatic toxicity. - Life‑threatening hypersensitivity reactions. - Secondary malignancies: rare cases of leukemia.

What precautions apply to Hydroxycarbamide?

When prescribing Hydroxyurea, clinicians should consider several safety precautions.

- Monitor blood counts: regular CBC to detect myelosuppression. - Assess renal function: adjust use if impairment present. - Evaluate hepatic function: monitor liver enzymes. - Counsel on infection risk: advise prompt reporting of fever. - Avoid use in patients with known hypersensitivity to hydroxyurea. - Store at ambient temperature below 25°C: keep in original container, protect from moisture.

What does Hydroxycarbamide interact with?

Hydroxyurea can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid): - Antiretroviral protease inhibitors: may increase hydroxyurea toxicity. - Azathioprine: additive bone marrow suppression. - Live vaccines: risk of severe infection due to immunosuppression.

Moderate Interactions (Monitor Closely): - NSAIDs: may enhance renal toxicity. - Phenytoin: may reduce hydroxyurea plasma levels. - Allopurinol: may increase risk of hematologic toxicity.

Frequently asked questions

What is Hydroxyurea Medac used for?+
Hydroxyurea Medac contains hydroxycarbamide, an oral ribonucleotide reductase inhibitor indicated for the treatment of chronic myelogenous leukemia, sickle cell disease, and polycythemia vera. It works by slowing the growth of abnormal blood cells and, in sickle cell disease, by raising fetal hemoglobin levels, which reduces painful crises.
How does hydroxycarbamide work?+
Hydroxycarbamide inhibits the enzyme ribonucleotide reductase, which is essential for converting ribonucleotides to deoxyribonucleotides. This reduction limits DNA synthesis, leading to decreased proliferation of rapidly dividing cells such as malignant leukocytes and abnormal erythrocytes, and promotes fetal hemoglobin production in sickle cell disease.
What is the usual dose of Hydroxyurea Medac?+
The dosage of Hydroxyurea Medac is individualized and must be determined by a qualified prescriber based on the patient’s specific condition, laboratory values, and response to therapy. Dosing is typically started at a low level and adjusted according to clinical monitoring.
Is Hydroxyurea safe during pregnancy or breastfeeding?+
Safety data for hydroxycarbamide in pregnancy and lactation are limited. It is generally advised to avoid use during pregnancy unless the potential benefit justifies the risk, and breastfeeding is usually not recommended because the drug can be excreted in milk. Consultation with a specialist is essential.
How do I order Hydroxyurea Medac from GNH USA?+
To place an order, submit an enquiry on the product page at gnh-usa.com, specifying the required quantity. GNH USA works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details, and necessary import documentation.
How does Hydroxyurea compare with other treatments for sickle cell disease?+
Hydroxyurea is the only disease‑modifying oral therapy approved for sickle cell disease, whereas alternatives such as blood transfusions or newer gene‑editing approaches address symptoms or aim for curative intent. Hydroxyurea’s advantage lies in its oral administration and ability to increase fetal hemoglobin, though it requires regular monitoring.
What are the storage and handling requirements for Hydroxyurea Medac?+
Hydroxyurea Medac tablets should be stored at ambient temperature below 25 °C, kept in the original packaging, and protected from moisture and direct sunlight. Do not store in a refrigerator or freezer, and keep out of reach of children.
How is Hydroxyurea Medac administered?+
The medication is taken orally, usually with a glass of water. It may be taken with or without food, but consistency with regard to meals can help reduce gastrointestinal discomfort. Patients should follow the prescriber’s instructions regarding timing and any required fasting.
What are the most serious risks associated with Hydroxyurea Medac?+
The most critical risks include severe bone‑marrow suppression leading to aplastic anemia, life‑threatening infections due to neutropenia, renal or hepatic failure, and rare occurrences of secondary malignancies. Prompt reporting of fever, unusual bruising, or signs of organ dysfunction is essential.
Who should not use Hydroxyurea Medac?+
Hydroxyurea is contraindicated in individuals with known hypersensitivity to hydroxycarbamide, in patients with severe bone‑marrow failure, and in those receiving concurrent therapies that cause profound myelosuppression unless closely supervised. Pregnant women, unless benefits outweigh risks, should also avoid it.
