What is Hydroxyurea Capsule?
Hydroxyurea Capsule is a prescription medication primarily used for treating resistant chronic myeloid leukemia (CML). Manufactured by Zydus Cadila Pharma, it contains the active ingredient Hydroxyurea, which plays a critical role in managing certain blood disorders. This capsule is designed to help patients who have not responded adequately to conventional treatments and require an alternative therapeutic approach.
Hydroxyurea Capsule has been widely accepted in medical communities for its targeted action in slowing disease progression by interfering with the growth of abnormal blood cells. Available in various markets, including Canada, its effectiveness and safety profile make it a viable option under medical supervision.
Uses of Hydroxyurea Capsule
- Treatment of resistant chronic myeloid leukemia (CML), often after imatinib 100 mg or dasatinib 50 mg
- Management of certain myeloproliferative disorders, alongside supportive agents such as eltrombopag 25 mg
- Reduction of high white blood cell counts in leukemia patients
- Adjunct therapy in some cases of sickle cell anemia (off-label uses), where transfusion-related iron overload may need deferasirox 250mg
- Control of abnormal bone marrow activity
How Hydroxyurea Capsule Works
The mechanism of action of Hydroxyurea Capsule involves the inhibition of ribonucleotide reductase, an enzyme essential for DNA synthesis. By blocking this enzyme, Hydroxyurea interferes with the replication of rapidly dividing cells, including the malignant blood cells responsible for chronic myeloid leukemia.
This inhibition leads to decreased production of abnormal white blood cells, helping to restore a more balanced blood cell population and reduce disease symptoms. The medication specifically targets proliferative cells, thereby allowing for better management of resistant cases where traditional therapies may have limited success.
Benefits of Hydroxyurea Capsule

Hydroxyurea Capsule should be taken exactly as prescribed by a healthcare professional. The dosage depends on the patient's condition, weight, and response to treatment. Typically, it is administered orally once daily, with or without food.
It is important not to alter the dose or discontinue treatment without consulting your doctor. Regular monitoring of blood counts and overall health status is essential during therapy to adjust dosage if necessary and prevent potential complications.
