Hydroxyurea Tablets are a medicine used to treat certain blood disorders and cancers. They belong to a class of drugs called antineoplastic (chemotherapy) and antimetabolite agents.

Here are the key details:

• Composition: Each tablet contains Hydroxyurea, commonly in strengths such as 500 mg or 1000 mg.

• Dosage Form: Oral tablets, usually taken once daily or as prescribed by a doctor, with or without food.

• Mode of Action:

  • Hydroxyurea interferes with DNA synthesis by inhibiting the enzyme ribonucleotide reductase.

  • This slows the growth and division of rapidly dividing cells, such as cancer cells or abnormal blood cells.

• Uses:

  • Chronic myeloid leukemia (CML) and other types of leukemia.

  • Polycythemia vera – to reduce excessive red blood cell production.

  • Sickle cell anemia – to reduce the frequency of painful crises and need for blood transfusions.

  • Occasionally used in other cancers or blood disorders as prescribed by a doctor.

• Treatment Goal: To control abnormal cell growth, manage blood cell counts, and reduce complications related to certain cancers or blood disorders.

• Side Effects:

  • Common: nausea, vomiting, loss of appetite, diarrhea, mild hair thinning, skin rash.

  • Less common/serious: bone marrow suppression (low blood counts), increased risk of infections, mouth sores, liver or kidney function changes, allergic reactions.

• Precautions:

  • Regular monitoring of blood counts, liver, and kidney function is essential.

  • Use protective measures to avoid infections due to lowered immunity.

  • Avoid pregnancy or breastfeeding during treatment; effective contraception is recommended.

  • Inform the doctor about other medications or medical conditions to prevent interactions.

Hydroxyurea is effective because it targets rapidly dividing cells, making it useful for managing certain cancers and blood disorders, while helping reduce complications in conditions like sickle cell anemia.
