Mercaptopurine

Mercaptopurine is a prescription medicine mainly used in the treatment of certain types of cancer, especially blood cancers like leukemia. It belongs to a group of medicines called chemotherapy or anticancer drugs. Mercaptopurine works by slowing down or stopping the growth of abnormal cells in the body, helping to control the disease and improve treatment outcomes.

This medicine is commonly used in children and adults as part of long-term cancer treatment plans, especially during maintenance therapy. In some cases, Mercaptopurine may also be prescribed for specific immune-related conditions, as it helps reduce overactive immune responses.

Mercaptopurine is usually taken orally and must be used exactly as prescribed by a doctor. Regular blood tests are required during treatment to monitor blood cell levels and liver function. While it is a powerful medicine, careful dosing and medical supervision help ensure safe and effective results.

When used correctly, Mercaptopurine plays a vital role in managing serious conditions and supporting long-term treatment success.
