Mercaptopurine Tablets are a prescription medicine that belongs to the class of antimetabolite chemotherapy drugs. They are primarily used in the treatment of certain types of cancer.

Here are the key details:

• Main Use:

  • Treats acute lymphoblastic leukemia (ALL), especially in maintenance therapy.

  • Sometimes used for other blood-related cancers or autoimmune conditions as prescribed by a doctor.

• How It Works: Mercaptopurine interferes with the synthesis of DNA and RNA in rapidly dividing cells, preventing cancer cells from multiplying and leading to cell death.

• Administration: Taken orally, usually once daily or as directed by the doctor. Dosage is individualized based on the patient’s condition, age, and response to treatment.

• Common Side Effects: Nausea, vomiting, loss of appetite, mild fatigue, diarrhea, or mouth sores.

• Serious Concerns:

  • Can cause bone marrow suppression, leading to low blood counts and increased risk of infections, anemia, or bleeding.

  • May cause liver toxicity or allergic reactions.

  • Long-term use may increase the risk of secondary cancers.

• Precautions:

  • Regular monitoring of blood counts and liver function is essential during treatment.

  • Patients should avoid exposure to infections due to reduced immunity.

  • Inform the doctor about all other medications, especially allopurinol, which can increase toxicity.

• Storage: Store at room temperature, away from moisture, heat, and direct sunlight.
