A contraindication is a condition or factor that serves as a reason to withhold a certain medical treatment due to the harm that it would cause the patient. It’s crucial to consider these before taking Mercaptopurine:

• Liver disease: Mercaptopurine is processed by the liver, and if the liver function is impaired, the drug can accumulate in the body, leading to toxicity.
• Bone marrow suppression: Mercaptopurine can cause a decrease in the production of blood cells, exacerbating any existing conditions that suppress bone marrow function.
• Hypersensitivity to Mercaptopurine: If you’ve had an allergic reaction to Mercaptopurine in the past, it’s contraindicated due to the risk of a severe allergic reaction.
