Mercaptopurine is a chemotherapy drug used to treat acute lymphoblastic leukemia (ALL) in adults and children. ALL is a type of cancer that causes an overproduction of lymphocytes. Lymphocytes produced by cancerous bone marrow cells are immature and do not function properly. Eventually, normal lymphocytes are crowded out by the immature lymphocytes.
Mercaptopurine is typically prescribed with other drugs as part of a chemotherapy maintenance treatment regimen. Cancer maintenance therapy consists of one or more drugs that are taken after radiation or chemotherapy. Maintenance therapy is intended to prevent a relapse of cancer.
Mercaptopurine slows and stops the growth of cancer cells. It works as a purine antimetabolite to disrupt the production of DNA, a vital part of cancer cell growth.
Mercaptopurine is usually taken as a tablet once per day.
Common side effects of Mercaptopurine include, but are not limited to, nausea, vomiting, diarrhea, weakness, and rash.
Mercaptopurine may cause low red and white blood cell counts, including anemia, leukopenia, and thrombocytopenia. Low white blood cell counts can increase the risk of infection. Seek immediate medical attention if you experience signs or symptoms of an allergic reaction, such as hives, swelling of the throat, or trouble breathing.
This is not a complete list of side effects. Tell your doctor about other medical conditions you may have or other medications you may be taking. Seek medical advice on other possible side effects, warnings, and precautions associated with Mercaptopurine. You can report negative side effects to the FDA.
