What is mercaptopurine?

Mercaptopurine is a chemotherapy drug of the antimetabolite, antineoplastic agent classes prescribed, along with other medications, to treat acute lymphocytic leukemia (also known as acute lymphoblastic or acute lymphatic leukemia). As a purine antagonist, it works by halting the growth of cancer cells. It may also be prescribed to treat other types of cancer, ulcerative colitis, or Crohn’s disease.

How do I take mercaptopurine?

Mercaptopurine is taken orally, once a day, with or without food. The amount and frequency of dosage will depend on the individual’s medical profile.
