What is the most important information I should know about mercaptopurine
(Purinethol, Purixan)?

   You should not use mercaptopurine if you have ever used mercaptopurine
   or thioguanine (Tabloid) and they were not effective in treating
   your condition.

   Some people using mercaptopurine have developed a rare fast-growing
   type of lymphoma (cancer). This condition affects the liver,
   spleen, and bone marrow, and it can be fatal.

   Using mercaptopurine may also increase your risk of developing other
   types of cancer, such as skin cancer or uterine cancer.

   Call your doctor at once if you have symptoms of lymphoma, such as:
   fever, night sweats, weight loss, tiredness, feeling full after eating
   only a small amount, pain in your upper stomach, easy bruising or
   bleeding, dark urine, or jaundice (yellowing of the skin or eyes).

What should I discuss with my healthcare provider before taking
mercaptopurine (Purinethol, Purixan)?

   You should not use mercaptopurine if you are allergic to it, or if you
   have ever used mercaptopurine or thioguanine (Tabloid) and they were
   not effective in treating your condition.

   Some people using mercaptopurine have developed a rare fast-growing
   type of lymphoma (cancer). This condition affects the liver, spleen,
   and bone marrow, and it can be fatal. This has occurred mainly in
   teenagers and young adults using mercaptopurine or similar medicines to
   treat Crohn's disease or ulcerative colitis.

   However, people with autoimmune disorders (including rheumatoid
   arthritis, Crohn's disease, ankylosing spondylitis, and
   psoriasis) may have a higher risk of lymphoma. Talk to your doctor
   about your individual risk.

   Using mercaptopurine may also increase your risk of developing other
   types of cancer, such as skin cancer or uterine cancer. Ask your doctor
   about your specific risk.

   To make sure mercaptopurine is safe for you, tell your doctor if you
   have:
     * liver disease;
     * kidney disease;
     * an inherited condition in which your body cannot produce enough of
       the enzyme thiopurine methyltransferase (TPMT);
     * any type of viral, bacterial, or fungal infection; or
     * ulcerative colitis (treated with mesalamine,
       sulfasalazine, or similar medicines).

   Do not use mercaptopurine if you are pregnant. It could harm the unborn
   baby. Use effective birth control, and tell your doctor if you become
   pregnant during treatment.

   It is not known whether mercaptopurine passes into breast milk or if it
   could harm a nursing baby. You should not breast-feed while taking
   mercaptopurine.

How should I take mercaptopurine (Purinethol, Purixan)?

   Follow all directions on your prescription label. Your doctor may
   occasionally change your dose to make sure you get the best results. Do
   not take this medicine in larger or smaller amounts or for longer than
   recommended.

   Shake the oral suspension (liquid) well just before you measure a dose.
   Measure liquid medicine with the dosing syringe provided, or with a
   special dose-measuring spoon or medicine cup. If you do not have a
   dose-measuring device, ask your pharmacist for one.

   Use care when handling mercaptopurine oral suspension. The liquid can
   be dangerous if it gets in your eyes or on your skin. If this occurs,
   wash your skin with soap and water or rinse your eyes with water. Seek
   medical attention if you have redness, itching, or swelling even after
   rinsing off the medicine. Ask your doctor or pharmacist how to safely
   clean up an accidental spill.

   Mercaptopurine can lower blood cells that help your body fight
   infections and help your blood to clot. Your blood will need to be
   tested often. Your liver function may also need to be checked. Your
   cancer treatments may be delayed based on the results of these tests.

   Store at room temperature away from moisture and heat.

   symptoms.

What should I avoid while taking mercaptopurine (Purinethol, Purixan)?

   This medicine can pass into body fluids (urine, feces, vomit).
   Caregivers should wear rubber gloves while cleaning up a patient's body
   fluids, handling contaminated trash or laundry or changing diapers.

   linens separately from other laundry.

   Do not receive a "live" vaccine while using mercaptopurine, and avoid
   coming into contact with anyone who has recently received a live

   Live vaccines include measles, mumps, rubella
   (MMR), polio, rotavirus, typhoid, yellow fever,
   varicella (chickenpox), zoster (shingles), and nasal
   flu (influenza) vaccine.

What other drugs will affect mercaptopurine (Purinethol, Purixan)?
