Azathioprine is an anti-inflammatory / immunosuppressant or DMARD
(disease-modifying antirheumatic drug). Drugs in this category can
decrease joint damage and disability. Azathioprine is used to treat a
number of inflammatory disorders, including rheumatoid arthritis, lupus,
inflammatory myositis, vasculitis and inflammatory bowel disease. Azathioprine also inhibits the
immune response that causes rejection of kidney transplants. Imuran is normally taken with
other drugs (particularly corticosteroids), such as Prednisolone.
Two well known brands of Azathioprine are made by GSK, labelled Imuran and Zymurine,
(according to the country). Other brand names and generics are also available (see below).

Azathioprine Side Effects
The most common side effects of azathioprine involve the gastrointestinal tract and blood cells.
It has been noted that up to 15 percent of users experience nausea and vomiting, sometimes
with abdominal pain or diarrhea. It has therefore been recommended that taking athazioprine
twice daily instead of all at once, or taking it after food, may help avoid these problems.
Less common: azathioprine has been associated with liver test abnormalities, hepatitis
(inflammation of the liver), pancreatitis (inflammation of the pancreas behind the stomach that
can cause abdominal pain). Azathioprine also can lower infection-fighting white blood cells.
Azathioprine precautions and drug interactions
When Azathioprine is used long-term (particularly in those with a prior history of treatment with
other immunosuppressants such as Cytoxan, Leukeran and Alkeran), it can cause an increase
in cancer risk. Azathioprine can also reduce the sperm count in males and impair fertility.
The following drugs can adversely interact with Azathioprine:
The gout medication Allopurinol (Zyloprim) can increase the toxicity of azathioprine.
ACE-inhibitors used to treat high blood pressure (example Accupril and Vasotec) can increase
the risk of lowering white blood cells which can also increases the risk of serious infections.
This is NOT a full list of all possible drug interactions : ALWAYS inform your doctor about
ALL prescription and non prescription medications that you use or have used.
