What IMURAN is used for

IMURAN contains azathioprine as the active ingredient. Azathioprine belongs to a group of medicines called immunosuppressants.
IMURAN is used to help prevent the rejection of a transplanted organ such as a kidney, liver or heart. It works by suppressing the body's immune defence system.
IMURAN can also be used to treat other diseases called autoimmune diseases where your immune system is reacting against your own body. These may include:
severe rheumatoid arthritis
systemic lupus erythematosus
chronic active hepatitis
certain skin, muscle, and blood diseases.
IMURAN is usually taken in combination with other medicines such as corticosteroids or other immunosuppressive drugs.
Ask your doctor if you have any questions about why IMURAN has been prescribed for you.
Your doctor may have prescribed it for another purpose.
This medicine is only available with a doctor's prescription.
There is no evidence that it is addictive.
