Description

What is Imuran?

Imuran is an oral tablet made up of an immunosuppressant drug called azathioprine. We carry the brand choice and generic alternative of this medication in 25mg and 50mg!

What is Imuran used for? How does it work?

Imuran is used mostly commonly for two different conditions associated with the immune system. Imuran is used in the prevention of the body rejecting a kidney following a kidney transplant and for the treatment of rheumatoid arthritis.

After a kidney transplant, your immune system may sense your new kidney as a foreign tissue and because of that, may try to reject it and make antibodies try to kill the new organ. Imuran (azathioprine) is effective at preventing the rejection of a new kidney due to its ability to temporarily weaken the immune system until your body realizes the organ is beneficial and is no longer recognized as a foreign tissue.

Rheumatoid arthritis is when your immune system “malfunctions” and begins to attack healthy tissue of the body. This causes inflammation within the lining of your joints, resulting in red, warm, swollen and very painful joints. Imuran (azathioprine) is effective in the treatment of rheumatoid arthritis due to its ability to temporarily weaken the immune system to prevent further damage to your joints.
