Azathioprine (Imuran®)


Imuran® is an immunosuppressive medicine that helps prevent organ rejection.


The dose we prescribe for you is based on your weight and white blood cell count.

Adults: Tablets are available in 50mg size which can easily be broken in half.
Children: Imuran can be taken in the same 50mg tablet form, or in a liquid formulation of 10mg/cc.


At bedtime with your other nighttime medications.


Certain medications, such as allopurinol, can increase the effects of Imuran and further deplete your white blood cell count. Remember to always contact the transplant team before taking any new medication.
