Anti-rejection medicines

After your transplant (and sometimes before), in order to keep your body from rejecting your transplanted organ your doctor will prescribe anti-rejection or immunosuppressive medicines to suppress your immune system. These medicines are critical to the success of your transplant.

Taking all of your medicines as instructed may help you prevent rejection episodes:


  • Ensure that you take the right amount of each medicine you have been prescribed

  • Take every dose
    at the right time

  • Remember to take
    your medicines with
    or without food, as directed by your transplant team

  • Try not to miss
    a single dose

  • Notify your transplant team if you are taking other medicines

If you miss multiple doses, remember to call your transplant team right away.
