    • What is this medication and its most common uses?

      Rapamune is a medicine used to prevent organ rejection in people who have had a kidney transplant. Rapamune is also used to treat lymphangioleiomyomatosis (a rare lung disease that affects predominantly women of childbearing age). Rapamune is available as tablets and an oral solution.

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Your immune system is your body's defense against things that can cause infection and disease. Unfortunately, it cannot tell the difference between a harmful virus or bacteria and your new organ, so its natural response is to reject it. Rapamune works by stopping your immune system from rejecting your new organ.

      What are the beneficial effects of this medication and when should I begin to have results?


      Kidney Transplant: Rapamune has been shown to extend survival in people receiving a kidney transplant.

      Lymphangioleiomyomatosis: Rapamune may improve lung function during treatment.

      When: Though you may not feel a change in the way you feel, it is very important to keep receiving Rapamune as prescribed to prevent your body from rejecting your new organ.

      How do I know it is working?

      Your healthcare provider may order tests regularly to check the amount of Rapamune in your body and may ask you questions from time to time to assess how well this medication is working.
