Rapamune

Rapamune prevents organ rejection in those patients who have received a kidney transplant. Take your dose of Rapamune the same way, either with or without food.

Rapamune Overview

Updated: 

Rapamune is a prescription medication used to prevent kidney transplant rejection.  Rejection is when your body’s immune system recognizes the new organ as a “foreign” threat and attacks it. Rapamune belongs to a group of drugs called immunosuppressants, which prevent the immune system from attacking the transplanted kidney. 

This medication comes in tablet and liquid forms.  Rapamune is taken once a day. The tablets should be swallowed whole, with or without food.  The liquid should be kept refrigerated and mixed with water or orange juice immediately before it is taken.

Common side effects of Rapamune include high blood pressure, pain, diarrhea and headache.

  • Serious allergic reactions. Tell your doctor or get medical help right away if you get any of following symptoms of an allergic reaction:
    • swelling of your face, eyes, or mouth
    • trouble breathing or wheezing
    • throat tightness
    • chest pain or tightness
    • feeling dizzy or faint
    • rash or peeling of your skin
  • Swelling (edema). Fluid may collect in your hands and feet and in various tissues of your body, including in the sac around your heart or lungs. Call your doctor if you have trouble breathing.
  • Poor wound healing. Rapamune may cause your wounds to heal slowly or not heal well. Tell your doctor if you have any redness or drainage, your wound does not heal, or the wound opens up.
  • Increased levels of cholesterol and triglycerides (lipids or fat) in your blood. Your doctor should do blood tests to check your lipids during treatment with Rapamune. Your doctor may prescribe treatment with diet, exercise, or medicine if your lipid levels are too high. During treatment with Rapamune, your blood levels of cholesterol and triglycerides may remain high even if you follow your prescribed treatment plan.
  • Effects on kidney function. When Rapamune is taken with cyclosporine (Gengraf, Neoral, Sandimmune), the function of your transplanted kidney may be affected. Your doctor should regularly do tests to check your kidney function while you are taking Rapamune with cyclosporine (Gengraf, Neoral, Sandimmune).
  • Increased protein in your urine. Your doctor may regularly test your urine protein.
  • Increased risk for viral infections.
    • Certain viruses can live in your body and cause active infections when your immune system is weak. BK virus can affect how your kidney works and cause your transplanted kidney to fail.
    • A certain virus can cause a rare serious brain infection called Progressive Multifocal Leukoencephalopathy (PML). PML usually causes death or severe disability. Call your doctor right away if you notice any new or worsening medical problems such as:
      • confusion
      • sudden change in thinking, walking, strength on one side of your body
      • other problems that have lasted over several days.
  • Lung or breathing problems. This can sometimes lead to death. Tell your doctor if you have a new or worsening cough, shortness of breath, difficulty breathing or any new breathing problems. Your doctor may need to stop Rapamune or lower your dose.
  • Blood clotting problems. When Rapamune is taken with cyclosporine or tacrolimus, you may develop a blood clotting problem. Tell your doctor if you get any unexplained bleeding or bruising.

Common side effects with Rapamune include:

  • high blood pressure
  • pain (including stomach and joint pain)
  • diarrhea
  • headache
  • fever

Rapamune FDA Warning

BOX WARNING: IMMUNOSUPPRESSION, USE IS NOT RECOMMENDED IN LIVER OR LUNG TRANSPLANT PATIENTS

  • Increased susceptibility to infection and the possible development of lymphoma and other malignancies may result from immunosuppression

Increased susceptibility to infection and the possible development of lymphoma may result from immunosuppression. Only physicians experienced in immunosuppressive therapy and management of renal transplant patients should use Rapamune. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient.

  • The safety and efficacy of Rapamune as immunosuppressive therapy have not been established in liver or lung transplant patients, and therefore, such use is not recommended 
  • Liver Transplantation – Excess Mortality, Graft Loss, and Hepatic Artery Thrombosis (HAT)

The use of Rapamune in combination with tacrolimus was associated with excess mortality and graft loss in a study in de novo liver transplant patients. Many of these patients had evidence of infection at or near the time of death.

In this and another study in de novo liver transplant patients, the use of sirolimus in combination with cyclosporine or tacrolimus was associated with an increase in HAT; most cases of HAT occurred within 30 days post-transplantation and most led to graft loss or death.

  • Lung Transplantation – Bronchial Anastomotic Dehiscence

Cases of bronchial anastomotic dehiscence, most fatal, have been reported in de novo lung transplant patients when Rapamune has been used as part of an immunosuppressive regimen
