Generic Name: sirolimus (sih RO lim us)
Brand Name: Rapamune
What is sirolimus?
Sirolimus weakens your body's immune system, to help keep it from "rejecting" a transplanted organ such as a kidney. Organ rejection happens when the immune system treats the new organ as an invader and attacks it.
Sirolimus is used with other medicines to prevent organ rejection after a kidney transplant.
Sirolimus is also given without other medicines to treat a rare lung disorder called lymphangioleiomyomatosis (lim-FAN-gee-oh-LYE-oh-MYE-oh-ma-TOE-sis). This disorder happens mostly in women and causes lung tumors that are not cancerous but can affect breathing.
Sirolimus may also be used for purposes not listed in this medication guide.
Sirolimus may cause your body to overproduce white blood cells. This can lead to cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure.
Call your doctor right away if you have: fever, flu symptoms, burning when you urinate, a new skin lesion, any change in your mental state, decreased vision, weakness on one side of your body, problems with speech or walking, or pain around your transplant.
