Sirolimus - oral
Sirolimus - oral
Sirolimus lowers the body's ability to fight an infection/disease (immunosuppression). This may increase your risk of developing an infection or certain types of cancer (such as skin cancer, lymphoma). To reduce the risk of these serious side effects, take this medication at the lowest effective dose as directed by your doctor. Keep all medical and laboratory appointments.
Tell your doctor right away if you develop any of the following: unusual skin changes, change in the appearance/size of moles, unusual growths/lumps, swollen glands, night sweats, unexplained weight loss, signs of infection (such as sore throat that doesn't go away, fever).
Sirolimus is not recommended for the prevention of rejection of liver or lung transplants because it has rarely caused very serious (possibly fatal) liver/lung problems in those cases.
Sirolimus is used with other medications to prevent rejection of a kidney transplant. This medication belongs to a class of drugs known as immunosuppressants. It works by weakening your body's defense system (immune system) to help your body accept the new organ as if it were your own.
Sirolimus may also be used to treat a certain lung disease (lymphangioleiomyomatosis-LAM).
