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 (e.g., 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 immediately 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 (e.g., fever, persistent sore throat).Who should not take sirolimus?
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.
Read the Medication Guide provided by your pharmacist before you start taking sirolimus and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth, usually once daily or as directed by your doctor. Swallow this medication whole. Do not crush, chew, or break the tablets.

However, you must choose one way (with food or without food) and always take this medication the same way so that your body always absorbs the same amount of drug. Consult your doctor or pharmacist for more details.

Other medications (e.g., antibiotics, immunosuppressants) may also be prescribed to help prevent infection in your body and to help prevent rejection of the transplanted organ. Take these additional medications exactly as prescribed by your doctor.
