Generic Name: sirolimus (sih RO lim us)
Brand Name: Rapamune
What is Rapamune (sirolimus)?
Sirolimus lowers your body's immune system. The immune system helps your body fight infections. The immune system can also fight or "reject" a transplanted organ such as a liver or kidney. This is because the immune system treats the new organ as an invader.
Sirolimus is given in a combination treatment with cyclosporine and a steroid medicine to prevent your body from rejecting a transplanted kidney.
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.

You should not use sirolimus if you have ever had a lung transplant or liver transplant.
Sirolimus can lower blood cells that help fight infection, and may lead to serious conditions including cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure.
Call your doctor right away if you have signs of infection (fever, chills, body aches), a change in your mental state, or problems with vision, speech, or walking.

How should I take Rapamune (sirolimus)?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Sirolimus can lower blood cells that help fight infection, and may cause you to produce too much of a certain type of white blood cell. This can lead to serious conditions including cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure. Your blood will need to be tested often. Your kidney function will also need to be tested. Your sirolimus dosing schedule may be delayed based on the results of these tests.
You should not stop using sirolimus without your doctor's advice. Stopping suddenly could make your condition worse.
Store sirolimus tablets at room temperature, away from heat, moisture, and light.
Store sirolimus liquid in the refrigerator. Do not freeze. You may notice a slight haze to the liquid after it has been refrigerated. This haze will not affect the medication, and should disappear when the liquid reaches room temperature.
