What is the most important information I should know about temsirolimus?
You should not use temsirolimus if you have severe liver disease.
What should I discuss with my healthcare provider before receiving temsirolimus?
You should not use temsirolimus if you are allergic to it, or if you have:
severe liver disease.
To make sure temsirolimus is safe for you, tell your doctor if you have ever had:
high cholesterol or triglycerides (a type of fat in the blood);
a head injury, stroke, or brain tumor; or
an allergy to sirolimus (Rapamune).
Temsirolimus can harm an unborn baby. Use effective birth control to prevent pregnancy while you are using this medicine, whether you are a man or a woman. Temsirolimus use by either parent may cause birth defects.
Keep using birth control for at least 3 months after your last dose of temsirolimus. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using temsirolimus.

How is temsirolimus given?
Temsirolimus is injected into a vein through an IV. You will receive this injection in a clinic or hospital setting. Temsirolimus must be given slowly, and the IV infusion can take up to 60 minutes to complete.
Temsirolimus is usually given once each week unless your cancer progresses or you have serious side effects from this medicine.
You may be given medication to prevent certain side effects while you are receiving temsirolimus.
Temsirolimus can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your kidney function may also need to be tested. Your cancer treatments may be delayed based on the results of these tests.
If you need surgery, tell the surgeon ahead of time that you are using temsirolimus.
