What is Torisel?
Torisel (temsirolimus) is a cancer medicine that interferes with the growth and spread of cancer cells in the body.
Torisel is used to treat cancer of the kidneys, also called renal cell carcinoma.
Torisel may also be used for purposes not listed in this medication guide.
You should not use Torisel if you are allergic to temsirolimus or if you have severe liver disease. Do not use Torisel if you are pregnant. It could harm the unborn baby. Use an effective form of birth control while you are using this medication and for at least 3 months after your treatment ends.
Before you receive Torisel, tell your doctor if you have liver disease, high cholesterol, diabetes, an allergy to sirolimus (Rapamune), or a history of head injury, stroke, or brain tumor.
Temsirolimus can lower blood cells that help your body fight infections. Your blood may need to be tested often. Avoid being near people who are sick or have infections. Do not receive a live vaccine. Tell your doctor at once if you develop signs of infection.
There are many other drugs that can interact with temsirolimus. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor. Keep a list of all your medicines and show it to any healthcare provider who treats you.

Before taking this medicine
You should not use Torisel if you have severe liver disease.
To make sure Torisel is safe for you, tell your doctor if you have ever had:
high cholesterol or triglycerides (a type of fat in the blood);
Both men and women using this medicine should use effective birth control to prevent pregnancy. Temsirolimus can harm an unborn baby or cause birth defects if the mother or father is using this medicine.
Keep using birth control for at least 3 months after your last dose of Torisel. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using Torisel.
This medicine may affect fertility (ability to have children) in both men and women. However, it is important to use birth control to prevent pregnancy because temsirolimus can harm an unborn baby.
You should not breastfeed while using this medicine and for at least 3 weeks after your last dose.
How is Torisel given?
Torisel is given as an infusion into a vein. A healthcare provider will give you this injection.
Torisel is usually given once each week unless your cancer progresses or you have serious side effects from this medicine. This medicine must be given slowly, and the infusion can take up to 60 minutes to complete.
You may be given other medication to prevent an allergic reaction to Torisel.
You may need frequent medical tests to be sure this medicine is not causing harmful effects. Your cancer treatments may be delayed based on the results.
If you need surgery, tell the surgeon ahead of time that you are using Torisel.
