What is the most important information I should know about temsirolimus?
You should not use temsirolimus if you have severe liver disease.
What is temsirolimus?
Temsirolimus is used to treat cancer of the kidneys, also called renal cell carcinoma.
Temsirolimus may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before receiving temsirolimus?
You should not use temsirolimus if you have severe liver disease.
Tell your doctor if you have ever had:
- liver disease;
- kidney disease;
- high cholesterol or triglycerides (a type of fat in the blood);
- diabetes;
- a head injury or brain tumor; or
- an allergy to temsirolimus or sirolimus (Rapamune).
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 temsirolimus. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using temsirolimus.
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 temsirolimus given?
Temsirolimus is given as an infusion into a vein. A healthcare provider will give you this injection.
Temsirolimus 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 temsirolimus.
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 temsirolimus.
What happens if I miss a dose?
Call your doctor if you miss an appointment for your temsirolimus injection.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include breathing problems, confusion, seizure, or bloody stools.
What should I avoid while receiving temsirolimus?
Grapefruit may interact with temsirolimus and lead to unwanted side effects. Avoid the use of grapefruit products.
Do not receive a "live" vaccine while using temsirolimus. The vaccine may not work as well and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
What are the possible side effects of temsirolimus?
Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).
Some side effects may occur during the injection. Tell your caregiver right away if you feel dizzy, warm, tingly, light-headed, or short of breath.
Call your doctor at once if you have:
- cough, chest pain, wheezing, trouble breathing;
- stomach pain, bloody or tarry stools;
- pain or burning when you urinate, blood in your urine;

- nausea, vomiting, stomach pain, loss of appetite;
- swelling;

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What other drugs will affect temsirolimus?
Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
Tell your doctor about all your current medicines. Many drugs can affect temsirolimus, especially:
- sunitinib;
- St. John's Wort;
- an antibiotic or antifungal medicine;
- an antidepressant;
- antiviral medicine to treat hepatitis C or HIV/AIDS;
- a blood thinner (warfarin, Coumadin, Jantoven);
