It is very important that your doctor check your progress at regular visits to see if the medicine is working properly. Blood tests may be needed to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Men and women should use an effective form of birth control during treatment with temsirolimus and for at least 3 months after the last dose. If you think you have become pregnant while using this medicine, tell your doctor right away.

Temsirolimus may cause serious types of allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash; itching; swelling of the face, tongue, and throat; trouble with breathing; or chest pain after you get the injection.

This medicine may cause flushing, headaches, and lightheadedness or faintness, while you are receiving the injection or within 24 hours after you receive it. Check with your doctor or nurse right away if you have any of these symptoms.

This medicine may increase the amount of sugar in your blood. Check with your doctor right away if you have increased thirst or urination. Your doctor may give you insulin or other medicines that can lower the amount of sugar in your blood.

While you are being treated with temsirolimus, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. Temsirolimus may lower your body's resistance and there is a chance you might get the infection the vaccine is meant to prevent. In addition, other persons living in your household should not get live vaccines (eg, nasal flu virus vaccine, measles, mumps, or rubella vaccine, oral polio vaccine, BCG, yellow fever vaccine, varicella vaccine, or TY21a typhoid vaccine). Try to avoid being around persons who have received live vaccines. Do not get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.

Treatment with temsirolimus may also increase the chance of getting other infections. If you can, avoid people with colds or other infections. If you think you are getting a cold or other infection, check with your doctor.

This medicine may cause a serious lung problem. Check with your doctor immediately if you are having tightness in the chest, shortness of breath, difficulty with breathing, or wheezing.

Temsirolimus may increase your cholesterol and fats in the blood. If this condition occurs, your doctor may give you a medicine to lower the cholesterol and fats.

Check with your doctor right away if you start having severe abdominal or stomach burning, cramps, or pains; bloody or black, tarry stools; diarrhea; fever; nausea; or vomiting of material that looks like coffee grounds. These could be symptoms of a serious bowel problem.

This medicine may increase your chance of having acute kidney disease that is not related to the worsening of your kidney cancer. Talk to your doctor about this risk.

This medicine may affect the way your body heals from cuts and wounds. Make sure any doctor who treats you knows that you are using this medicine. You may need to stop using this medicine several weeks before and after having surgery.

Grapefruit and grapefruit juice may increase the effects of temsirolimus by increasing the amount of medicine in your blood. You should not eat grapefruit or drink grapefruit juice while receiving this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's Wort) or vitamin supplements.
