Temsirolimus (Intravenous)

Temsirolimus is an intravenous drug often used therapeutically with other treatments to treat cancer.


In cases of kidney cancer, Temsirolimus, commonly branded and sold as Torisel, is used to combat the growth and spread of cancer cells. Growth of carcinoma in renal cells can slowed or halted by the use of Temsirolimus, which interferes with the growth hormones and allows the tumor to be destroyed naturally by the body.

Temsirolimus is given intravenously, in a solution form that is injected into a vein. It is often given under doctor supervision, and dosage is determined from patient to patient. It is not manufactured generically, and primarily used to treat kidney cancer. It can be used in other fashions, but only specifically with doctor recommendation.

Temsirolimus may cause side effects, and should be administered and used responsibly to avoid serious discomfort. If persistent or painful side effects occur, contact your doctor or healthcare provider immediately. Interactions may occur while using Temsirolimus in tandem with other medications. List any and all in-use drugs beforehand, and inform your doctor before taking anything during the course of your treatment.

Do not use Temsirolimus if you have experienced allergic reactions to any of the active or inactive ingredients in the drug. Temsirolimus should only be used with a doctor's recommendation and approval, and under/overdosing may result in complications or negative results.

To reduce side effects or discomfort while using Temsirolimus, practice a strict regimen of self care. Stay hydrated and drink water often, eat often and nutritiously, avoid exposure to strong sun, and keep track of any and all side effects you experience during treatment. Stay in contact with your doctor, schedule frequent check-ups, and contact medical authorities if you believe you are experiencing serious side effects.

Temsirolimus is a targeted therapy designed to slow and eliminate the spread of cancer before it becomes life threatening. Despite the risks and possible side effects, the benfits of treatment far outweigh those of an untreated lifestyle. Talk to your doctor if you think Temsirolimus may help you.
