Torsemide is a diuretic used to reduce edema (swelling) from multiple causes such as heart failure, renal disease, or liver disease. Use of torsemide has been found to be effective for the treatment of edema associated with chronic renal failure.Torsemide tablets are also indicated for the treatment of high blood pressure (hypertension) alone or in combination with other antihypertensive agents.Torsemide is available under the following different brand names: Demadex. Torsemide is also used to treat high blood pressure (hypertension). High blood pressure adds to the work load of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

How should this medicine be used?

Torsemide comes as a tablet to take by mouth. It usually is taken once a day. To help you remember to take torsemide, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take torsemide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.Torsemide controls high blood pressure and edema but does not cure these conditions. Continue to take torsemide even if you feel well. Do not stop taking torsemide without talking to your doctor.
