This medication is known as a diuretic (the same kind of drug as a "water pill"). It helps your body get rid of extra water by increasing the amount of urine you make. Getting rid of extra water decreases the strain on your heart and blood vessels, thereby lowering high blood pressure and reducing your risk of strokes, heart attacks, and kidney problems. This effect can also improve symptoms such as trouble breathing and swelling (edema). This injectable form of torsemide is used when the drug cannot be taken by mouth or when extra water must be removed quickly, especially in patients with severe medical conditions.
This medication is given by injection into a vein as directed by your doctor, usually once daily. Torsemide may be slowly injected over 2 minutes or given by continuous infusion (an IV). Dosage is based on your medical condition and response to treatment.
