Torsemide is used to reduce extra fluid in the body (edema) caused by conditions such as heart failure, liver disease, and kidney disease. This can lessen symptoms such as shortness of breath and swelling in your arms, legs, and abdomen.
Torsemide is a "water pill" (diuretic) that causes you to make more urine. This helps your body get rid of extra water and salt.
Take this medication by mouth as directed by your doctor, with or without food, usually once daily. It is best to avoid taking this medication within 4 hours of your bedtime to prevent having to get up to urinate.
Dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than directed.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day as directed. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Generally, it may take 4-6 weeks, and sometimes up to 12 weeks, before the full blood pressure-lowering effect is seen. Do not stop taking this medication without consulting your doctor.
Cholestyramine and colestipol can decrease the absorption of torsemide. If you are taking either of these drugs, separate the timing of each dose from torsemide by at least 2 hours.
Tell your doctor if your condition does not improve or if it worsens. If you are taking this medication to control high blood pressure, tell your doctor if your blood pressure readings remain high or increase.
