SN instructed that Torsemide is a loop diuretic. It works by making the kidney eliminate larger amounts of electrolytes ( especially sodium and potassium salts ) and water than normal ( diuretic effect ). It is used to treat edema ( swelling ) associated with heart, kidney, or liver failure, or with conditions in which there is excess body water. It is also used alone or with other medicines to treat high blood pressure. Torsemide may increase the amount of urine or cause you to urinate more often when you first start taking it. To keep this from disturbing your sleep, try to take your dose before 6 pm. If you also take cholestyramine, do not take it within 4 hours before or after taking torsemide. may cause dizziness, lightheadedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects. Torsemide may affect your blood sugar. Check blood sugar levels closely.
