GENERIC NAME: torsemide





  • Torsemide is used for the treatment of edema (water retention) due to congestive heart failure, kidney disease, chronic kidney failure, or liver disease.
  • Torsemide also is used alone or combined with other antihypertensive agents for the treatment of hypertension.
  • Torsemide should not be used in people who are allergic to it or to sulfonylureas to which it is related.
  • Torsemide should not be used in people who are unable to produce urine.
  • Torsemide should be used with caution in patients with liver disease with cirrhosis and ascites because sudden changes in fluid and electrolyte balance can cause hepatic coma.


Potent diuretics like torsemide can cause low blood levels of potassium, magnesium, sodium, and calcium. Additionally, fluid losses may lead to dehydration. The symptoms of dehydration may include:

Common side effects of disulfiram include:

Possible serious side effects of torsemide include:

Torsemide can cause dehydration and loss of potassium and other electrolytes. Low potassium levels (hypokalemia) can cause abnormal heart beats especially in people with heart disease or those taking digoxin (Lanoxin). Levels of potassium and other electrolytes should be monitored during treatment with torsemide.
