WHAT IS TORSEMIDE AND HOW DOES IT WORK?
Torsemide is a diuretic used to reduce oedema (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 oedema 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.

Effects of Drug Abuse
- No information available
- See “What Are Side Effects Associated with Using Torsemide?”
- See “What Are Side Effects Associated with Using Torsemide?”
- Use with caution in diabetes mellitus, fluid or electrolyte imbalance (hypokalemia, hyponatremia), hyperglycemia, hyperlipidemia, hyperuricemia or gout, severe liver disease with cirrhosis and ascites
- Use with caution in cirrhosis; avoid changes in fluid and electrolyte balance and acid-base status, which may lead to hepatic encephalopathy
- Monitor fluid status and renal function to prevent azotemia, oliguria, and reversible increases in blood urea nitrogen(BUN) and creatinine
- Excessive diuresis may cause potentially symptomatic dehydration, blood volume reduction and hypotension and worsening renal function, including acute renal failure particularly in salt-depleted patients or those taking renin-angiotensin-aldosterone inhibitors; worsening of renal function can also occur with concomitant use of nephrotoxic drugs (e.g., aminoglycosides, cisplatin, and nonsteroidal anti-inflammatory drugs [NSAIDs]); monitor volume status and renal function periodically
- Can cause potentially symptomatic hypokalemia, hyponatremia, hypomagnesemia, hypocalcemia, and hypochloremic alkalosis; therapy can cause an increase in blood glucose levels and hyperglycemia; asymptomatic hyperuricemia can occur and gout may rarely be precipitated; monitor serum electrolytes and blood glucose periodically
- Tinnitus and hearing loss (ototoxicity; usually reversible) have been observed with loop diuretics; higher than recommended doses, severe renal impairment, and hypoproteinemia, appears to increase the risk of ototoxicity
Pregnancy and Lactation
- There are no available data on use of torsemide in pregnant women and the risk of major birth defects or miscarriage. However, in pregnant rats and rabbits administered 50 and 6.8 times the human dose, respectively, decreases in body weight, decreased fetal resorption and delayed fetal ossification were observed
- There are no data regarding the presence of torsemide in human milk or effects on the breastfed child
- Diuretics can suppress lactation
- Consult your doctor before breastfeeding
