Uses
What is torsemide used for?
Torsemide is a diuretic, also called a water pill, that is commonly used to reduce edema (fluid retention) caused by the following conditions.
- Congestive heart failure, which is a condition where the heart is not pumping as well as it should
- Liver disease, such as cirrhosis, which can lead to a buildup of fluid in the abdomen (ascites)
- Kidney disease, including protein in the urine (nephrotic syndrome)
Torsemide may also be used to treat high blood pressure (hypertension).
Torsemide may also be used for other conditions as determined by your healthcare provider.

What are the serious side effects of torsemide?
While less common, the most serious side effects of torsemide are described below, along with what to do if they happen.
Low Blood Pressure with Worsening Kidney Function. Water loss from torsemide can lower your blood pressure too much and cause dehydration. Both may lead to problems that are more serious than light-headedness. Poor blood flow to important organs such as your kidneys can occur, especially if you are elderly. Drink enough water to stay hydrated, especially if you have excess sweating, vomiting, or diarrhea. Get out of bed or from a seated position slowly. Tell your healthcare provider right away if you have any of the following symptoms.
- Dizziness, feeling lightheaded, or fainting
- Confusion
- Feeling weak or tired
- Reduced need to pee
- Sudden weight gain
- Increased thirst
- Dark or strong-smelling pee
- Dry mouth
- Sunken eyes
- Headache
- Fast heartbeat
Electrolyte Changes and Increased Blood Sugar. Torsemide may increase your blood sugar (glucose) levels and cause changes to the levels of certain minerals in your body, called electrolytes. For example, it may cause low potassium levels (hypokalemia), low sodium levels (hyponatremia), low magnesium levels (hypomagnesemia), low calcium levels (hypocalcemia), low chloride levels (hypochloremia), or high glucose levels (hyperglycemia). These changes can be serious. Your healthcare provider will do bloodwork to check your glucose and electrolyte levels, especially if you take certain other medicines. Keep your appointments to have your blood checked. Call your healthcare provider if you have any of the following symptoms of electrolyte changes.
- Weakness
- Unusual tiredness
- Muscle cramps or twitching
- Constipation
- Nausea, vomiting, or loss of appetite
- Dizziness
- Restlessness or irritability
- Difficulty breathing
- Confusion or decreased alertness
- Abnormal heart rhythm
- Seizures
Hearing Loss. Torsemide may be associated with hearing loss, which is also called ototoxicity. Tell your healthcare provider right away if you have hearing loss or if you hear a ringing or roaring sound in your ears while taking torsemide.
Severe Allergic Reactions. Torsemide may cause allergic reactions, which can be serious. Stop using torsemide and get help right away if you have any of the following symptoms of a serious allergic reaction.
- Breathing problems or wheezing
- Racing heart
- Fever or general ill feeling
- Swollen lymph nodes
- Swelling of the face, lips, mouth, tongue, or throat
