Descriptions


Torsemide belongs to the group of medicines called loop diuretics. Torsemide is given to help reduce the amount of water in the body in certain conditions, such as congestive heart failure, severe liver disease (cirrhosis), or kidney disease. It works by acting on the kidneys to increase the flow of urine.

Torsemide is also used to treat high blood pressure (hypertension). High blood pressure adds to the work load of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

Torsemide is available only with your doctor's prescription.

This product is available in the following dosage forms:

  • Tablet

For patients taking this medicine for high blood pressure:

  • In addition to the use of the medicine your doctor has prescribed, treatment for your high blood pressure may include weight control and care in the types of foods you eat, especially foods high in sodium. Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.

Precautions

It is important that your doctor check your progress at regular visits to make sure that this medicine is working properly.

This medicine may cause a loss of potassium from your body:

  • To help prevent this, your doctor may want you to:
    • eat or drink foods that have a high potassium content (for example, orange or other citrus fruit juices), or
    • take a potassium supplement, or
    • take another medicine to help prevent the loss of the potassium in the first place.
  • It is very important to follow these directions. Also, it is important not to change your diet on your own. This is more important if you are already on a special diet (as for diabetes) or if you are taking a potassium supplement or a medicine to reduce potassium loss. Extra potassium may not be necessary and, in some cases, too much potassium could be harmful.

To prevent the loss of too much water and potassium, tell your doctor if you become sick, especially with severe or continuing nausea and vomiting or diarrhea.

Before having any kind of surgery (including dental surgery) or emergency treatment, make sure the medical doctor or dentist in charge knows that you are taking this medicine.

Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position. This is more likely to occur in the morning. Getting up slowly may help. When you get up from lying down, sit on the edge of the bed with your feet dangling for 1 or 2 minutes. Then stand up slowly. If the problem continues or gets worse, check with your doctor.

The dizziness, lightheadedness, or fainting is also more likely to occur if you drink alcohol, stand for long periods of time, or exercise, or if the weather is hot. While you are taking this medicine, be careful to limit the amount of alcohol you drink. Also, use extra care during exercise or hot weather or if you must stand for long periods of time.

For diabetic patients:

  • This medicine may affect blood sugar levels. While you are using this medicine, be especially careful in testing for sugar in your blood or urine.

For patients taking this medicine for high blood pressure:

  • Do not take other medicines unless they have been discussed with your doctor. This especially includes over-the-counter (nonprescription) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.
