Uses for Demadex

Torsemide is used to treat fluid retention (edema) and swelling caused by congestive heart failure, liver disease, and kidney disease. It is part of a group of medicines called loop diuretics (water pills). This medicine works by acting on the kidneys to increase urine flow.

Torsemide is also used alone or with other medicines to treat high blood pressure (hypertension). High blood pressure makes the heart and arteries work harder. If it lasts a long time, it can cause the heart and arteries to not work properly. This can damage the blood vessels in the brain, heart, and kidneys, leading to a stroke, heart failure, or kidney failure. High blood pressure may also raise the risk of heart attacks. Controlling blood pressure may help reduce these problems.

This medicine is available only with your doctor's prescription.

Precautions while using Demadex

It is very important that your doctor check your progress at regular visits to make sure Demadex (Oral) is working properly. Blood and urine tests may be needed to check for unwanted effects.

Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help. If the problem continues or gets worse, check with your doctor.

Demadex (Oral) may make you dizzy or drowsy. Do not drive or do anything else that could be dangerous until you know how Demadex (Oral) affects you. Sit or lie down if you feel dizzy. Stand up carefully.

Demadex (Oral) may cause you to lose more potassium from your body than normal (hypokalemia). This is more likely to occur if you have liver disease (e.g., cirrhosis), or if you are using Demadex (Oral) together with steroids (cortisone-like medicines), adrenocorticotropic hormone (ACTH), large amounts of licorice, or laxatives for a long time. Tell your doctor if you become sick with severe or continuing nausea, vomiting, or diarrhea, and drink fluids to prevent getting dehydrated. Check with your doctor right away if you have dry mouth, increased thirst, muscle cramps, or nausea or vomiting.

Check with your doctor right away if you have a sudden decrease in hearing or loss of hearing. You may also have dizziness or ringing in the ears. Tell your doctor if you have a feeling of constant movement of self or surroundings or a sensation of spinning.

Demadex (Oral) may cause an increase in blood sugar levels. If you are diabetic and notice a change in the results of your blood or urine sugar tests, check with your doctor.

Make sure any doctor or dentist who treats you knows that you are using Demadex (Oral). Demadex (Oral) may affect the results of certain medical tests.

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