Demadex

GENERIC NAME(S): TORSEMIDE

Uses

Torsemide is used to reduce extra fluid in the body (edema) caused by conditions such as heart failure, liver disease, and kidney disease. This can lessen symptoms such as shortness of breath and swelling in your arms, legs, and abdomen.

This drug is also used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

Torsemide is a "water pill" (diuretic) that causes you to make more urine. This helps your body get rid of extra water and salt.

How to use Demadex

Take this medication by mouth as directed by your doctor, with or without food, usually once daily. It is best to avoid taking this medication within 4 hours of your bedtime to prevent having to get up to urinate.

Dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than directed.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day as directed. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Generally, it may take 4-6 weeks, and sometimes up to 12 weeks, before the full blood pressure-lowering effect is seen. Do not stop taking this medication without consulting your doctor.

Cholestyramine and colestipol can decrease the absorption of torsemide. If you are taking either of these drugs, separate the timing of each dose from torsemide by at least 2 hours.

Tell your doctor if your condition does not improve or if it worsens. If you are taking this medication to control high blood pressure, tell your doctor if your blood pressure readings remain high or increase.

Side Effects

Dizziness or headache may occur as your body adjusts to the medication. If either of these effects persist or worsen, tell your doctor or pharmacist promptly.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may cause a serious loss of body water (dehydration) and salt/minerals. Tell your doctor right away if you have any of these unlikely but serious side effects: muscle cramps, weakness, unusual tiredness, confusion, severe dizziness, fainting, drowsiness, unusual dry mouth/thirst, nausea, vomiting, fast/irregular heartbeat, unusual decrease in the amount of urine.

Tell your doctor right away if any of these rare but serious side effects occur: numbness/tingling/pain/redness/swelling of the arms/legs, hearing changes (such as ringing in the ears, temporary or permanent decreased hearing/deafness).

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
