metolazone

Metolazone is a "water pill" (diuretic) that increases the amount of urine you make, which causes your body to get rid of excess water. This drug is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication also reduces swelling/fluid retention (edema) which can result from conditions such as congestive heart failure or kidney disease. This can help to improve symptoms such as trouble breathing.

About metolazone

Metolazone is a "water pill" (diuretic) that increases the amount of urine you make, which causes your body to get rid of excess water. This drug is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

This medication also reduces swelling/fluid retention (edema) which can result from conditions such as congestive heart failure or kidney disease. This can help to improve symptoms such as trouble breathing.

Take this medication by mouth with or without food, usually once daily, or as directed by your doctor. The dosage is based on your medical condition and response to therapy.

If you take this drug too close to bedtime, you may need to wake up to urinate. Therefore, it is best to take this medication at least 4 hours before your bedtime.

Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day as directed. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Do not stop taking this medication without consulting your doctor. It may take up to 3-6 weeks to see a lowering of your blood pressure.

Cholestyramine and colestipol can decrease the absorption of metolazone. If you are taking either of these drugs, separate metolazone from cholestyramine by at least 4 hours and from colestipol by at least 2 hours.

If your condition persists or worsens, contact your doctor or pharmacist.

Dizziness, lightheadedness, headache, blurred vision, loss of appetite, stomach upset, diarrhea, or constipation may occur as your body adjusts to the medication. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
