What is Midamor (amiloride)?

Amiloride is a potassium-sparing diuretic (water pill) that prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.

Amiloride is used to treat or prevent hypokalemia (low potassium levels in the blood).

Amiloride may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about Midamor (amiloride)?

Do not use this medication if you have kidney disease, urination problems, or high levels of potassium in your blood. Do not use potassium supplements or other diuretics while you are taking amiloride.

Before using this medication, tell your doctor if you have heart or liver disease, or a breathing disorder.

Avoid drinking alcohol, which can increase some of the side effects of amiloride.

Avoid a diet high in salt. Too much salt will cause your body to retain water and can make this medication less effective.

Do not use salt substitutes or low-sodium milk products that contain potassium. These products could cause your potassium levels to get too high while you are taking amiloride.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
