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) in people with high blood pressure or congestive heart failure.
Amiloride is usually given together with other medicines.
Amiloride may also be used for purposes not listed in this medication guide.

Take amiloride with food.
Your doctor may recommend you eat certain foods or take supplements to keep your potassium from getting too low. Follow the diet and medication plan created for you by your doctor or nutrition counselor.
While using amiloride, you will need frequent blood tests. Your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG).
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using amiloride. You may need to stop taking amiloride at least 3 days before having a glucose tolerance test.

What happens if I miss a dose?

What should I avoid while taking Midamor (amiloride)?
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 a diet high in salt. Too much salt will cause your body to retain water and can make this medication less effective.
Drinking alcohol with this medicine can cause side effects.
Avoid becoming overheated or dehydrated during exercise, in hot weather, or by not drinking enough fluids. 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.
