Why is Moduretic prescribed?
Moduretic is a diuretic combination used in the treatment of high blood pressure and congestive heart failure, conditions which require the elimination of excess fluid (water) from the body. When used for high blood pressure, Moduretic can be used alone or with other high blood pressure medications. Diuretics help your body produce and eliminate more urine, which helps lower blood pressure. Amiloride, one of the ingredients, helps minimize the potassium loss that can be caused by the other component, hydrochlorothiazide.
Most important fact about Moduretic
If you have high blood pressure, you must take Moduretic regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Moduretic; and you must continue taking it even if you are feeling well. Moduretic does not cure high blood pressure; it merely keeps it under control.
How should you take Moduretic?
Take Moduretic with food.
Take Moduretic exactly as prescribed by your doctor. Stopping Moduretic suddenly could cause your condition to worsen.
--If you miss a dose...
Take the forgotten dose as soon as you remember. If it is almost time for your next does, skip the one you missed and go back to your regular schedule. Never take a double dose.
--Storage instructions...
Store at room temperature. Keep Moduretic in the container it came in, tightly closed, and protected from moisture, light, and freezing.

Why should Moduretic not be prescribed?
If you are unable to urinate or have serious kidney disease, or if you have high potassium levels in your blood, you should not take Moduretic.
If you are sensitive to or have ever had an allergic reaction to amiloride, hydrochlorothiazide or similar drugs, or if you are sensitive to other sulfonamide-derived drugs, you should not take Moduretic. Make sure your doctor is aware of any drug reactions you may have experienced.
Special warnings about Moduretic

You should also limit your consumption of potassium-rich foods such as bananas, prunes, raisins, orange juice, and whole and skim milk. Ask your doctor for advice on how much of these foods to consume.
If you are taking Moduretic, a complete assessment of your kidney function should be done; kidney function should continue to be monitored.
