Amiloride-HCTZ is a diuretic -- commonly known as a "water pill" -- often prescribed for people who have high blood pressure (hypertension) or water retention (edema) associated with congestive heart failure. Brand-name amiloride-HCTZ, sold under the name Moduretic®, was originally made by Merck, but this drug is no longer being made. Generic amiloride-HCTZ is still available, however, and this medicine is made by a few different manufacturers.
This medication works by increasing the amount of salt and water removed from the blood, which causes a decrease in blood volume. Amiloride-HCTZ comes in tablet form and is usually taken once a day. Although most people have no problems with this medicine, common side effects can include rash, dizziness, and headache.
