Information on Tablets A-Z
Generic ingredients: Amiloride, Hydrochlorothiazide
Why is this drug 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 this drug: 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.
