Active Ingredient: amiloride, hydrochlorothiazide
Moduretic is used for treating fluid retention (edema) and high blood pressure. It may be used alone or with other medicines. Moduretic is a diuretic (water pill) and is a combination of a potassium-sparing diuretic (amiloride) and a thiazide diuretic (hydrochlorothiazide). It works by making the kidneys eliminate sodium (salt) and water from the body, which helps to lower blood pressure. The amiloride component helps minimize potassium loss.
Use Moduretic as directed by your doctor.
- Take Moduretic by mouth with food.
- Moduretic may increase the amount of urine or cause you to urinate more often when you first start taking it. To keep this from disturbing your sleep, try to take your dose before 6 pm.
- If you miss a dose of Moduretic, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
