Drug Uses

Moduretic is used for treating fluid retention (edema) and high blood pressure. It may be used alone or with other medicines. It may also be used for other conditions as determined by your doctor.

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.

Drug Class and Mechanism

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.

Missed Dose

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.

Storage

Store this medicine at room temperature in a tightly-closed container, away from heat and light.
