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. Moduretic may be used alone or with other medicines.
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.
Drinking alcohol can increase certain side effects of hydrochlorothiazide and amiloride. Do not use salt substitutes or low-sodium milk products that contain potassium. These products could cause your potassium levels to get too high while you are taking hydrochlorothiazide and amiloride. Moduretic may cause dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Moduretic with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it. Moduretic may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to Moduretic. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
Do not use Moduretic if you are allergic to any ingredient in Moduretic or any other sulfonamide (eg, sulfamethoxazole); you are unable to urinate, have severely decreased kidney function, or high blood potassium; you are taking other potassium-sparing diuretics (eg, spironolactone), potassium supplements, salt substitutes containing potassium, or dofetilide.
