What is Aldactazide?

Hydrochlorothiazide is a thiazide diuretic (water pill). Spironolactone is a potassium-sparing diuretic.

Aldactazide is a combination medicine used to treat fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney disorder called nephrotic syndrome. Aldactazide also treats high blood pressure (hypertension), or low potassium levels (hypokalemia) caused by using a diuretic.

Do not use this medicine for any condition that has not been checked by your doctor.

Aldactazide may also be used for purposes not listed in this medication guide.
