What is hydrochlorothiazide and spironolactone?

Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.

Spironolactone is a potassium-sparing diuretic that also prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.

Hydrochlorothiazide and spironolactone 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. This medication also treats high blood pressure (hypertension).
