What is hydrochlorothiazide and amiloride?

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


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


The combination of hydrochlorothiazide and amiloride is used to treat fluid retention (edema) and high blood pressure (hypertension).
