triamterene is a combination medication. Hydrochlorothiazide is a thiazide diuretic (water pill) that makes you urinate more.

Triamterene is a potassium-sparing diuretic (water pill). It also works in your kidneys to remove extra water and electrolytes, but it doesn’t remove potassium from your body.
