How Does Triamterene-HCTZ Work?
Triamterene-HCTZ is a diuretic. These drugs are commonly referred to as “water pills.” Triamterene-HCTZ contains two diuretics that work together to keep electrolyte levels in balance. Hydrochlorothiazide, while effective, often causes low potassium levels in the blood. On the other hand, triamterene is a “potassium-sparing” diuretic, meaning that it can actually increase potassium levels in the blood. When taken together, these medications balance each other out.
