Patient Education

Triamterene


Triamterene is used alone or with other medications to treat edema (fluid retention; excess fluid held in body tissues) caused by various conditions, including liver and heart disease. Triamterene is in a class of medications called diuretics ('water pills'). It causes the kidneys to eliminate unneeded water and sodium from the body into the urine, but reduces the loss of potassium.
