What is triamterene (generic Dyrenium)?
Triamterene is a prescription diuretic medication used to treat edema (fluid retention) in patients with congestive heart failure, liver cirrhosis, and kidney disease. It is also occasionally used in combination with other medications to treat high blood pressure (hypertension).
Triamterene works by blocking the absorption of sodium in the kidneys, which helps reduce fluid levels in the body. It may also help lower cholesterol levels, as well as reduce the risk of heart failure and kidney damage.
Triamterene is available under the brand name Dyrenium and comes in the form of a capsule to take by mouth.
