Zaroxolyn (Metolazone)

Zaroxolyn (Metolazone) is a prescription diuretic medication used to help reduce fluid retention (edema) caused by conditions such as congestive heart failure, kidney disease, or liver cirrhosis. It works by helping the kidneys eliminate excess salt and water from the body, which helps lower swelling and improve breathing and comfort. Zaroxolyn is also sometimes used alongside other medications to help control high blood pressure.
