Zaroxolyn Uses, Dosage, Side Effects & Warnings

Introduction

Zaroxolyn (metolazone) is an oral diuretic medication used to treat high blood pressure, fluid retention (edema), and to help prevent strokes, heart attacks, and kidney problems. It works by increasing the amount of salt and water eliminated from the body as urine, which helps to lower blood pressure and reduce swelling caused by excess fluid.

Uses of Zaroxolyn

Zaroxolyn is primarily used to treat hypertension (high blood pressure) and edema (fluid retention) associated with congestive heart failure, kidney disease, and other conditions.

The usual starting dose for adults is 2.5 to 5 mg once daily, which may be increased gradually up to a maximum of 20 mg per day.
