Metoprolol and Hydrochlorothiazide Overview

Metoprolol and hydrochlorothiazide is a prescription medication used to treat high blood pressure.

Metoprolol and hydrochlorothiazide is a single product containing 2 medications: metoprolol and hydrochlorothiazide. Metoprolol belongs to a group of drugs called beta blockers, which work by relaxing blood vessels and slowing heart rate. This improves blood flow and decreases overall blood pressure. Hydrochlorothiazide belongs to a group of drugs called thiazide diuretics, which work by stopping reabsorption of salt into your body. This prevents fluid from building up in the body.

This medication comes in tablet form and can be given once or twice daily with or immediately following meals.
