Description

Hyzaar (generic name: losartan potassium / hydrochlorothiazide; brand names include: Cosart-H) is a combination of an angiotensin II receptor antagonist (losartan potassium) and a diuretic (hydrochlorothiazide).

Hyzaar is used to:

lower high blood pressure (hypertension);
lower the chance of stroke in patients with high blood pressure and a heart problem called left ventricular hypertrophy (LVH).

The losartan ingredient in Hyzaar helps your blood vessels relax so your blood pressure is lower. The hydrochlorothiazide ingredient in Hyzaar works by making your kidneys pass more water and salt.

Hyzaar is not addictive.
