This drug is used to treat high blood pressure. It is also used to lower the risk of strokes in patients with high blood pressure and an enlarged heart. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains two medications: losartan and hydrochlorothiazide. Losartan is an angiotensin receptor blocker (ARB) and works by relaxing blood vessels so that blood can flow more easily. Hydrochlorothiazide is a “water pill” (diuretic) that causes you to make more urine, which helps your body get rid of extra salt and water.
Hyzaar contains a combination of hydrochlorothiazide and losartan. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention. Losartan is an angiotensin II receptor antagonist. Losartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow. It is used to treat high blood pressure (hypertension). It is also used to lower the risk of stroke in certain people with heart disease.
Hyzaar may also be used for purposes not listed in this medication guide.
