Hyzaar is a combination medication containing Losartan (50mg) and Hydrochlorothiazide (12.5mg) used to treat high blood pressure (hypertension). Each pack contains 30 tablets. The medication works by relaxing blood vessels and helping the body eliminate excess fluid to lower blood pressure. Hyzaar combines two medications that work in different ways to lower blood pressure: Losartan (an angiotensin II receptor blocker) and Hydrochlorothiazide (a diuretic or 'water pill'). The tablets come in a blister pack format with clear markings for tracking doses. This is a prescription-only medication that should be taken exactly as prescribed by your healthcare provider, typically once daily. The medication should be stored at room temperature away from moisture and heat.
