Key takeaways
Hyzaar (losartan/hydrochlorothiazide) and carvedilol (Coreg) are both used to treat high blood pressure, but they belong to different medication classes and have different uses. Hyzaar is a combination of an angiotensin II receptor blocker (ARB) and a diuretic, taken once daily, and is also used to lower the risk of stroke in people with high blood pressure and an enlarged left ventricle. Carvedilol, a beta blocker, is taken either twice daily in its immediate-release form or once daily in its extended-release form, and is also used to manage heart failure and reduce the risk of death after a heart attack. While Hyzaar can cause increased urination and should be avoided during pregnancy, carvedilol can cause tiredness, dry eyes, and should not be taken if you have asthma or severe liver problems. Additionally, both medicatiosn are available as lower-cost generics.
