Key takeaways
Metoprolol succinate (Toprol XL) and carvedilol (Coreg) are both beta blockers used to treat heart conditions, but they have some key differences. Metoprolol succinate is a selective beta blocker, meaning it mainly affects your heart, and is typically taken once daily. It's used for high blood pressure, chest pain, and heart failure. Carvedilol, on the other hand, is both an alpha and beta blocker, which means it also relaxes your blood vessels. It can be taken as an immediate-release tablet twice daily or as an extended-release capsule once daily. Carvedilol is used for high blood pressure, heart failure, and to lower the risk of death after a heart attack. Both medications can cause dizziness and tiredness, but carvedilol may also cause weight gain and dry eyes. Additionally, carvedilol should not be taken if you have asthma or severe liver problems. Both medications are available in generic forms, making them more affordable options.
