Compare Coreg vs. Zebeta

Carvedilol (Coreg) and bisoprolol (formerly branded as Zebeta) are both beta blockers used to treat high blood pressure, but they have some key differences. Carvedilol is also used to manage heart failure and reduce the risk of death after a heart attack, while bisoprolol is typically only used for high blood pressure when other medications aren't effective. Carvedilol comes in both immediate-release tablets taken twice daily and extended-release capsules taken once daily, whereas bisoprolol is taken once daily. Carvedilol is a non-selective beta blocker, affecting both the heart and blood vessels, while bisoprolol is cardioselective, primarily targeting the heart, which may make it less likely to cause breathing problems. Common side effects of carvedilol include dizziness and tiredness, while bisoprolol commonly causes headaches and fatigue. Both medications are available as lower-cost generics.
