Key takeaways
Carvedilol (Coreg) and aenolol (Tenormin) are both beta blockers used to treat high blood pressure and heart-related issues, but they have some key differences. Carvedilol is a non-selective beta blocker that also blocks alpha receptors, which helps relax blood vessels and slow heart rate. It is used for high blood pressure, heart failure, and reducing the risk of death after a heart attack. Carvedilol comes in immediate-release tablets taken twice daily and extended-release capsules taken once daily. Common side effects include dizziness, tiredness, and diarrhea. Atenolol, on the other hand, is a cardioselective beta blocker, meaning it primarily affects the heart. It is used for high blood pressure, chest pain (angina), and lowering the risk of death after a heart attack. Atenolol is typically taken once daily. Common side effects include dizziness, tiredness, and cold hands and feet. Unlike carvedilol, atenolol is not recommended during pregnancy or breastfeeding. Both medications can hide symptoms of low blood sugar and should not be stopped suddenly to avoid serious heart issues.
