Key takeaways
Amlodipine (Norvasc) and Carvedilol (Coreg) are both used to treat high blood pressure, but they belong to different medication classes and have distinct uses and side effects. Amlodipine is a calcium channel blocker that helps relax blood vessels and is also used for coronary artery disease. It is typically taken once daily and is available in both tablet and liquid forms. Common side effects include swelling and tiredness. Carvedilol, on the other hand, is a beta blocker that not only lowers blood pressure but also manages heart failure and reduces the risk of death after a heart attack. It comes in immediate-release tablets taken twice daily and extended-release capsules taken once daily. Carvedilol can cause dizziness, tiredness, and diarrhea, and it must be taken with food. Unlike amlodipine, carvedilol should not be used by people with asthma or certain severe heart conditions. Both medications are available as lower-cost generics.
