Metoprolol vs. Carvedilol
See how Metoprolol and Carvedilol compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Metoprolol is beta-1 selective and taken once daily, while carvedilol also blocks alpha-1 receptors and is typically taken twice daily as the immediate-release tablet.
Both drugs treat hypertension and heart failure, but only carvedilol carries FDA approval for left ventricular dysfunction after a heart attack.
Metoprolol tends to cost less than carvedilol's extended-release capsule, though generic immediate-release versions of both drugs are inexpensive.
Metoprolol vs. Carvedilol Drug Summary
Metoprolol
Metoprolol succinate is a beta-1 selective beta-blocker taken as a once-daily extended-release tablet. It is FDA-approved to treat hypertension, angina, and stable heart failure by slowing heart rate and easing the heart's workload. Doctors also prescribe it off-label for atrial fibrillation rate control, migraine prevention, and essential tremor.
Carvedilol
Carvedilol is a combined alpha- and beta-blocker most often taken as an immediate-release tablet twice daily with food, though an extended-release capsule allows once-daily dosing. It is FDA-approved for chronic heart failure, left ventricular dysfunction after a heart attack, and hypertension. The added alpha-1 blockade relaxes blood vessels on top of its heart-rate-slowing effect.

Metoprolol vs. Carvedilol Indications
Metoprolol
Metoprolol succinate extended-release is FDA-approved for high blood pressure, chronic angina, and stable heart failure classified as NYHA Class II-IV. It works by blocking beta-1 receptors in the heart to slow heart rate and reduce the heart's oxygen demand. Off-label, clinicians also use it for atrial fibrillation rate control, migraine prevention, and essential tremor.
Hypertension, to lower blood pressure
Angina pectoris (chest pain)
Stable heart failure, NYHA Class II-IV
Off-label: atrial fibrillation rate control
Carvedilol
Carvedilol is FDA-approved for mild to severe chronic heart failure, left ventricular dysfunction following a heart attack, and hypertension. Its combined alpha-1 and beta blockade lowers blood pressure by relaxing blood vessels in addition to slowing the heart rate. It is not approved for acute decompensated heart failure or cardiogenic shock.
Mild to severe chronic heart failure
Left ventricular dysfunction after a heart attack
Hypertension, to lower blood pressure
Off-label: atrial fibrillation rate control
Metoprolol vs. Carvedilol Pros and Cons
Metoprolol
Metoprolol's beta-1 selectivity makes it a common choice for patients who also have asthma or COPD, since it carries a lower bronchospasm risk than non-selective beta-blockers like carvedilol. It has decades of use, once-daily dosing, and ranks among the least expensive beta-blockers.
Pros
Beta-1 selective, so lower bronchospasm risk in asthma or COPD
Once-daily extended-release dosing
Costs roughly $9 to $60 a month without insurance
No food restriction needed at dosing time
Cons
Not FDA-approved for left ventricular dysfunction after a heart attack
Lacks the alpha-1 blocking, vessel-relaxing effect carvedilol provides
Must be tapered gradually to avoid rebound chest pain or arrhythmia
Carvedilol
Carvedilol's combined alpha- and beta-blockade gives it a broader mechanism, with strong mortality-reduction data in chronic heart failure trials. Immediate-release dosing requires twice-daily administration with food, and the extended-release capsule can be considerably more expensive than generic metoprolol.
Pros
FDA-approved for left ventricular dysfunction after a heart attack
Added alpha-1 blockade directly relaxes blood vessels
Strong mortality-reduction evidence in chronic heart failure trials
Extended-release capsule option allows once-daily dosing
Cons
Immediate-release tablets must be taken twice daily with food
Extended-release capsules cost roughly $170 to $180 a month without insurance
More dose-dependent dizziness risk, up to 32% in trials
