Frequently Asked Questions

What is the main difference between Bystolic and Metoprolol?

+

Bystolic (Nebivolol) is a beta-blocker that also helps dilate blood vessels, improving blood flow. Metoprolol primarily reduces heart rate and blood pressure but does not have the same vasodilation effect.

Which medication is better for high blood pressure?

+

Both medications are effective for high blood pressure. Bystolic may be preferred for patients needing additional blood vessel relaxation, while Metoprolol is often chosen for patients with heart disease or previous heart attacks.

Can Bystolic or Metoprolol be used for heart failure?

+

Yes, but Metoprolol succinate (Toprol XL) is FDA-approved for heart failure, while Bystolic is sometimes used off-label but lacks as much clinical evidence for this condition.

Does Bystolic have fewer side effects than Metoprolol?

+

Bystolic may cause fewer side effects like fatigue and dizziness compared to Metoprolol, but both can cause low heart rate, dizziness, and tiredness.
