10 Common Side Effects of Metoprolol: A Helpful Guide for People Taking This Medication
Metoprolol is a beta-blocker commonly prescribed for conditions such as high blood pressure, angina (chest pain), certain heart rhythm problems, and heart failure. It works by slowing the heart rate and reducing the workload on the heart.
Many people take metoprolol without major problems, but side effects can occur—especially when starting treatment or changing the dose.
