Discovering the 10 Most Common Side Effects of Metoprolol: A Helpful Guide for Anyone Taking This Medication
Metoprolol is a beta blocker commonly prescribed to treat high blood pressure, chest pain (angina), heart failure, and certain heart rhythm disorders. Many people take it safely for years, but like all medications, it can cause side effects. Most are mild and improve as your body adjusts, while others may need medical attention.
Here are 10 of the most common side effects:
- Fatigue or tiredness
- One of the most frequently reported side effects.
- You may feel less energetic, especially during the first few weeks.
- Dizziness or lightheadedness
- Often occurs when standing up quickly because the medication lowers blood pressure.
- Standing up slowly can help reduce this effect.
- Slow heart rate (bradycardia)
- Metoprolol intentionally slows the heart, but in some people it may become too slow.
- Contact your healthcare provider if you experience fainting, severe dizziness, or an unusually slow pulse.
- Low blood pressure (hypotension)
- Symptoms include weakness, blurred vision, dizziness, or feeling faint.
- Cold hands and feet
- Reduced blood flow to the extremities may make your fingers and toes feel cold.
- Shortness of breath
- Although uncommon, some people—particularly those with asthma or chronic lung disease—may notice breathing difficulties.
- Sleep disturbances
- Some people report insomnia, vivid dreams, or unusual dreams while taking metoprolol.
- Digestive problems
- Nausea, diarrhea, constipation, stomach discomfort, or abdominal pain may occur.
- Depression or mood changes
- A small number of people experience low mood, decreased motivation, or changes in emotional well-being.
- Sexual side effects
- Some people may notice reduced libido or difficulty achieving or maintaining an erection
