Metoprolol Side Effects: 10 Things People May Not Always Expect
Metoprolol is a medication in the beta-blocker family. It is commonly prescribed for conditions such as:
- High blood pressure
- Chest pain (angina)
- Certain heart rhythm problems
- Heart failure
- After some heart attacks
It works by slowing the heart rate and reducing the heart’s workload. Like all medicines, it can cause side effects, although many people take it without major problems.
1. Tiredness or low energy
One of the most commonly reported effects:
- Feeling more fatigued than usual
- Reduced exercise tolerance
- Sleepiness, especially when starting treatment
This may improve as the body adjusts.
2. Slow heartbeat (bradycardia)
Because metoprolol lowers heart rate, some people may notice:
- A slower pulse
- Lightheadedness
- Weakness
A very slow heart rate should be discussed with a healthcare professional.
3. Dizziness or feeling faint
Blood pressure changes can cause:
- Dizziness when standing up
- Feeling unsteady
- Increased fall risk, especially in older adults
