Metoprolol is a beta-blocker commonly used for high blood pressure, chest pain (angina), heart rhythm problems, and after heart attacks. Like all medicines, it can cause side effects—some mild, some more serious.
Here are 10 Metoprolol side effects you should know:
1) Fatigue / Tiredness
One of the most common effects. Your heart rate slows down, which can make you feel unusually low on energy.
2) Dizziness or Lightheadedness
Especially when standing up quickly. This happens due to lowered blood pressure.
3) Slow Heart Rate (Bradycardia)
Metoprolol reduces heart rate, but sometimes it can slow it too much, causing weakness or fainting.
4) Low Blood Pressure (Hypotension)
Can lead to blurred vision, dizziness, or feeling faint.
5) Cold Hands and Feet
Reduced circulation in extremities is common with beta blockers.
6) Shortness of Breath (in sensitive people)
More likely if you have asthma or other lung conditions, because it can slightly affect airway muscles.
7) Sleep Problems / Vivid Dreams
Some people report insomnia, nightmares, or unusual dreams.
8) Depression or Mood Changes
Not everyone experiences this, but mood lowering or emotional blunting can occur in some users.
9) Sexual Dysfunction
Reduced libido or erectile dysfunction can happen in some people.
10) Weight Gain
Usually mild, but some people notice increased weight over time due to metabolism changes or fluid retention.
🚨 Important warning signs (seek medical help)
- Severe shortness of breath
- Fainting or extreme dizziness
- Very slow heartbeat
- Swelling of legs or sudden weight gain
- Chest pain worsening
