Metoprolol is a beta-blocker commonly used for high blood pressure, chest pain (angina), heart rhythm problems, and sometimes 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
Very common. It slows the heart rate, which can make you feel low on energy.
2. 🧠 Dizziness or Lightheadedness
Especially when standing up quickly (due to lowered blood pressure).
3. ❤️ Slow Heart Rate (Bradycardia)
Your heart may beat slower than normal, sometimes causing weakness or faintness.
4. 😵 Low Blood Pressure
Can lead to:
- Feeling faint
- Blurred vision
- Weakness
5. ❄️ Cold Hands and Feet
Reduced blood flow to extremities can make them feel cold or numb.
6. 😔 Depression or Mood Changes
Some people may notice low mood, irritability, or emotional dullness.
7. 🫁 Shortness of Breath
More likely in people with asthma or other breathing conditions (metoprolol can tighten airways in some cases).
8. ⚖️ Weight Gain
Mild weight gain can happen in some people due to fluid retention or reduced activity.
9. 😴 Sleep Problems / Vivid Dreams
Can include:
- Insomnia
- Nightmares
- Restless sleep
10. 🩸 Sexual Side Effects
Some people report:
- Lower libido
- Erectile dysfunction
🚨 When to seek medical help
Contact a doctor urgently if you experience:
- Very slow heartbeat
- Severe dizziness or fainting
- Difficulty breathing
- Swelling in legs or sudden weight gain
- Chest pain worsening
⚠️ Important note
Do not stop Metoprolol suddenly without medical advice—this can cause rebound high blood pressure or heart problems.
