10 Metoprolol Side Effects That Are Often Discussed Less Often
Metoprolol is a beta-blocker commonly prescribed for high blood pressure, certain heart conditions, chest pain (angina), and heart failure. Most people tolerate it well, but side effects can occur.
Possible Side Effects
- Fatigue or low energy
- One of the most common side effects, especially when starting treatment or after a dose increase.
- Slow heart rate (bradycardia)
- Metoprolol lowers heart rate, which can become too slow in some people.
- Dizziness or lightheadedness
- This may occur when standing up quickly because blood pressure is lower.
- Cold hands and feet
- Reduced blood flow to the extremities can make them feel cold.
- Exercise intolerance
- You may notice it’s harder to reach your usual exercise intensity because the medication limits how fast your heart can beat.
- Sleep disturbances
- Some people report vivid dreams or difficulty sleeping, although this is not universal.
- Digestive symptoms
- Nausea, diarrhea, constipation, or stomach discomfort can occur.
- Mood changes
- Some people experience low mood or depression, but the relationship is not clear-cut and does not affect everyone.
- Sexual side effects
- Decreased libido or erectile dysfunction can occur in some individuals.
- Masking low blood sugar symptoms
- In people with diabetes, metoprolol can make it harder to notice warning signs of low blood sugar, such as a rapid heartbeat
