Metoprolol is a beta blocker that slows the heart rate and lowers blood pressure. Many people take it safely, but your body may show signs that the medication is affecting you. Here are 10 common body signals to pay attention to:
- Unusual tiredness or low energy
- Metoprolol can slow your heart rate and reduce how strongly your heart responds during activity, which may make some people feel fatigued.
- Dizziness or lightheadedness
- This can happen if blood pressure drops too low, especially when standing up quickly.
- A slower-than-usual heartbeat
- A lower resting heart rate is an expected effect, but a very slow pulse with weakness, fainting, or confusion should be checked.
- Cold hands and feet
- Some people notice cooler extremities because beta blockers can affect circulation to the skin.
- Shortness of breath or reduced exercise tolerance
- You may notice it takes longer to recover after activity because your heart rate cannot rise as quickly.
- Sleep changes or vivid dreams
- Some people report unusual dreams, trouble sleeping, or changes in sleep patterns.
- Mood changes
- Rarely, people report low mood or changes in emotional well-being.
- Digestive changes
- Nausea, diarrhea, constipation, or stomach discomfort can occur.
- Sexual side effects
- Some people experience reduced libido or erectile difficulties.
- Signs of low blood sugar being harder to notice (in people with diabetes)
- Metoprolol can reduce warning signs such as a racing heartbeat during hypoglycemia.
Contact a healthcare professional if you notice:
- Fainting or severe dizziness
- New or worsening chest pain
- Trouble breathing or wheezing
- A very slow or irregular heartbeat
- Sudden swelling of the legs or rapid weight gain
