Metoprolol is a commonly prescribed beta blocker used to treat conditions such as high blood pressure, certain heart rhythm problems, angina, and heart failure.
While many people tolerate Metoprolol well, some side effects may receive less attention during routine discussions.
10 side effects that can be overlooked
- Fatigue or low energy
- One of the most common complaints.
- May be more noticeable when starting the medication or after a dose increase.
- Dizziness
- Can occur because metoprolol lowers heart rate and blood pressure.
- Cold hands and feet
- Reduced circulation to the extremities can make them feel cooler.
- Exercise intolerance
- Some people find it harder to reach previous exercise intensity because the medication limits how quickly the heart rate rises.
- Sleep disturbances
- Vivid dreams, insomnia, or unusual sleep patterns can occur in some individuals.
- Depressed mood
- Mood changes have been reported, although the relationship is not always clear and can vary from person to person.
- Slower heart rate
- A lower pulse is expected to some extent, but an excessively slow heart rate may require medical evaluation.
- Sexual side effects
- Some people report reduced libido or erectile difficulties.
- Digestive symptoms
- Nausea, stomach discomfort, diarrhea, or constipation can occur.
- Masking low blood sugar symptoms
- In people with diabetes, beta blockers can make some warning signs of low blood sugar less noticeable.
When to contact a healthcare professional
Seek medical advice if you experience:
- Fainting
- Severe dizziness
- Shortness of breath
- Wheezing
- Chest pain
- A very slow heart rate
- Significant swelling
- New or worsening symptoms
Important note
Do not stop metoprolol suddenly unless instructed by a healthcare professional. Abrupt discontinuation can sometimes cause serious cardiovascular problems, including worsening chest pain or heart rhythm issues.
If you’re taking metoprolol and are concerned about side effects, your doctor or pharmacist can help determine whether the medication, dosage, or another factor is responsible and discuss possible alternatives.
