10 is a beta-blocker used to treat conditions Important Side Effects of Metoprolol You Need to Know
Metoprolol is a beta-blocker used to treat conditions such as high blood pressure, angina, certain heart-rhythm disorders, and heart failure. It works partly by slowing the heart rate and reducing the heart’s workload.
Most people tolerate it well, but side effects can occur.
1. Fatigue or Tiredness
Feeling unusually tired or having less energy is relatively common, especially when starting metoprolol or after a dose increase.
2. Dizziness or Lightheadedness
Lower blood pressure and a slower heart rate can cause dizziness, particularly when standing up quickly.
3. Slow Heart Rate
Metoprolol intentionally slows the heart, but in some people the rate can become too slow.
Fainting, severe dizziness, unusual weakness, or breathing difficulty together with a slow heartbeat warrants prompt medical attention.
4. Cold Hands and Feet
Some people notice colder hands or feet while taking beta-blockers.
5. Sleep Problems or Vivid Dreams
Difficulty sleeping, unusual dreams, or changes in sleep patterns have been reported with beta-blockers.
6. Nausea and Other Digestive Problems
Nausea, diarrhea, constipation, or abdominal discomfort can occur.
Persistent or severe symptoms should be discussed with a healthcare professional.
7. Low Blood Pressure
If blood pressure falls too low, you may experience dizziness, weakness, blurred vision, or fainting.
8. Shortness of Breath
Breathing problems can occur in some people, particularly those with asthma or other airway diseases. New or worsening breathing difficulty should be evaluated rather than assumed to be a routine side effect.
9. Mood Changes
Depression or other mood changes have been reported, although these symptoms can have many causes.
Tell your healthcare professional about persistent or significant changes in mood.
10. Sexual Problems
Some people experience reduced sexual desire or erectile difficulties while taking beta-blockers. Cardiovascular disease and other medications can also contribute, so the medication isn’t necessarily the only explanation.
Don’t Stop Metoprolol Suddenly
This is especially important: don’t abruptly stop regularly prescribed metoprolol without medical guidance.
Sudden withdrawal can cause a rapid increase in heart rate and blood pressure and may worsen angina or increase cardiovascular risk in some people. If the medicine is causing problems, a clinician can determine whether the dose should be adjusted or whether an alternative is appropriate.
When to Seek Urgent Care
Get urgent medical attention for severe chest pain, fainting, serious difficulty breathing, or a very slow heartbeat accompanied by significant symptoms.
Bottom Line
Fatigue, dizziness, slow heart rate, cold extremities, sleep changes, and digestive symptoms are among the possible effects of metoprolol. They don’t occur in everyone, and the medication can provide important benefits when appropriately prescribed.
If you’re experiencing troublesome symptoms, talk with your doctor or pharmacist before changing or stopping the medication.
