Discovering the 10 Most Common Side Effects of Metoprolol
Metoprolol is a beta-blocker prescribed for conditions such as high blood pressure, angina, certain heart-rhythm problems, and heart failure. It works partly by slowing the heart rate and reducing the heart’s workload.
Here are 10 possible side effects to know about:
-
Tiredness or fatigue — particularly when beginning treatment or changing the dose.
-
Dizziness or lightheadedness — often related to lowered blood pressure.
-
Slow heartbeat — some slowing is expected, but an excessively slow pulse can cause symptoms.
-
Low blood pressure — may cause weakness, dizziness, or fainting.
-
Cold hands and feet — reduced peripheral circulation can make your extremities feel colder.
-
Shortness of breath or wheezing — particularly important for people with asthma or other breathing conditions.
-
Nausea or diarrhea — gastrointestinal symptoms can occur.
-
Sleep disturbances or vivid dreams — some people notice changes in sleep.
-
Mood changes or reduced energy — depression has been reported, although it isn’t necessarily caused by the medication in every case.
-
Sexual difficulties — decreased libido or erectile problems can occur.
🚨 When to seek medical help
Contact a healthcare professional promptly if you develop fainting, severe dizziness, significant breathing difficulty, chest pain, swelling with unexplained weight gain, or a very slow/irregular heartbeat.
Most importantly, don’t stop metoprolol suddenly. Abrupt withdrawal can cause a dangerous increase in heart rate and blood pressure and may worsen angina or other heart problems.
If you’re having a particular side effect, your dose, formulation (metoprolol tartrate versus metoprolol succinate), age, and reason for taking it can all affect how significant the symptom is.
