10 Common Side Effects of Metoprolol: A Helpful Guide
Metoprolol is a beta-blocker used for conditions including high blood pressure, angina, and some heart-rhythm or heart-related conditions. Many people take it without major problems, but side effects can occur.
Commonly reported effects
-
Tiredness or fatigue — slowing the heart rate can make some people feel less energetic.
-
Dizziness or lightheadedness — particularly when getting up quickly.
-
Slow heartbeat — metoprolol is intended to reduce heart rate, but an excessively low rate can be concerning.
-
Cold hands or feet — some people notice increased sensitivity to cold.
-
Low blood pressure — this may cause weakness, dizziness, or faintness.
-
Shortness of breath — this should be taken seriously, particularly in someone with a history of breathing problems.
-
Sleep problems or vivid dreams — changes in sleep have been reported.
-
Depressed mood — mood changes can occur in some people.
-
Nausea or stomach discomfort — digestive symptoms are possible.
-
Sexual difficulties — reduced sexual function or libido can occur in some people.
Don’t stop it suddenly
If you’ve been taking metoprolol regularly, don’t stop it abruptly unless a healthcare professional tells you to. Suddenly stopping a beta-blocker can cause a rapid increase in heart rate or blood pressure and may worsen certain heart conditions.
Seek urgent medical attention for fainting, severe breathing difficulty, chest pain, or a very slow/irregular heartbeat.
If side effects are bothersome, a clinician can determine whether they are likely related to metoprolol and whether the dose or treatment needs adjustment.
