Discovering the 10 Most Common Side Effects of Metoprolol: A Helpful Guide for Anyone Taking It
Metoprolol is a beta-blocker commonly prescribed for conditions such as high blood pressure, chest pain (angina), certain heart rhythm problems, and some types of heart failure. Like all medicines, it can cause side effects. Many people tolerate it well, and some side effects may improve as the body adjusts. (NCBI)
Here are 10 commonly reported side effects of metoprolol: (DailyMed)
- Tiredness or fatigue
Feeling unusually tired, low on energy, or less able to exercise is one of the most frequently reported effects. - Dizziness or lightheadedness
Metoprolol can lower heart rate and blood pressure, which may cause dizziness, especially when standing up quickly. - Slow heartbeat (bradycardia)
Because metoprolol slows the heart’s workload, some people may notice a slower pulse. - Low blood pressure (hypotension)
Symptoms may include weakness, dizziness, or feeling faint. - Shortness of breath
Some people may experience breathing discomfort, particularly those with certain lung conditions or heart problems. - Diarrhea or stomach discomfort
Digestive effects such as diarrhea, nausea, or stomach upset can occur. - Mood changes, including depression
Depression and other mood-related symptoms have been reported in some people taking metoprolol. - Cold hands and feet
Reduced circulation to the extremities can make fingers and toes feel colder than usual. - Skin reactions (itching or rash)
Allergic-type skin symptoms such as itching or rash can occur. - Sleep-related changes
Some people report insomnia, unusual dreams, or nightmares while taking beta-blockers. (NCBI)
When to contact a healthcare professional
Seek medical advice promptly if you experience:
- Fainting or severe dizziness
- New or worsening chest pain
- Trouble breathing or wheezing
- Very slow heartbeat
- Signs of an allergic reaction (such as swelling or difficulty breathing)
Do not stop metoprolol suddenly without medical guidance, because abruptly stopping beta-blockers can cause serious heart-related problems in some people. (FDA Access Data)
If you are taking metoprolol and notice side effects, it can help to record when symptoms occur, your dose, your blood pressure, and your heart rate and share that information with your healthcare provider.
