Metoprolol is a medication commonly used for conditions such as high blood pressure, chest pain (angina), heart rhythm problems, and heart failure. It belongs to a group of medicines called beta blockers, which work by slowing the heart rate and reducing the workload on the heart.
Here are 10 common side effects of metoprolol that people taking it may notice:
- Tiredness or fatigue
Feeling unusually tired, especially when starting the medication, is one of the most frequently reported effects. - Dizziness or lightheadedness
This may happen because metoprolol can lower blood pressure and slow heart rate. - Slow heartbeat (bradycardia)
A slower pulse is an intended effect for many patients, but an unusually slow heartbeat may need medical attention. - Low blood pressure (hypotension)
Some people may feel faint, weak, or dizzy, especially when standing up quickly. - Cold hands and feet
Reduced circulation to the extremities can cause a sensation of coldness. - Sleep changes or vivid dreams
Some people report trouble sleeping, unusual dreams, or changes in sleep patterns. - Nausea or stomach discomfort
Digestive symptoms such as nausea, diarrhea, or stomach upset can occur. - Shortness of breath or reduced exercise tolerance
Some people notice they tire more easily during physical activity. - Mood changes
Less commonly, people may experience low mood or changes in emotional well-being. - Sexual side effects
Some people report reduced sexual interest or difficulty with sexual function.
Important: Do not stop taking metoprolol suddenly unless a healthcare professional tells you to. Abruptly stopping a beta blocker can worsen some heart conditions and may cause serious problems.
Seek medical advice promptly if you experience symptoms such as fainting, severe dizziness, chest pain, new or worsening shortness of breath, swelling, or a very slow or irregular heartbeat.
If you are taking metoprolol and have concerns about a specific side effect, the dose, or how it interacts with other medicines, a pharmacist or healthcare professional can help review your situation.
