Metoprolol is a beta-blocker used for conditions such as high blood pressure, angina, heart failure, certain abnormal heart rhythms, and after some heart attacks. Because it slows the heart and lowers blood pressure, some side effects are related to those effects. MedlinePlus+1

When to seek medical attention
Contact a healthcare professional promptly if you develop fainting, significant swelling of the legs or feet, unexplained weight gain, worsening shortness of breath, or a rapid/irregular heartbeat. These can sometimes indicate a more serious cardiovascular problem. MedlinePlus
If you have diabetes, metoprolol can also make some warning symptoms of low blood sugar—particularly a rapid heartbeat—less noticeable. MedlinePlus
Don’t stop it suddenly
Even if you’re experiencing side effects, don’t abruptly discontinue metoprolol without medical advice. Sudden withdrawal can cause serious heart problems, and the prescribing information recommends gradual reduction when discontinuation is appropriate. MedlinePlus+1
Metoprolol comes in different forms, particularly metoprolol tartrate and metoprolol succinate extended-release, so the exact dosing and instructions can differ.
