When to seek medical attention
Contact a healthcare professional promptly for new or worsening shortness of breath, swollen legs, an irregular heartbeat, unexplained bruising, or significant dizziness/fainting. Chest pain that is new, severe, or doesn’t settle requires urgent evaluation. nhs.uk
A particularly important point: don’t suddenly stop metoprolol without medical advice. Abrupt withdrawal can worsen the underlying heart condition and, in some circumstances, cause serious cardiovascular problems. Medicines.org.uk+1
If you’re taking metoprolol and experiencing cold feet, heavy legs, nighttime cramps, or a slow pulse, tell me your dose and whether you’re taking metoprolol tartrate or succinate, and I can explain whether those symptoms could be medication-related.
