Respiratory issues: bronchospasm or worsening asthma/COPD
Liver issues: jaundice, abnormal liver function tests
Neurological symptoms: confusion, hallucinations, memory loss, dizziness leading to fainting
Special Considerations
Blood sugar effects: Metoprolol can mask early symptoms of hypoglycemia in diabetics, such as rapid heartbeat or tremors, increasing the risk of severe low blood sugar episodes
1
Medication discontinuation: Stopping metoprolol abruptly can trigger chest pain, angina worsening, or heart attacks, especially in patients with coronary artery disease. Dose reductions should be gradual under medical guidance
2
Interactions with other medications: Combining with other beta-blockers, calcium channel blockers, or drugs affecting heart rate may increase risks like bradycardia or hypotension
1
Elderly patients: May experience more pronounced dizziness or fatigue due to age-related changes in liver or kidney function

Tips for Managing Side Effects
Change positions slowly to reduce dizziness or fainting
Take the medication with food to improve tolerance
Report persistent fatigue, shortness of breath, swelling, or chest pain to your healthcare provider
Regularly monitor blood pressure, heart rate, and for signs of worsening heart failure or hypoglycemia
For mild rashes or itching, topical antihistamines or creams may help, but consult your doctor if severe
In summary, while metoprolol is generally well-tolerated, patients should be aware of both mild and serious side effects, especially cardiovascular, respiratory, and neurological changes. Regular follow-up with a healthcare provider is essential for safe use
