Is it safe to take Metoprolol with Pregnancy?
Metoprolol is a cardioselective beta-blocker occasionally used in pregnancy for cardiac arrhythmias, hypertension, or migraine prevention when labetalol isn't suitable. It crosses the placenta and carries the same class risks as other beta-blockers: neonatal bradycardia, hypoglycaemia, and potential growth restriction. Neonatal monitoring at delivery is needed. Never stop metoprolol suddenly.
How do Metoprolol and Pregnancy interact?
Beta-1 blockade crosses the placenta; metoprolol's cardioselectivity reduces but doesn't eliminate fetal effects. Growth restriction risk is lower than with atenolol in observational data. Neonatal bradycardia and hypoglycaemia documented.

Interaction severity
Rated moderate: metoprolol is genuinely used in pregnancy for specific heart conditions under specialist supervision, though labetalol is generally preferred first-choice, reflecting a real but manageable risk profile rather than a contraindication.
