What This Means
Labetalol transfers only a very small amount (0.07%) of the maternal dose to your baby through breast milk. This is generally considered compatible with breastfeeding. The M:P ratio of 1.70 means the drug concentrates more in breast milk than in blood, meaning more may reach your baby. Consider discussing timing (e.g., taking after a feeding) with your healthcare provider.
Important: This information is for educational purposes only. Always consult your healthcare provider before taking any medication while breastfeeding. Do not stop prescribed medications without medical advice.
