What This Means
Acebutolol transfers about 2.275% of the maternal dose through breast milk. This is generally considered acceptable, but discussing timing of doses with your healthcare provider may be helpful. The M:P ratio of 9.65 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.
