It is generally considered unlikely that Botox harms a breastfeeding baby. Botox is injected locally and in small amounts, and research shows only trace or undetectable levels of botulinum toxin in breast milk after treatment. The toxin is a large molecule that probably does not pass into breast milk significantly, and even if trace amounts enter, they are likely broken down in the infant’s gut without harm. Some experts recommend breastfeeding right before receiving Botox and waiting a few hours afterward as a precaution. Studies from 2024 and 2025 found very low to no detectable Botox in breast milk samples of women who received typical cosmetic doses, with no reported adverse effects in infants. Major Botox manufacturers do not recommend it during nursing due to lack of formal studies but advise consulting a healthcare provider. While limited, current evidence suggests Botox injections while breastfeeding carry a very low risk of harm to the infant, but individual consultation with a healthcare professional is essential for personalized advice and monitoring.
