AbobotulinumtoxinA Breastfeeding Warnings

Safety has not been established. Excreted into human milk: Unknown Excreted into animal milk: Data not available

No data exist on the medical use of this drug during breastfeeding. However, one infant was safely breastfed during maternal botulism and no botulinum toxin was detectable in the milk or infant. Since the doses used medically are far lower than those that cause botulism, amounts ingested by the infant, if any, are expected to be insignificant and not cause any adverse effects in breastfed infants. No special precautions are required.
