Summary of Use during Lactation:
No data exist on the medical use of
botulin B (botulinum toxin) during breastfeeding. However, one infant was safely breastfed during maternal botulism and no botulinum toxin was detectable in the mother's 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.

Type A botulinum toxin was detected in the woman's blood and stools. No botulinum toxin was detected in the infant's blood or stool on the day the mother was admitted to the hospital and no botulism organisms were detected in the infant's stools. The mother was given 2 vials of trivalent botulism antitoxin, 1 intravenously and 1 intramuscularly. A milk sample obtained 4 hours after administration of the antitoxin had no detectable botulinum toxin nor botulism organisms.[1]
