AbobotulinumtoxinA Breastfeeding Warnings

Benefit should outweigh risk Excreted into human milk: Unknown Excreted into animal milk: Data not available

No data exist on the medical use of this drug during breastfeeding, although medical use is not expected to produce measurable blood levels and therefore it would not be expected to be available for secretion into breast milk. There is a report of a mother who contracted botulism and successfully breastfed her infant. On admission to the hospital, type A botulinum toxin was detected in her blood and stools; none was detected in the infant's stools. The mother was treated with 2 vials of trivalent botulism antitoxin (IV and IM). A milk sample obtained 4 hours after administration of the antitoxin had no detectable botulinum toxin or botulism organisms.
