Botulinum Toxins, Therapeutic

2006

Abstract

Of the therapeutically used botulinum toxins, only onabotulinumtoxinA has been studied during breastfeeding and only in cosmetic doses. It was not detectable in the milk of two women and detectable in only minute amounts in 5 others after 40 to 92 units injected into the face. A systematic review found that among 94 cases of reported breastfeeding, no adverse infant events or developmental delays were observed at 1 year.[1] International guidelines considers onabotulinumtoxinA acceptable in breastfeeding women with chronic migraine, and it is often used in nursing mothers by dermatologists, including dermatologists themselves.[2-4] High doses for other conditions have not been studied.
