No, pregnancy and lactation are absolute contraindications for treatment with botulinum toxin. Although there is no evidence that the toxin causes harm to the fetus or infant, no controlled studies have been performed in pregnant or lactating women for obvious ethical reasons. As a precaution and following international medical guidelines, we recommend waiting until the breastfeeding period is completed before resuming botulinum toxin treatments. Your health and that of your baby are always the first priority.
