Would Dysport Have Any Adverse Effect on Pregnancy?

Thank you for your question. I would not worry too much if you had Dysport and found out you were pregnant. Dysport works locally where it was injected and the dosing is very small. The makers of Dysport would never consider sponsoring a study to see the safety of Dysport during pregnancy or breast feeding as it would be too risky for them. Likewise, for physicians. I generally provide reassurance for situations like yours and I do recommend that you stop any future injectable treatments until either the baby is born and after breast feeding. I would also let you OB know that you had a Dysport treatment during pregnancy so they are aware.

Although no adverse effects on the fetus or baby have been reported, neither Dysport nor Botox is recommended while pregnant or while breastfeeding. 

It is not recommended that Dysport be used in woment who are pregnant or breastfeeding. I would not inject Botox, Dysport, or any filler until after a women has finished breastfeeding.
