Botox during pregnancy

There is little evidence that regional Botox will spread systemically (meaning through the bloodstream) to your uterus. Therefore, I don't believe that there is any cause for concern. Some recent recports suggested that Botox may spread centrally to your brain via the nerves, but this would not effect your baby and the consequence of this is unknown and felt to be of relatively little import.

As all have suggested, notify your OB but it is likely that nothing more would need to be done. There is no test. By the way, Botox has been used on newborns for management of severe neck spasms causing a condition called Torticollis.
