I got Botox a month ago and just found out I am pregnant. Should everything be OK?

First of all, congratulations! I am literally writing this from the hospital room where my 3rd child was born yesterday. Do not worry, your baby will be fine. Botox has been in therapeutic use since 1968 without any reported issues in pregnancy. A publication looking at a small group dealing with this also showed no issue. I know several women personally who are in "the business" and continued Botox through pregnancy, although that is not the norm. Any respectable injector would never treat a pregnant patient, but most would agree that doing so would likely be safe. The way that botulinum toxin injures infants has to do with paralyzing the diaphragm and causing breathing issues, but you are doing that for you baby right now. Relax and enjoy!

But it does happen.  There is a small study regarding this issue that suggested there were no problems but I stress the study was small.  The lack of information is the reason.  Ultimately you should seek advice from your personal doctors if you feel you need to make more sense of the lack of certainty. 

Although there are no studies directly evaluating the association between botox and the fetus, I will tell you that my own wife has had Botox within 4 weeks of her pregnancy and we have two beautiful healthy boys and no complications.  From the perspective of your botox, you have little to worry about regarding your baby.  Unfortunately, I don't think there will be any physician you can find that can give you hard data on this matter since there is none.  Best of luck!
