Had Botox 2 months ago for masseter hypertrophy. I'm now two weeks pregnant and worried?

In your case since you had the botox treatment 2 months ago you should not be worries. Botox is not recommended during pregnancy as there hasn't been any studies carried out on pregnant woman. As stated previous botox doesnt go systemic and it works inside the muscle

Botox has not been studied in women who are pregnant, however, many of my patients have had treatment without knowledge of their pregnancy and had no issues. The medication is not absorbed into the body at cosmetic doses and is only effective locally. Best, Dr. Emer

I would not be concerned that you had Botox two months ago and are now 2 weeks pregnant.  There should not be any effect to your unborn child.  

Hi, and thank you for your query. As there are no large scale studies into the effects of Botox during pregnancy, we cannot say for absolute sure. However, there is an acceptance within the plastic surgery community that there is little to no chance that the Botox will travel far enough to have any effect whatsoever on the foetus, because it is injected locally into the muscle, not into the bloodstream. Of course, it is not advisable to undergo cosmetic treatments whilst pregnant, and I would suggest that you speak with your obstetrician who will be able to answer any further queries you may have, but I wouldn't worry. Congratulations on your pregnancy, and all the best for the future! 

Although there have never been any real clinical studies regarding pregnancy and Botox there are many instances of pregnancy and Botox without any problems. also the Botox given 2 months ago is actually out of your system.  It is depositied and works only locally and does not disseminate throughout the body. There will be no effect on you or the baby

Thank you for sharing your question. The Botox you had 2
months ago is most likely out of your system by now. Additionally, there has been
no clinical evidence that having Botox can harm a fetus. With that said, Botox
is not recommended during pregnancy. You should also feel free to discuss these
questions with your OBGYN and your injector. For now, you can rest easy that
your prior Botox injections have not harmed your baby in anyway. Best, Dr.
