I had 8 units botox at 11 weeks pregnant in the corner of my eyes. How harmful is this to my baby?

While there are no studies that address the effects of Botox on developing fetuses, it still should be avoided during pregnancy and nursing. That said, there is no reason to be alarmed. I have never heard of any ill effects on a fetus or baby from Botox and many women have made the same “mistake” that you have. Be assured, only very small doses of Botox are present in 8 Units. Enjoy your pregnancy and don’t worry. I hope this helps.

Congratulations on your new baby to be! There is no evidence that Botox can cause any harm to your baby. Botox is a local treatment that affects just the muscle into which it is injected. The amount of active ingredient is very small and it does not circulate in your blood. The use of Botox has never been studied in pregnant women so it is NOT approved for use in pregnant women.  But, many women have had Botox while pregnant and have suffered no adverse effects. We recommend to wait until after you’ve finished nursing before getting another treatment — just to be safe. Please consult a board-certified dermatologist when you’re ready for anti-aging treatments again. 

Currently there are no studies to show the effects of botox on pregnancy. Botox is localized into the muscle and women have gotten the treatment before unknowing they were pregnant with no complication. I would let your OBY/GYN know that you got injected. However your injector should have asked you of any changes in health during your appointment.
