How Long Should I Wait to Get Botox After Pregnancy?

No. Botox is not safe if you are still breastfeeding. Even though only tiny amounts of Botox are injected, there is no data available on whether it goes into breast milk or not. The use of BOTOX® during lactation is not recommended.
Botox is not safe to use during the pregnancy. Some animal studies have shown that Botox causes harm to the fetus during pregnancy. BOTOX® treatment should not be used during pregnancy unless the benefits clearly outweigh the potential risks. This is not the case for using Botox for cosmetic purposes.

Thank you for the question.

Botox has not been tested in pregnancy or breastfeeding.  It is best to avoid it during pregnancy and breastfeeding.
As always, an in-person consultation with a board certified dermatologist with cosmetic training is the best way to assess your needs and provide medical advice. 

Thank you for your question. I would not worry too much if you had Botox and found out you were pregnant. Botox works locally where it was injected and the dosing is very small. The makers of Botox would never consider sponsoring a study to see the safety of Botox 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 Botox treatment during pregnancy so they are aware.
