Although injecting Botox directly into the face is considered a fountain of youth for many, it is a big no-no during pregnancy. Botox, derived from the bacterium Clostridium botulinum, works by “preventing nerve impulses from reaching the muscle, causing the muscle to relax,” according to WebMD.

The Physician's Desk Reference states that "the treatment should be administered during pregnancy only if the potential benefit justifies the potential risk to the fetus - i.e., cosmetic reasons would not be justified. If the drug is used during pregnancy, or if the patient becomes pregnant while taking the drug, she should be apprised of the potential risks, including spontaneous abortion [miscarriage] or fetal malformations, which have been observed in rabbits."

If you received an injection just before conceiving or before you knew you were pregnant, tell your doctor right away and don't receive any additional injections during the remainder of your pregnancy. Once your baby is born, you may have to wait a bit longer to resume injections depending on whether you breastfeed or not. Scientists have not yet determined whether Botox can be passed to your baby through breastmilk, so to keep your baby safe, you should wait until you wean your baby completely before you schedule your next injection.
