So can you safely try to look ever-youthful while pregnant? In a word: No. "Obviously, there are no adequate controlled studies in pregnant women taking Botox," says Faris Ahmad, M.D., an Ob/Gyn in Troy, Michigan (who also notes that questions about this treatment are becoming more and more common in his office). "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. It also states that, 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." He adds that if you received an injection just prior to or during your first trimester, you certainly should not repeat the injection while pregnant.

And what about after baby arrives? "It is not known whether Botox is excreted in human breastmilk, so women should wait at least until they are finished nursing before considering the medication," says Ahmad. "Not much is known as to how long they should wait postpartum."
