-Epinephrine freely crosses the placenta and may be teratogenic in some species, but does not appear to be teratogenic in humans.
-In the Collaborative Perinatal Project, there was a statistically significant association between the use of epinephrine during pregnancy and major and minor malformations, including inguinal hernia.
