Did any of you know the epidural contains fentanyl? I didn't know that going into labor. I was shocked and was actually wondering why I felt high from the epidural. Until I looked over and seen the words "fentanyl" on the epidural when it was being replaced. That caused mine and my son's heart rates to drop drastically. My experience with it was almost death. But I would/am doing it again because I can't handle pain. I was just curious if anyone else knew about our epidurals containing fentanyl.
