Butorphanol
"I have been stuck in prodromal labor for over two weeks, and after a lot of talking into and lack of sleep, I agreed with my midwife to try 1mg (only half of the normal dose) of stadol with zofran to ensure that I get some rest. Not only did I not rest, but my contractions got stronger (still not productive) and more painful, the room was spinning, and I still threw up for the duration. It kicked up contractions to 2 minutes long with only 30 seconds in between on top of of the vomiting and dizziness. Not to mention that I became very difficult to deal with and talk to at this point. It made a bad and emotionally trying day even worse. I will never use or recommend this drug."
