I have been an ICU nurse for a few years now, and cannot keep Levo and Neo straight. We use them both a lot, and I keep thinking Levo is phenyl and that Neo is Norepi. I mean I understand the difference in the 2, but in an emergency, when someone orders Levo, I cannot remember if that is Norepi or Phenyl. I feel stupid for having to look it up every time but cannot keep the Levo/Neo/Phenyl/Norepi thing straight. I was wondering if anyone had any tricks to keep them straight in my mind. Thank you very much.
