===Fentanyl===
===Fentanyl===
Fentanyl may be used i/v or via slow release patches for severe pain. It is a full OP3 agonist with a rapid onset of action and a duration of 15-20 mins. It is therefore useful as "rescue analgesia" to top-up levels of analgesia during particularly painful stages of surgery. It is an unlicensed, Schedule 2 controlled drug.
