Just as an aside, how many people are regularly slamming huge amounts of Narcan and having their patients wake up flailing and fighting? Do people still really do this?
I've used a lot of Narcan. I worked in Yakima Washington. I used a LOT of Narcan. And in my anecdotal experience, n=1, I have never, ever had an opiate overdose wake flailing and fighting. Normally, after a half milligram of Narcan, they're breathing and if they're starting to wake up, awfully apologetic and embarrassed.
Perhaps a bit more careful titration is in order?
