My next door neighbor is a Pharmacist. He says you see it very rarely in clinical context. At nearly 100x more powerful than morphine, he equates it to trying to carefully crack an egg with a sledgehammer. The few times he does see it is usually end of life pain management.
(Context - I’m a medical underwriter, we talk about these things.)
$hit. I've been on Fentanyl for a year now. Oh well, been nice knowing everyone.
