Earlier quoted context omitted.
acetaminophen is often put in medications because it's toxic. It's there to dissuade people from *gasp* taking too much and possibly experiencing some positive feelings or enjoyment that offends the sensibilities of decision makers. Better that we destroy a few people's livers than that those people get a buzz. (to be clear, this last sentence is not my view. I'm mocking that view)
This also is silly, illegal drug users constantly take their dosages mixed with much worse things than Tylenol with no noticeable dissuasion effect that I am aware of. Acetaminophen is mixed with oxycodone etc bc it increases the pain relieving effect of the opiate drug (which for many people (e.g. me), are of limited effectiveness relative to the side effects/"buzz"), and because, unlike NSAIDs, it doesn't thin your…
Also, we need to really research the NSAIDS after surgery thing, afaik, there has been nothing super rigorous on it and is only going off of the common knowledge that they do thin blood. I do not like Tylenol and my partner is allergic, we’ve both broken the rule about nsaids post surgery.
