There are people who don't know that Tylenol and acetaminophen are the same thing. That is not a reason for us to make everyone's quality of life and access to healthcare worse because some people are ignorant.

It used to be true that doctors could tell people that it was okay to take [X] brand drug with [Y] brand drug but anymore, there are a half dozen formulations of each in varying combinations on the shelf and half of them have some of the same ingredients. Basically every brand has a "fuck it lets just mix everything together, flu" version on the shelf now.
