A concern with OTC drugs is specifically that they won't be taken at normal doses. People confuse brand names and drug names, and don't realize they are taking more than the reccomended amount. This is especially problematic with combination drugs.
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.
The desire to nanny-state things to the lowest common denominator is ruining everything, and it's a major driver for various problems all the way to the housing crisis and the cost of healthcare in the first place.
Doesn't OTC specifically mean the ones that can't just be on the shelf ? Where you do not need a prescription but a pharmacist still has to be asked to hand it to you "over the counter" ?
