That's such a weird perspective to take. No information, including the exact dosage that will kill you, should be hidden "just in case". It's like security by obscurity of medical world. In fact I'd advocate that every paracetamol packet should say, in big letters in the back "TAKING X OF TABLETS WILL KILL YOU WITH NO KNOWN TREATMENT, AND IT WILL HURT ALL THE TIME AS YOU'RE DYING". There's so many people who don't realize how easily taking too much paracetamol can kill it's crazy.
Yeah, exact dosage is irrelevant. If you're going to kill yourself, you just take a few packs. As you say and has been said elsewhere in here, the dosage difference between therapeutic and fatal is really small, so if you take multiple times the normal dosage, well... you don't need exact dosage for that.
France: buying paracetamol can be done freely here ,but it has to be asked for at pharmacies, and the dangerous dosage (4000mg/day) is heavily stressed.
Also, it is written on the instruction manual, in quite big letters.
