It is even worse than what you think it is:

So I happen to not physically be in America and I was not aware that paracetamol and acetaminophen are the same thing when the doctor asks me if I have taken any Panadol (what? Paracetamol)... so I say no and he proceeds to start pumping a thousand milligrams plus directly into my veins. Yeah, but I had taken Tylenol and some cold medications, which combined, had placed over a thousand milligrams of acetaminophen into my system previously. A thousand milligrams of acetaminophen here, a thousand milligrams of paracetamol there. Another thousand in rounding errors and a continuous drip into my veins... Who cares right?
Needless to say, my liver goes, "WTF dude?" and 6 months of hell proceed to occur. Some Milk Thistle and time allowed everything to more or less return to normal.
Yeah. It should be illegal to put that shit into ANY product other than one distinctly labelled as acetaminophen aka paracetamol. It should not be labelled Cold Medicine or Cough Medicine, or Muscle Relaxer or whatever the fuck else. That stuff is DANGEROUS. I do not want to have a liver transplant merely because of differing naming conventions and added ingredients.
