I always wonder when the description says “may cause liver damage” just how much and how bad?
Tylenol in high doses is extremely harmful on the liver --especially for people who consume a lot of alcohol.
I've known people who drink Nyquil to get a buzz. What they don't realize is that each cap of Nyquil contains something like 800-1000mg of Tylenol. Thus, getting "high" from Nyquil will really screw up your liver due to the huge doses of Tylenol.
All this stuff - tylenol and advil - is very dangerous in certain conditions that are not widely known.
Our friend drank moderately but took Tylenol regularly. The coroner said her liver was worse than someone that drank a qt of hard liquor a day.
Another friend - just last week - developed a flu like condition and did not eat for 3 days but took several advil, nyquil, etc. HIS KIDNEYS SHUT DOWN and the Dr said it was the OTC drugs on an empty stomach.
