Twenty years ago or more, the govt forced pharma companies to reduce the amount of Tylenol in pain meds - some used to have upwards of 750 mg Tylenol in each pill. Now they are restricted to 325 mg per pill. No one should take more than 4000 mg per day. Yes, it kills your liver. I can only surmise that since everyone is different, this woman had a higher susceptibility to Tylenol.

Think of it this way. If she took 500 mg Tylenol, 8 alone is 4000 mg.
