alt Hacker NewsI didn’t know this until recently either. I grew up on a family where if there was pain, you just take tylenol to deal with it. We always followed the dosage timing and never had issues. So recently when my wife had some chronic pain I suggested taking tylenol but even after two days the pain would not go away and she went to ER. They did a blood check to see if they could find anything. They didn’t find the cause, just suspected food poisoning, but they found her liver enzymes were near dangerous levels. This was even with timing the dosages absed on instructions. Now I am super careful wtih Tylenol.
Not to chastise you or your wife, there is an actual "Liver Warning" on Tylenol Product labels. They warn against 4000mg/day or with alcohol consumption. It's not an on/off switch, the damage occurs on a ramp that achieves a critical point after so much consumption.
Saying this to encourage label reading and to refute those who might try to characterize your wife's experience as anecdotal. And for those who stop reading a page like this one, after the first paragraph that touts "no evidence": https://www.tylenolprofessional.com/safety-and-efficacy/safe... when at the bottom it reveals the Liver Warning.
