In one single dose, how much acetaminophen (Tylenol) does it take to pose a threat of liver damage in a healthy adult?
The recommendation is no more than 4,000 mg (4 grams) of acetaminophen (Tylenol or Paracetamol) per 24 hour period. But how many milligrams can a single dose contain if you don’t take any more that day? Would 4,000 mgs. be just fine in a single dose if you took no more for days afterward? Or would that be enough to trigger hepatotoxicity?
