What do u do if u think u might've accidentally taken 2, 000mgs of tylenol (acetaminophen)??? I just can;t remember but think I might have just now.

Tylenol (acetaminophen) over dose. If you are a healthy person no medical problem and not on any other medication and no alcohol abuse problem, it should be a ok, just do not take anymore tylenol (acetaminophen) for another 24 hrs. A normal person with normal liver should be able tolerate 4 gm/day of Tylenol (acetaminophen).
