The information is not intended to cover all possible uses, directions, precautions, drug interactions or adverse effects, nor should it be construed to indicate that use of a particular drug is safe, appropriate or effective for you or anyone else.

For the average healthy adult, the recommended maximum dose of acetaminophen during a 24-hour period is 4 grams (4000 mg) or eight extra-strength tablets. (Each extra-strength tablet contains 500 mg, while each regular strength tablet contains 325 mg.) Among children, the dose of acetaminophen is determined on the basis of each child's weight and age, explicitly stated in the package insert. If these guidelines for adults and children are followed, acetaminophen is safe and carries essentially no risk of liver injury. A person who drinks more than two alcoholic beverages per day, however, should not take more than 2 grams (2000 mg) of acetaminophen over 24 hours, as discussed below, since alcohol makes the liver susceptible to damage from lower doses of acetaminophen.
