In brief: TWO

The max recommended adult dose for tylenol (acetaminophen) is 1000mg every 6 hours for no more than 4000mg a day.
Anything more than this will not likely give added pain relief but will increase risk of toxicity, and tylenol (acetaminophen) overdose can be very serious.

The new recommended maximum dosage of Tylenol or acetaminophen is now 3000 mg or a total of 6 extra strength tablets in a day. The maximum single dose is still 1000 mg.

In brief: It depends

Make sure you take tylenol (acetaminophen) or Acetaminophen only as directed by the package.
Generally, you can take up to 1000 mg at a time if you do not have a history of liver disease or are taking medications that interact with or contain Acetaminophen (check the ingredient list on the box--it's present in alot of other medications). No one should not take more than 4000 mg in a 24 hour period.
