The current maximum daily dose of Tylenol (acetaminophen) is four grams per day, or 1000mg every six hours. However, a recent study shows that, even at those doses, some patients can get higher levels of liver enzymes, an early sign of liver damage.
Acetaminophen is contained in hundreds of pain and cold medications, notably Percocet (oxycodone/apap) and Vicodin/Lortab (hydrocodone/apap). Pharmacists and doctors should emphasize that patients should only take as much medicine as they need — and never more than four grams per day.
