TIME.com: The FDA's Painkiller Warning: How to Avoid Taking Too Much -- Page 1: "According to Dr. Charles Cain, director of anesthesia at New York Presbyterian Hospital, it's not that hard to reach these danger levels. The average adult should not exceed 4g of acetominophen a day. If someone is taking two extra-strength tablets of Tylenol, which are 500 mg each, every four hours (instead of the recommended every six hours), and then adds a few doses of a cold medication during the day, then they're easily reaching about 4g-6g of acetominophen a day. Do that over a few days, says Cain, and you could damage your liver. Since most people are on several different types of medications already, the liver may be more vulnerable to danger when it's hit with an excess of acetominophen to process. And that's even before the glass of wine or bottle of beer that many of us like to have at the end of day; alcohol also puts the liver to work, and the combination of everything at once may be the perfect storm that sends the liver into failure."
