The Oregonian, "Popular painkiller [Acetaminophen] can be a killer itself"

Experts warn against [Acetaminophen] overdosing, now the No. 1 cause of death in poison-control cases and acute liver failure

          Plagued by nagging colds, sore backs, throbbing heads and life's other aches and pains, millions of people reach for Tylenol. And if one dose doesn't stop the pain, maybe two or three will. If you do that, you're courting trouble: An overdose of acetaminophen, the popular painkiller in Tylenol and other brands, sends thousands of U.S. residents to the hospital each year, killing hundreds.
          For years, fear of an acetaminophen overdose has been the main reason people call poison control centers. It's the leading cause of death in poison-control cases. Now, studies show overdoses of the drug have become the nation's chief cause of acute liver failure, a rare but life-threatening crisis. Up to half of these poisonings appear accidental.
          The federal government is considering more severe warning labels on over-the-counter acetaminophen drugs. Some brands have already made changes. And drug makers and regulators have launched campaigns to warn about the dangers of acetaminophen overdoses. Just twice that maximum dose increases your risk of liver failure.
