Popular painkiller can be a killer itself

Popular painkiller can be a killer itself: "Just twice that maximum dose increases your risk of liver failure. The daily maximum equals eight Extra Strength Tylenols, so using 15 pills a day can be dangerous -- even once. The maximum doesn't change if you mix products. Doctors worry some overdoses stem from people who combine several of the 600-plus acetaminophen drugs and don't realize how much they're ingesting."
