Based on that, the FDA advisory panel voted 21-16 Tuesday to lower the maximum daily dose of nonprescription acetaminophen, which is currently 4 grams - equal to eight pills of a drug such as Extra Strength Tylenol. The panel was not asked to recommend another maximum daily dose.

"The usual dose that people take probably ought to be lower in order to insure a greater margin of safety should people take more than is recommended on the label," she said. "That message was pretty clear."
"There was a clear message that there is a high likelihood of overdose from prescription narcotic/acetaminop
