There's a campaign aimed at curbing the overuse and even abuse of the pain reliever acetaminophen. It's the Acetaminophen Awareness Coalition's "Know Your Dose" campaign.

Kathleen Wilson, a pediatric nurse who's participating in this year's campaign, says there are some 600 medications with acetaminophen, and many are common. She says people really need to read labels and understand acetaminophen risks. Doctors and pharmacists say any dose over 4,000 milligrams a day is an overdose and can lead to liver damage.
