Tuesday, Dec. 19, 2006 --

They're used every day in America. The shelves of pharmacies are lined with them. And now the Food and Drug Administrations has decided that over-the-counter painkillers such as Tylenol, Motrin, Aleve and Advil should carry much stronger warning labels because the tens of millions of Americans who take them have no idea how dangerous these drugs can be.

According to the FDA, 200,000 Americans are hospitalized every year from overdoses and the side effects of recommended doses of these drugs, and they cause thousands of deaths a year.

So tonight we'll tell you (everything) you need to know -- precisely which over-the-counter drugs the FDA is talking about, what the data show about their dangers, what the new warnings will say.

And we'll talk to Dr. Tim Johnson, ABC's "family doctor," about what you should do in light of today's FDA action.

Then we turn to youth -- tender youth, troubled youth. Do you remember what it was like to be 12 years old? The hopes and dreams? The insecurity and awkwardness? The cruelties of other kids, the love of friends, the first stirrings of desire?

ABC's John Berman brings us the story of a fascinating new documentary that focuses on the topsy-turvy, impassioned lives of 12-year-old girls at a private boarding school in Massachusetts.

Finally, farewell to the father of Fred Flintstone, Scooby Doo and so many others. Joseph Barbera was, in his way, an American master. Sure, his medium was "just" animated cartoons.

But he was a gifted, popular storyteller during what many regard as the golden age of animation, when the touch of human hands -- not the click of a computer mouse -- is what drew the characters that came into millions of American homes.

Joseph Barbera died this week at 95, and we pay tribute to his work.

We hope you join us.
