After getting reports of hundreds of driving-related incidents and accidents involving sleeping pills like Ambien that contain the drug Zolpidem, the Food and Drug Administration is ordering drug makers to cut the dosage in half for women, from 10 to 5 milligrams.

Compounding the problem: women metabolize sleeping pills differently than men. NBC's Tom Costello reports. (Nightly News)
