(CNN) - The Food and Drug Administration strengthened warnings about some commonly used sleep aids.
Sleeping pills marketed under the names Lunesta, Sonata and Ambien will require new black-box warnings for potentially dangerous side effects.
There are reports of rare, but serious, injuries and deaths resulting from sleepwalking, sleep-driving and other complex behaviors by people who took the popular drugs.
The FDA said 20 deaths are blamed on the pills.
