FDA Orders Stronger Warning Labels for Ambien, Other Sleep Drugs
March 14, 2007— -- Rosalind Cartwright is no stranger to sleep.
Cartwright, a professor and chair of the department of psychology at Rush University in Chicago, has researched sleep for the past 40 years and written numerous studies on dreams and slumber.
But last September, she experienced a sleep-related anomaly that even she can't entirely explain.
"That night, I have no idea what happened, except that I found myself on the floor at 3:30 a.m.," she says. "I was really hurt badly, but I crawled back into bed and went to sleep."
When she woke up to her alarm three hours later, she discovered that she was bleeding and in serious pain.
She says a trip to the emergency room revealed that during the night she had somehow managed to sustain four pelvic fractures, three broken ribs, a fractured left wrist and a nasty bump on the head that led to bleeding on her brain.
Cartwright says she has neither a personal nor family history of sleepwalking. But she believes that an interaction between the sleeping pill Ambien and an over-the-counter cold medicine she had taken earlier that night caused her to leave her bed and injure herself.
Cartwright's experience, though rare, is not unheard of.
Partly in response to such reports, the U.S. Food and Drug Administration urged sleep drug manufacturers Wednesday to strengthen their package labeling to include warnings of sleep walking, "sleep driving" and other behaviors.
The FDA will also require additional warnings of the potential for allergic reactions with the use of the drugs.
Sleeping pills, in general -- and Ambien, in particular -- have come under increasing scrutiny over the past year.
A class action lawsuit against Sanofi-Aventis, the maker of Ambien, was filed on March 6, 2006, by those claiming that they engaged in a bizarre variety of activities while asleep after taking the drug -- from binge eating to driving their cars while asleep.
And the unusual side effects of the drug made national headlines on May 5, 2006, when Rhode Island Rep. Patrick Kennedy smashed his Ford Mustang into a barrier near Capitol Hill. He later released a statement saying that he had been disoriented by two prescription medications he had taken, one of which was Ambien.
