Some Sleep Drugs Do More Than Make You Sleep
The United States Food and Drug Administration has ordered companies to place strong new warnings on thirteen drags that treat sleep disorders. It also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drags.
Last Wednesday, the FDA announced that some of these drugs can have unexpected and dangerous effects. These include the risk of life-threatening allergic reactions. They also include rare incidents of strange behavior. These include people cooking food, eating and even driving while asleep. The patients later had no memory of doing these activities while asleep.
Last year, a member of the United States Congress said he had a sleep-driving incident. Patrick Kennedy, a representative from Rhode Island, crashed his car into a security barrier near the building where lawmakers meet. The accident happened in the middle of the night and no one was hurt. Mr. Kennedy said he had earlier taken a sleep medicine. He said he was also being treated with a stomach sickness drug that could cause sleepiness.
The Food and Drug Administration did not say in its announcement how many cases of sleep-driving it had documented. However, the New York Times4 reported last year about people who said they had strange sleep events after taking the drug Ambien. Some reported sleep-driving and sleep-walking. Others said they found evidence after waking in the morning that they had cooked food or eaten in their sleep. But they had no memory of carrying out the activities.
A Food and Drag Administration official says that these serious side effects of sleep disorder drugs appear to be rare. But, he also says there are probably more cases than are reported, s He says the agency believes the risk of such behaviors could be reduced if people take the drugs as directed and do not drink alcohol while taking the drugs. The Food and Drug Administration has advised drug companies to carry out studies to investigate the problem.
There are altogether 13 drags treating sleep disorders in the United States.
