Ambien (zolpidem) is used to treat sleep problems (insomnia). It may help you fall asleep faster, stay asleep longer, and reduce the number of times you awaken during the night. Zolpidem belongs to a class of drugs called sedative/hypnotics. It acts on your brain to produce a calming effect. This medication is usually limited to short-term treatment periods of 1-2 weeks or less.
Prescriptions for sleeping pills are increasing with Ambien continuing to lead those in its class. Total Benzodiazepoid (benzodiazepine and related drugs) prescriptions in 2001 were 29.2 million. Ambien was prescribed 18 million times, Sonato about 1 million times. In 2006, 43 million benzodiazepoid prescriptions were prescribed, 28 million for Ambien, 1 million for Sonata, 2.3 million for Lunesta (approved March 2005), and 22 million in other benzodiazepines.
A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of sedative/hypnotics. Some of these changes may be characterized by decreased inhibition (e.g., aggressiveness and extroversion that seemed out of character), similar to effects produced by alcohol and other CNS depressants. Visual and auditory hallucinations have been reported as well as behavioral changes such as bizarre behavior, agitation and depersonalization.
There have been reports of people getting out of bed after taking a sedative-hypnotic and driving their cars while not fully awake, often with no memory of the event. If a patient experiences such an episode, it should be reported to his or her doctor immediately, since "sleep-driving" can be dangerous. This behavior is more likely to occur when Ambien is taken with alcohol or other central nervous system depressants. Other complex behaviors (e.g., preparing and eating food, making phone calls, or having sex) have been reported in patients who are not fully awake after taking a sedative-hypnotic. As with "sleep-driving," patients usually do not remember these events.
