Ambien is the most commonly prescribed sleep-aid in the United States.  Ambien is indicated in the treatment of insomnia.  It is recommended for short-term use only, typically 7-10 days.  A doctor may advise further use up to a month, but rarely any longer.  Ambien has a low occurrence of side effects, which are typically mild.  When starting an Ambien prescription, you should take great care when engaging in activities requiring sharp awareness, such as driving a car, operating machinery, etc. until you know how your body will react to the medication.
