Zolpidem, sold as Ambien and Ambien CR among other brands, is a prescription sedative-hypnotic used for short-term treatment of insomnia. It acts on the same GABA-A receptor system as benzodiazepines but binds more selectively, which is why it induces sleep with less of the anti-anxiety and muscle-relaxant effect of older drugs.
Two regulatory changes define how zolpidem should be prescribed today. In 2013 the FDA lowered the recommended dose for women, because women clear the drug more slowly and morning blood levels high enough to impair driving were common at the older dose. In 2019 the FDA added a boxed warning for complex sleep behaviors, including sleepwalking, sleep-driving, and other activities performed while not fully awake, after reports of serious injuries and deaths.
The guides in this library cover dosing by age and sex, monitoring, interactions, discontinuation, cost and coverage, and how zolpidem compares with alternatives like trazodone, eszopiclone, and the newer orexin antagonists.

Common questions about Zolpidem
What is the correct zolpidem dose?
Current FDA labeling recommends 5 mg for women and 5 to 10 mg for men for immediate-release zolpidem, taken immediately before bed with at least 7 to 8 hours of sleep available. Older adults and people with hepatic impairment are started at the lower dose. Your prescriber sets the dose; do not adjust it yourself.
Why is the zolpidem dose lower for women?
Women eliminate zolpidem more slowly, so the same dose leaves higher morning blood levels. In 2013 the FDA lowered the recommended dose for women after driving-simulation and blood-level data showed next-morning impairment was common at the older dose.
What is the zolpidem boxed warning?
Since 2019, zolpidem carries a boxed warning for complex sleep behaviors: sleepwalking, sleep-driving, and doing other things while not fully awake, sometimes with serious injury or death. Any such episode is a reason to stop the drug and contact your prescriber, not to lower the dose and continue.
Is zolpidem addictive?
Zolpidem is a Schedule IV controlled substance with real potential for tolerance, dependence, and rebound insomnia after stopping. It is intended for short-term use, and longer courses should be a deliberate clinical decision with a plan for reassessment rather than an open-ended refill.
How long does zolpidem stay in your system?
Immediate-release zolpidem has a short half-life of roughly 2 to 3 hours in most adults, which is why it helps with falling asleep more than staying asleep. Clearance is slower in women, older adults, and people with liver impairment, so next-morning effects can persist even when the drug feels worn off.
What should not be combined with zolpidem?
Alcohol and other central nervous system depressants, including opioids, benzodiazepines, and sedating antihistamines, meaningfully raise the risk of severe sedation and respiratory depression. Strong CYP3A4 inhibitors can raise zolpidem levels. Review your full medication list with your prescriber or pharmacist before starting.
