Ambien is the brand name for zolpidem tartrate, a prescription sleep medication used primarily for the short-term treatment of insomnia, especially difficulty falling asleep. It belongs to a class of drugs called sedative-hypnotics.
Generic name: Zolpidem
Drug class: Non-benzodiazepine hypnotic (“Z-drug”)
Controlled substance (U.S.): Schedule IV
Ambien works by enhancing the activity of GABA (gamma-aminobutyric acid), a neurotransmitter in the brain that slows down neural activity. This calming effect:
Reduces brain alertness
Helps initiate sleep
Shortens the time it takes to fall asleep
Unlike benzodiazepines, zolpidem is more selective for sleep-related GABA receptors, which is why it was developed to reduce next-day sedation (though this can still occur).
Ambien is available in several formulations:
Ambien (Immediate-Release)
5 mg
10 mg
Helps with sleep onset
Ambien CR (Controlled-Release)
6.25 mg
12.5 mg
Helps with sleep onset and sleep maintenance
Other zolpidem forms
Sublingual tablets
Oral spray
Short-term treatment of insomnia
Difficulty falling asleep
Nighttime awakenings (CR version)
Ambien is not intended for long-term nightly use unless closely supervised by a healthcare provider.
(Exact dose must be determined by a doctor)
Adults:
Women: usually start at 5 mg
Men: usually start at 5–10 mg
Older adults (65+):
Lower doses recommended due to fall and confusion risk
Taken once nightly, immediately before bed
Must allow 7–8 hours for sleep
Helps many people fall asleep faster
Often works within 15–30 minutes
Short half-life reduces prolonged sedation compared to older sleep drugs
Lower risk of some benzodiazepine-related effects
Helpful during short-term stress, jet lag, or temporary sleep disruption
Immediate and extended-release options for different sleep patterns
Risk increases with long-term or high-dose use
Stopping abruptly may cause rebound insomnia
Can impair driving, work performance, and focus
Higher risk with Ambien CR or higher doses
Rare but serious effects include:
Sleepwalking
Sleep-driving
Eating or making phone calls while not fully awake
Often with no memory of the event
Because of this, the FDA has issued strong warnings.
Short-term memory issues
Confusion (especially in older adults)
Treats symptoms, not underlying causes
Does not address anxiety, depression, sleep apnea, or lifestyle issues
Drowsiness
Dizziness
Headache
Nausea
Dry mouth
Hallucinations
Mood changes
Depression worsening
Allergic reactions
Ambien should not be combined with:
Alcohol (major risk of respiratory depression)
Opioids
Benzodiazepines
Other sleep medications
These combinations increase the risk of:
Extreme sedation
Breathing problems
Accidents and overdose
Higher risk of falls, confusion, fractures
Lower doses are essential
Not routinely recommended
Use only if benefits outweigh risks
May worsen depression or suicidal thoughts in some individuals
Vs Benzodiazepines: Less muscle relaxation, but still addictive
Vs Melatonin: Stronger effect, higher risk
Vs Antihistamines: Fewer anticholinergic effects but more behavioral risks
Ambien is not ideal for chronic insomnia. Long-term use is associated with:
Reduced effectiveness
Increased dependency risk
Greater side effect burden
Most sleep specialists recommend combining or replacing medication with non-drug approaches.
Cognitive Behavioral Therapy for Insomnia (CBT-I)
Sleep hygiene improvements
Stress management
Consistent sleep schedule
Limiting caffeine and screen exposure
These approaches are often more effective long-term than medication alone.
Fast-acting
Effective for short-term insomnia
Multiple dosage options
Risk of dependence
Memory and behavior side effects
Not suitable for long-term use
Potential next-day impairment
