What is zolpidem?
Zolpidem is a medicine used to treat insomnia. The active ingredient is zolpidem tartrate.
In the United States, zolpidem is available under several brand names, including Ambien, Ambien CR, Edluar, Intermezzo, and Zolpimist.
How zolpidem works
Zolpidem acts on central receptors in the GABA-omega receptor complex and helps modulate the opening of chloride ion channels. In practical terms, it is used as a sleep medicine.
What zolpidem is used for
The main use described in the source content is insomnia in adults, especially when sleep problems limit daily activity or create significant stress.
Whether zolpidem is appropriate depends on the person’s overall health, other medicines, and the reason for the sleep problem.
How zolpidem is taken
Zolpidem is taken immediately before going to bed or while already in bed. The source content notes that it should not be taken again during the same night.
Because this medicine can cause sleepiness and reduced alertness, timing matters. The official leaflet should always be checked for the exact instructions for the specific product.
Dosage information in the source content
| Group | Information provided |
|---|---|
| Adults | Recommended dose: 10 mg/day before bedtime |
| Elderly or weakened patients | 5 mg |
| Liver failure | 5 mg; total dose should not exceed 10 mg |
| Treatment duration | Do not exceed 2 weeks; maximum 4 weeks including gradual withdrawal |
Important: These details come from the original content and may not apply to every zolpidem product. Always verify the exact dose and duration in the official leaflet for the specific medicine prescribed or dispensed.
Who should not use zolpidem according to the source content
The original content lists the following contraindications:
- Hypersensitivity to zolpidem
- Myasthenia gravis
- Sleep apnea syndrome
- Severe liver failure
- Acute and/or severe respiratory failure
Warnings and precautions
Zolpidem requires caution in older adults, people with respiratory problems, liver problems, psychotic illness, depression, or a history of alcohol or drug abuse.
The source content also highlights several important risks:
- Anterograde amnesia
- Psychiatric or paradoxical reactions, especially in older adults
- Sleepwalking
- Reduced consciousness, which may increase the risk of falls and serious injury
- Tolerance and dependence after continued use
- Withdrawal symptoms if treatment is stopped suddenly
The source also notes that zolpidem should not be used for anxiety associated with depression or as the primary treatment for psychotic illness.
Liver and kidney considerations
Liver failure
Zolpidem is contraindicated in severe hepatic insufficiency in the source content because it may precipitate encephalopathy. In hepatic insufficiency, the source notes caution and a 5 mg dose.
Kidney failure
The source content says to use caution, but that dosage adjustment is not necessary.
Drug and alcohol interactions
Zolpidem may enhance the depressant effect of the central nervous system when used with:
- Neuroleptics
- Hypnotics
- Anxiolytics or sedatives
- Antidepressants
- Narcotic analgesics
- Antiepileptics
- Anesthetics
- Sedating antihistamines
The source content also notes:
- Reduced effect with CYP3A4 inducers such as rifampicin
- Increased plasma concentrations with CYP3A4 inhibitors such as ketoconazole
- Enhanced sedative effect with alcohol
Pregnancy and breastfeeding
The source content says there is not enough data to assess safety in pregnancy and that zolpidem should be avoided during pregnancy, especially in the first trimester.
It also states that zolpidem should not be given during breastfeeding because benzodiazepine-like agents are excreted in breast milk.
Driving and operating machinery
Zolpidem can impair reaction time, concentration, and memory. Drowsiness may continue the next morning after taking it.
The source content advises not to drive or operate machinery requiring special attention or concentration until at least 8 hours after taking the medicine.

- The exact brand and formulation

- Warnings about alcohol and other sedating medicines
- Instructions for older adults or people with liver problems
