Zolpidem (marketed as Ambien®, Intermezzo®, etc.) – 10 mg dose
Zolpidem is a non‑benzodiazepine hypnotic (often called a “Z‑drug”) used to treat short‑term insomnia. The 10 mg formulation is the maximum recommended dose for most adults and is typically taken once at bedtime.
1. Typical dosing and administration
| Population |
Usual dose |
Notes |
| Adults |
10 mg (tablet or orally disintegrating tablet) |
Take immediately before sleep. Do not take more than 10 mg or more than once per 24 h. |
| Elderly (≥65 yr) |
5 mg (tablet) or 5 mg ODT |
Start lower due to higher sensitivity, increased risk of next‑day sedation, and more pronounced side effects. |
| Pregnancy |
Avoid |
Category C; risk to fetus is unknown and generally not recommended. |
| Breastfeeding |
Avoid |
Drug is excreted in human milk and may affect nursing infants. |
Important: The 10 mg tablet is meant for short‑term use (usually 4–6 weeks). Longer therapy can lead to tolerance, dependence, and withdrawal symptoms.

| Antidepressants (SSRIs, SNRIs, tricyclics) |
↑sedation / ↑plasma levels |
Monitor closely; dose adjustment may be needed. |
| CYP3A4 inhibitors (ketoconazole, ritonavir, fluconazole) |
↑ zolpidem levels |
Consider lower dose (e.g., 5 mg). |
| CYP3A4 inducers (rifampin, carbamazepine) |
↓ efficacy |

Tip: Always inform your prescriber about all medications, supplements, and herbal products you’re taking.
4. Contraindications / cautions
- Severe hepatic impairment – zolpidem is metabolized by the liver; use with caution or avoid.
- Severe renal impairment – may increase exposure; avoid or monitor dose.
- History of substance abuse or addiction – risk of misuse is higher.
- Pregnancy / lactation – generally contraindicated.
- Elderly – increased sensitivity to next‑day residual effects.
5. What to do if you miss a dose
- If you miss a dose: skip it and resume next scheduled dose. Do not double up to “catch up”.
- If you accidentally take a second dose: Monitor for excessive sedation or dizziness; do not drive or operate machinery.
6. Withdrawal / discontinuation
Abrupt discontinuation after prolonged use may cause rebound insomnia, anxiety, or agitation. A gradual taper (reducing the dose by 1–2 mg every 1–2 weeks) is usually recommended.
7. Bottom line
- 10 mg is the standard adult dose for insomnia; 5 mg is typically used in the elderly or to reduce side‑effects.
- Use short‑term only; long‑term use is discouraged due to tolerance, dependence, and the risk of complex sleep behaviors.
- Avoid alcohol, monitor for next‑day sedation, and inform your prescriber of all other medications.
If you’re considering starting, changing, or stopping zolpidem, please talk with your healthcare provider to ensure it’s safe for your specific health situation.
