Ambien CR

How Supplied


AMBIEN CR (zolpidem tartrate extended-release tablets) is indicated for the treatment of insomnia characterized by difficulties with sleep onset and/or sleep maintenance (as measured by wake time after sleep onset).

The clinical trials performed in support of efficacy were up to 3 weeks (using polysomnography measurement up to 2 weeks in both adult and elderly patients) and 24 weeks (using patientreported assessment in adult patients only) in duration [see Clinical Studies].


Dosage In Adults

Use the lowest effective dose for the patient. The recommended initial dose is 6.25 mg for women and either 6.25 or 12.5 mg for men, taken only once per night immediately before bedtime with at least 7-8 hours remaining before the planned time of awakening. If the 6.25 mg dose is not effective, the dose can be increased to 12.5 mg. In some patients, the higher morning blood levels following use of the 12.5 mg dose increase the risk of next day impairment of driving and other activities that require full alertness [see WARNINGS AND PRECAUTIONS]. The total dose of AMBIEN CR should not exceed 12.5 mg once daily immediately before bedtime.

The recommended initial doses for women and men are different because zolpidem clearance is lower in women.

Special Populations

Elderly or debilitated patients may be especially sensitive to the effects of zolpidem tartrate. Patients with hepatic insufficiency do not clear the drug as rapidly as normal subjects. The recommended dose of AMBIEN CR in both of these patient populations is 6.25 mg once daily immediately before bedtime [see WARNINGS AND PRECAUTIONS; Use in Specific Populations].

Use With CNS Depressants

Dosage adjustment may be necessary when AMBIEN CR is combined with other CNS depressant drugs because of the potentially additive effects [see WARNINGS AND PRECAUTIONS].


AMBIEN CR extended-release tablets should be swallowed whole, and not be divided, crushed, or chewed. The effect of AMBIEN CR may be slowed by ingestion with or immediately after a meal.
