Stilnox (zolpidem tartrate)
is indicated for the short-term treatment of insomnia characterized by difficulties with sleep initiation. AMBIEN has been shown to decrease sleep latency for up to 35 days in controlled clinical studies [see Clinical Studies].
The clinical trials performed in support of efficacy were 4-5 weeks in duration with the final formal assessments of sleep latency performed at the end of treatment.
DOSAGE AND ADMINISTRATION
Dosage In Adults
Use the lowest effective dose for the patient. The recommended initial dose is 5 mg for women and either 5 or 10 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 5 mg dose is not effective, the dose can be increased to 10 mg. In some patients, the higher morning blood levels following use of the 10 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 should not exceed 10 mg once daily immediately before bedtime. AMBIEN should be taken as a single dose and should not be readministered during the same night.
The recommended initial doses for women and men are different because zolpidem clearance is lower in women.
Elderly or debilitated patients may be especially sensitive to the effects of zolpidem tartrate. The recommended dose of AMBIEN in these patients is 5 mg once daily immediately before bedtime [see WARNINGS AND PRECAUTIONS, Use In Specific Populations].
Patients with mild to moderate hepatic impairment do not clear the drug as rapidly as normal subjects. The recommended dose of AMBIEN in these patients is 5 mg once daily immediately before bedtime. Avoid AMBIEN use in patients with severe hepatic impairment as it may contribute to encephalopathy [see WARNINGS AND PRECAUTIONS, Use In Specific Populations , CLINICAL PHARMACOLOGY].
Use With CNS Depressants
Dosage adjustment may be necessary when AMBIEN is combined with other CNS-depressant drugs because of the potentially additive effects [see WARNINGS AND PRECAUTIONS].
