The dose of zaleplon should be individualized. The recommended dose of zaleplon for most nonelderly adults is 10 mg. For certain low weight individuals, 5 mg may be a sufficient dose. Doses above 20 mg have not been adequately evaluated and are not recommended.
Elderly patients and debilitated patients appear to be more sensitive to the effects of hypnotics, and respond to 5 mg of zaleplon. The recommended dose for these patients is therefore 5 mg. Doses over 10 mg are not recommended.
Patients with mild to moderate hepatic (liver) impairment should be treated with zaleplon 5 mg because clearance is reduced in this population. Zaleplon is not recommended for use in patients with severe hepatic impairment.
An starting dose of 5 mg should be given to patients taking cimetidine because zaleplon clearance is reduced in this population.
If you take too much zaleplon, call your doctor or poison control center right away, or get emergency treatment.
