From the Eszopiclone (Lunesta) label · effective 2025-01-08
The use of LUNESTA with other sedative-hypnotics at bedtime or the middle of the night is not recommended.
Risk increases with dose and use with other CNS depressants and alcohol.
Post-marketing reports have shown that complex sleep behaviors may occur with LUNESTA alone at recommended dosages, with or without the concomitant use of alcohol or other CNS depressants [see Drug Interactions ( 7.1 )] .
Additive effects occur with concomitant use of other CNS depressants (e.g., benzodiazepines, opioids, tricyclic antidepressants, alcohol), including daytime use.
…psychomotor impairment is increased if LUNESTA is taken with less than a full night of sleep remaining (7- to 8 hours); if higher than the recommended dose is taken; if coadministered with other CNS depressants; or coadministered with other drugs that increase the blood levels of eszopiclone [see Dosage and Administration ( 2.3 ) and Clinical Studies ( 14.3 )].
