Interaction entre Eszopiclone et Hydroxyzine

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 )].

Rarely, cardiac arrests and death have been reported in association with the combined use of hydroxyzine hydrochloride intramuscularly and other CNS depressants.

PRECAUTIONS THE POTENTIATING ACTION OF HYDROXYZINE MUST BE CONSIDERED WHEN THE DRUG IS USED IN CONJUNCTION WITH CENTRAL NERVOUS SYSTEM DEPRESSANTS SUCH AS NARCOTICS, BARBITURATES AND ALCOHOL.

Therefore, when central nervous system depressants are administered concomitantly with hydroxyzine their dosage should be reduced up to 50 percent.

The efficacy of hydroxyzine as adjunctive pre- and postoperative sedative medication has also been well established, especially as regards its ability to allay anxiety, control emesis, and reduce the amount of narcotic required.
