Interaction entre Hydroxyzine et Zaléplone

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.

The use of zaleplon with other sedative-hypnotics at bedtime or the middle of the night is not recommended (see ).

Post-marketing reports have shown that complex sleep behaviors may occur with zaleplon alone at recommended dosages, with or without the concomitant use of alcohol or other central nervous system (CNS) depressants.

Coadministration with other CNS depressants (e.g., benzodiazepines, opioids, tricyclic antidepressants, alcohol) increases the risk of CNS depression.

Dosage adjustments of zaleplon and of other concomitant CNS depressants may be necessary when zaleplon is administered with such agents because of the potentially additive effects.

The risk of next-day psychomotor impairment, including impaired driving, is increased if zaleplon is taken with less than a full night of sleep remaining (7 to 8 hours); if a higher than the recommended dose is taken; if coadministered with other CNS depressants or alcohol; or if coadministered with other drugs that increase the blood levels of zaleplon.
