As sedative when used hydroxyzine preco as premedication and following general hydroxyzine pamoate anesthesia, hydroxyzine may potentiate meperidine and barbiturates, so their use in pre-anesthetic adjunctive therapy should be modified on an individual basis.

As sedative when used as premedication and hydroxyzine pamoate use in cats following general anesthesia, hydroxyzine may potentiate meperidine and barbiturates, so their use in pre-anesthetic adjunctive therapy should be modified on an individual basis. Although, both hydroxyzine and cetirizine act as antihistamines, hydroxyzine causes more sedation than cetirizine.
