Atarax - Hydroxyzine hydrochloride

Although the hydroxyzine ethylenediamines, Atarax and Vistaril, are not usually classified with the ethylenediamine antihistamines it should be noted that the formula of Atarax (hydroxyzine hydrochloride) is l-p-chlorobenzyhydryl-4,2 (2(2-hy-Avo yQihoxy)tihy )diethylenediamine dihydrochloride. It therefore would be prudent to avoid the use of hydroxyzine antihistamines in individuals with ethylene-diamine sensitivity.
