It significantly reduces the occurrence, severity, and duration of hives and significantly reduces pruritus. Cetirizine hydrochloride is contraindicated in those patients with a known hypersensitivity to it or any of its ingredients or hydroxyzine. There is no information to indicate that abuse or dependency occurs with cetirizine hydrochloride.

CLINICAL PHARMACOLOGY
MECHANISM OF ACTIONS
Cetirizine, a human metabolite of hydroxyzine, is an antihistamine;
its principal effects
are mediated via selective inhibition of peripheral H
receptors. The antihistaminic activity
of cetirizine has been clearly documented in a variety of animal and
human models. _In_
_vivo_and _ex vivo_animal models have shown negligible anticholinergic
and antiserotonergic
activity. In clinical studies, however, dry mouth was more common with
cetirizine than
with placebo. _In vitro_receptor binding studies have shown no
measurable affinity for
other than H
receptors. Autoradiographic studies with radiolabeled cetirizine in
the rat
have shown negligible penetration into the brain. _Ex vivo_experiments
in the mouse have

shown that systemically administered cetirizine does not significantly
occupy cerebral H
receptors.
