Treatment	Should overdose occur, treatment should be symptomatic or supportive, taking into account any concomitantly ingested medications. There is no known specific antidote to Cetirizine. (L1712)
Gesundheitliche Auswirkungen	Overdosage has been reported with ZYRTEC (cetirizine) . In one adult patient who took 150 mg of ZYRTEC (cetirizine) , the patient was somnolent but did not display any other clinical signs or abnormal blood chemistry or hematology results. In an 18 month old pediatric patient who took an overdose of ZYRTEC (cetirizine) (approximately 180 mg), restlessness and irritability were observed initiallythis was followed by drowsiness. (L1712)
Expositionspfade	Oralmean peak plasma concentration (Cmax) of 114 ng/mL at a time (Tmax) of 2.2 hours postdose was observed for cetirizine.
Toxizitätsübersicht	Cetirizine competes with histamine for binding at H<sub>1</sub>-receptor sites on the effector cell surface, resulting in suppression of histaminic edema, flare, and pruritus. The low incidence of sedation can be attributed to reduced penetration of cetirizine into the CNS as a result of the less lipophilic carboxyl group on the ethylamine side chain.

Anwendungen & Verwendung

Beschreibung

Cetirizine hydrochloride is a once-daily, non-sedating antihistamine useful in the treatment of allergic rhinitis, urticaria and conjunctivitis. It is reported to be more effective than most other agents in this category such as terfenadine and astemizole.

Verwenden

Cetirizine hydrochloride is a nonsedating type histamine H1-receptor antagonist. A major metabolite of Hydroxyzine. Pharmacological activity resides primarily in the (R)-isomer. It is Cetirizine is an antihistamine medicine that is effective in the treatment of allergic rhinitis, chronic urticaria, and pollen-induced asthma. Unlike many traditional antihistamines, it does not cause drowsiness or anticholinergic side effects.
