Uses and warnings
No boxed warning. Hydroxyzine is contraindicated in patients with known hypersensitivity to hydroxyzine or to cetirizine/levocetirizine, in patients with "a prolonged QT interval," and is "contraindicated in early pregnancy"; it should not be given to nursing mothers. The label warns that hydroxyzine "has been associated with QT interval prolongation and Torsade de Pointes," a risk increased by concomitant use of other QT-prolonging drugs, and that it potentiates the CNS-depressant effects of narcotics, non-narcotic analgesics, barbiturates, and other CNS depressants.
Hydroxyzine Hydrochloride Tablets are indicated for: - Symptomatic relief of "anxiety and tension associated with psychoneurosis" and as adjunctive therapy in organic disease states where anxiety is a component - "Management of pruritus due to allergic conditions such as chronic urticaria and atopic and contact dermatoses" - As a sedative when used as a premedicant and following general anesthesia
