  • CLINICAL PHARMACOLOGY

    Meclizine hydrochloride is an antihistamine which shows marked protective activity against nebulized histamine and lethal doses of intravenously injected histamine in guinea pigs. It has a marked effect in blocking the vasodepressor response to histamine, but only a slight blocking action against acetylcholine. Its activity is relatively weak in inhibiting the spasmogenic action of histamine on isolated guinea pig ileum.

  • WARNINGS

    Since drowsiness may, on occasion, occur with use of this drug, patients should be warned of this possibility and cautioned against driving a car or operating dangerous machinery.

    Patients should avoid alcoholic beverages while taking the drug. Due to its potential anticholinergic action, this drug should be used with caution in patients with asthma, glaucoma, or enlargement of the prostate gland. Do not give to children under 12 years of age unless directed by a doctor.

  • PRECAUTIONS

    The Meclizine Hydrochloride Tablets, 25 mg contain FD&C Yellow #5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible individuals. Although the overall incidence of FD&C Yellow #5 (tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity.

    Clinical studies establishing safety and effectiveness in children have not been done; therefore, usage is not recommended under 12 years of age. Usage in Children:

    Reproduction studies in rats have shown cleft palates at 25-50 times the human dose. Epidemiological studies in pregnant women, however, do not indicate that meclizine hydrochloride increases the risk of abnormalities when administered during pregnancy. Usage in Pregnancy:Pregnancy Category B.

    Despite the animal findings, it would appear that the possibility of fetal harm is remote. Nevertheless, meclizine hydrochloride, or any other medication should be used during pregnancy only if clearly necessary.
