  • 4 CONTRAINDICATIONS

    ANTIVERT® is contraindicated in patients with a hypersensitivity to meclizine or any of the inactive ingredients [see Adverse Reactions (6) and Description (11)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Drowsiness

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

    Patients should avoid alcoholic beverages while taking ANTIVERT®[see Drug Interactions (7.1)].

    5.2 Concurrent Medical Conditions

    Because of its potential anticholinergic action, ANTIVERT® should be used with caution in patients with asthma, glaucoma, or enlargement of the prostate gland.

  • 6 ADVERSE REACTIONS

    The following adverse reactions associated with the use of ANTIVERT® were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    Anaphylactic reaction, drowsiness, dry mouth, headache, fatigue, and vomiting. On rare occasions blurred vision has been reported.

  • 7 DRUG INTERACTIONS

    7.1 CNS Depressants

    There may be increased CNS depression when ANTIVERT® is administered concurrently with other CNS depressants, including alcohol [see Warnings and Precautions (5.1)].

    7.2 CYP2D6 Inhibitors

    Based on in-vitro evaluation, meclizine is metabolized by CYP2D6. Therefore, there is a possibility for a drug interaction between ANTIVERT® and CYP2D6 inhibitors. Therefore, monitor for adverse reactions and clinical effect accordingly.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary
    Data from epidemiological studies have not generally indicated a drug-associated risk of major birth defects with meclizine during pregnancy. However, in a published study, an increased incidence of fetal malformations was observed following oral administration of meclizine to pregnant rats during the period of organogenesis, at doses similar to those used clinically.

    In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.

    Data
    Human Data
    Epidemiological studies reporting on pregnancies exposed to meclizine have not identified an association between the use of meclizine during pregnancy and an increased risk of major birth defects.

    Animal Data
    In a published study, oral administration of meclizine (25-250 mg/kg) to pregnant rats during the period of organogenesis resulted in a high incidence of fetal malformations. These effects occurred at doses as low as 25 mg/kg, which is approximately 2 times the maximum recommended human dose (100 mg) on a body surface area (mg/m2) basis.

    8.2 Lactation

    Risk Summary
    There are no data on the presence of meclizine in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ANTIVERT® and any potential adverse effects on the breastfed infant from ANTIVERT® or from the underlying maternal condition.

    8.4 Pediatric Use

    Safety and effectiveness in pediatric patients have not been established.

    8.5 Geriatric Use

    In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

    8.6 Hepatic Impairment

    The effect of hepatic impairment on the pharmacokinetics of meclizine has not been evaluated. As ANTIVERT® undergoes metabolism, hepatic impairment may result in increased systemic exposure of meclizine. Treatment with ANTIVERT® should be administered with caution in patients with hepatic impairment.

    8.7 Renal Impairment

    The effect of renal impairment on the pharmacokinetics of meclizine has not been evaluated. Because of a potential for drug/metabolite accumulation, ANTIVERT® should be administered with caution in patients with renal impairment and in the elderly, as renal function generally declines with age.

    8.8 Genetic CYP2D6 Polymorphism

    The genetic polymorphism of CYP2D6 that results in poor-, intermediate-, extensive-, and ultrarapid metabolizer phenotypes could contribute to large inter-individual variability in meclizine exposure. Therefore, when ANTIVERT® is administered to patients with CYP2D6 polymorphism, monitor for adverse reactions and clinical effect accordingly.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The precise mechanism by which meclizine exerts its therapeutic effect is unknown but is presumed to involve antagonism of the histamine H1 receptor.

    12.2 Pharmacodynamics

    There are no relevant pharmacodynamic data regarding meclizine.

    12.3 Pharmacokinetics

    The available pharmacokinetic information for meclizine following oral administration has been summarized from published literature.

    Absorption
    Meclizine is absorbed after oral administration with maximum plasma concentrations reaching at a median Tmax value of 3 hours post-dose (range: 1.5 to 6 hours) for the tablet dosage form.

    Distribution
    Drug distribution characteristics for meclizine in humans are unknown.

    Elimination
    Meclizine has a plasma elimination half-life of about 5-6 hours in humans.

    Metabolism
    In an in vitro metabolic study using human hepatic microsome and recombinant CYP enzyme, CYP2D6 was found to be the dominant enzyme for metabolism of meclizine.
