Distribution
Drug distribution characteristics for Meclizine Hydrochloride, USP in humans remains unknown.
Metabolism
The metabolic fate of Meclizine Hydrochloride, USP in humans is unknown. In an in vitro metabolic study using human hepatic microsome and recombinant CYP enzyme, CYP 2D6 was found to be the dominant enzyme for metabolism of Meclizine Hydrochloride, USP.
The genetic polymorphism of CYP2D6 that results in extensive-, poor-, intermediate- and ultrarapid metabolizer phenotypes could contribute to large inter-individual variability in Meclizine Hydrochloride, USP exposure.
Elimination
Meclizine Hydrochloride, USP has a plasma elimination half-life of about 5-6 hours in humans.

Ask a doctor before use if you are taking sedatives or tranquilizers.
When using this product: 1. Do not exceed the recommended dosage. 2. May cause drowsiness. 3. Patients should avoid alcoholic beverages while taking this drug. 4. 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. Therefore patients are reminded caution when driving or operating machinery. 5. Alcohol, sedatives and tranquilizers may increase drowsiness.
If pregnant or breast-feeding, ask a health professional before use.

Precautions
Pediatric Use
Clinical studies establishing safety and effectiveness in children under 12 years of age have not been done; therefore, usage is not recommended in children under 12 years of age unless directed by a doctor.
Pregnancy Use
Pregnancy Category B. Reproduction studies in rats have shown cleft palates at 25 to 50 times the human dose. Epidemiological studies in pregnant women, however, do not indicate that Meclizine Hydrochloride, USP increases the risk of abnormalities when administered during pregnancy. Despite the animal findings, it would appear that the possibility of fetal harm is remote. Nevertheless, Meclizine Hydrochloride, USP or any other medication, should be used during pregnancy only if clearly necessary, and after speaking with a health professional.
Nursing Mothers

Hepatic Impairment
The effect of hepatic impairment on the pharmacokinetics of meclizine has not been evaluated. As Meclizine Hydrochloride, USP undergoes metabolism, hepatic impairment may result in increased systemic exposure of the drug. Treatment with Meclizine Hydrochloride, USP should be administered with caution in patients with hepatic impairment.
Renal Impairment
The effect of renal impairment on the pharmacokinetics of Meclizine Hydrochloride, USP has not been evaluated. Due to a potential for drug/metabolite accumulation, Meclizine Hydrochloride, USP should be administered with caution in patients with renal impairment and in the elderly as renal function generally declines with age.
Drug Interactions
There may be increased CNS depression when Meclizine Hydrochloride, USP is administered concurrently with other CNS depressants, including alcohol, tranquilizers and sedatives. (see WARNINGS)
Based on in vitro evaluation, Meclizine Hydrochloride, USP is metabolized by CYP2D6. Therefore there is a possibility for a drug interaction between Meclizine Hydrochloride, USP and CYP2D6 inhibitors.
