C25H27ClN2• 2HCl • H2O                              M.W. 481.89

Each tablet for oral administration contains 12.5 mg or 25 mg meclizine hydrochloride. Inactive ingredients include: croscarmellose sodium, hydroxypropyl methylcellulose, lactose (monohydrate), magnesium stearate, microcrystalline cellulose, polysorbate 80. The 12.5 mg also contains FD & C Blue #1 Aluminum Lake; the 25 mg also contains D & C Yellow #10 Aluminum Lake and FD & C Yellow #6 Aluminum Lake.

CLINICAL PHARMACOLOGY

Meclizine HCl 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.

INDICATIONS AND USAGE

For the prevention and treatment of nausea, vomiting or dizziness associated with motion sickness.

CONTRAINDICATIONS

Meclizine HCl is contraindicated in individuals who have shown a previous hypersensitivity to it.

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 this 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

Pregnancy, Teratogenic Effects, Pregnancy Category B

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 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, or any other medication, should be used during pregnancy only if clearly necessary.

Pediatric Use

Clinical studies establishing safety and effectiveness in pediatric patients have not been done; therefore, usage is not recommended in pediatric patients under 12 years of age.

ADVERSE REACTIONS

Drowsiness, dry mouth and, on rare occasions, blurred vision have been reported.

DOSAGE AND ADMINISTRATION

Motion Sickness

The initial dose of 25 to 50 mg of meclizine HCl should be taken one hour prior to travel for protection against motion sickness. Thereafter, the dose may be repeated every 24 hours for the duration of the journey.
