In addition, each tablet contains the following inactive ingredients: colloidal silicon dioxide, corn starch, D&C yellow # 10 lake (25 mg only), FD&C blue # 1 lake (12.5 mg only), lactose monohydrate, microcrystalline cellulose, povidone (12.5 mg only), sodium starch glycolate, and stearic acid.Close
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. It has a slower onset and longer duration of action (24 hours) than most other antihistamines used for motion sickness.
Antihistamines have been observed to have both stimulant and depressant effects on the CNS, but no clear explanation exists in regard to their diverse central actions. The site and mode of their central action is unknown.Close
Prophylactic treatment and management of nausea and vomiting, and dizziness associated with motion sickness.Close
Meclizine HCl is contraindicated in individuals who have shown a previous hypersensitivity to it.Close
Some drowsiness may, on occasion, occur with the 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.Close
- USAGE IN PEDIATRIC PATIENTS
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.Close
- USAGE IN PREGNANCY
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.Close
- ADVERSE REACTIONS
Drowsiness, dry mouth, and on rare occasions, blurred vision have been reported.Close
- DOSAGE AND ADMINISTRATION
Motion Sickness: The initial dose of 25 to 50 mg of meclizine, should be taken prior to travel for protection against motion sickness. Thereafter, the dose may be repeated every 24 hours for the duration of the journey.Close
