Common use

Antivert is primarily indicated for the management of vertigo associated with diseases affecting the vestibular system, such as Ménière’s disease, labyrinthitis, and vestibular neuronitis. It is also widely used for the prevention and treatment of nausea, vomiting, and dizziness caused by motion sickness during air, sea, or car travel. Off-label, it is sometimes utilized to alleviate nausea in pregnancy (under strict medical supervision) and as an adjunct in managing symptoms related to certain types of migraines or inner ear disorders.

Dosage and direction

For vertigo: The typical adult dosage is 25–100 mg daily, divided into doses as directed by a physician, often starting with 25 mg taken at bedtime. For motion sickness: The recommended dose is 25–50 mg taken one hour before travel, repeated every 24 hours for the duration of the journey. Dosage may be adjusted based on severity of symptoms, patient response, and tolerability. Tablets should be swallowed whole with water, with or without food. Do not crush or chew. Always follow the specific instructions provided by your healthcare provider.

Precautions

• Use with caution in patients with glaucoma, prostate enlargement, or respiratory conditions such as asthma
• May cause drowsiness; avoid driving or operating machinery until effects are known
• Alcohol and other CNS depressants can enhance drowsiness and should be avoided
• Not recommended for children under 12 years of age unless directed by a pediatrician
• Elderly patients may be more sensitive to side effects and often require lower doses
• Inform your doctor if you are pregnant, planning pregnancy, or breastfeeding

Contraindications

Antivert is contraindicated in individuals with a known hypersensitivity to meclizine or any component of the formulation. It should not be used in patients with narrow-angle glaucoma or urinary retention due to its anticholinergic properties. Avoid use in patients with severe liver impairment. Concomitant use with monoamine oxidase inhibitors (MAOIs) is contraindicated due to the risk of exaggerated anticholinergic effects.

Possible side effects

Common side effects may include drowsiness, dry mouth, blurred vision, and headache. These are generally mild and often diminish with continued use. Less frequently, patients may experience fatigue, vomiting, or nervousness. Rare but serious side effects include difficulty urinating, palpitations, rash, or signs of an allergic reaction such as swelling or difficulty breathing. Report any persistent or severe side effects to your healthcare provider promptly.

Drug interaction

Antivert may interact with other CNS depressants including alcohol, benzodiazepines, opioids, and sleep aids, potentially increasing sedation. Concurrent use with anticholinergic agents (e.g., atropine, tricyclic antidepressants) may enhance dry mouth, constipation, or blurred vision. It may also interact with MAO inhibitors, leading to heightened side effects. Always inform your doctor of all medications, supplements, and herbal products you are taking.

Missed dose

If you miss a dose of Antivert, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and resume your regular dosing schedule. Do not double the dose to make up for a missed one. For motion sickness use, take the missed dose as soon as possible unless your next scheduled dose is within a few hours.

Overdose

Symptoms of overdose may include extreme drowsiness, confusion, agitation, hallucinations, seizures, or coma. In case of suspected overdose, seek emergency medical attention immediately. Treatment is supportive and may include activated charcoal, monitoring of vital signs, and symptomatic care. Do not induce vomiting unless directed by medical personnel.

Storage

Store Antivert at room temperature (15–30°C or 59–86°F) in a tightly closed container, away from light, moisture, and heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Dispose of unused medication through a pharmacy take-back program or as advised by your local guidelines.
