Generic Antivert Information

Introduction

Antivert is a prescription medication containing the antihistamine Meclizine. It belongs to the motion‑sickness drug group and is primarily used to prevent and treat vertigo, dizziness, and nausea associated with inner‑ear disturbances. In Hong Kong, Antivert is licensed by the Department of Health and is commonly prescribed for travelers, patients with vestibular disorders, and those undergoing chemotherapy‑induced nausea. Its rapid onset and relatively long duration of action make it a convenient option for adults who need reliable control of vestibular symptoms.

What is Antivert?

Antivert is a brand‑name formulation of Meclizine hydrochloride. Meclizine is a piperazine‑derived antihistamine that exerts its therapeutic effect by blocking H₁ receptors in the vestibular nuclei and the vomiting center of the brain. The product is manufactured by several licensed pharmaceutical companies that hold a Good Manufacturing Practice (GMP) certification for distribution in Hong Kong. Antivert is available in tablet form (typically 25 mg) and is prescribed for oral administration.

How Antivert Works

Meclizine, the active ingredient of Antivert, antagonizes histamine H₁ receptors, which are involved in the transmission of vestibular signals that trigger motion‑sickness and vertigo. By blocking these receptors, Meclizine reduces the excitability of the vestibular apparatus and the central chemoreceptor trigger zone that initiates nausea and vomiting.

• Onset of action: symptoms are usually alleviated within 30 minutes after oral intake.
• Duration: therapeutic effects last 8–12 hours, allowing once‑daily dosing for many indications.
• Clearance: Meclizine is metabolized in the liver (CYP2D6 pathway) and excreted primarily via the kidneys; the mean plasma half‑life is approximately 6 hours in healthy adults.

These pharmacokinetic properties support its use as both a preventive and a treatment agent for vestibular disturbances.

Conditions Treated with Antivert

• Benign paroxysmal positional vertigo (BPPV) – a common cause of episodic dizziness in adults; Meclizine reduces the severity of vertiginous episodes.
• Menière’s disease – chronic inner‑ear disorder causing fluctuating vertigo; Antivert can lessen acute attacks.
• Travel‑induced motion sickness – nausea and vomiting caused by sea, air, or land travel; a single dose taken before exposure is effective.
• Chemotherapy‑induced nausea and vomiting (CINV) – Meclizine is sometimes used as an adjunct to anti‑emetic regimens in Hong Kong oncology practice.

Epidemiologically, vestibular disorders affect an estimated 5 % of Hong Kong’s adult population, with higher prevalence among older adults and individuals with occupational exposure to vibration. Motion‑sickness remains a frequent complaint among tourists and ferry commuters, underlining the public health relevance of Antivert.

Patient Groups Most Likely to Benefit

• Adults aged 18 – 65 with intermittent vertigo or motion‑sickness; the drug’s safety profile is well‑characterized in this range.
• Elderly patients (≥ 65 years) who experience BPPV; low‑dose regimens (12.5 mg) are often sufficient and reduce sedation risk.
• Patients undergoing chemotherapy where standard anti‑emetics are insufficient; Meclizine offers an additional mechanism of control.
• Travelers and maritime workers who require prophylactic treatment before exposure to motion stimuli.

Contra‑indications include known hypersensitivity to Meclizine, severe hepatic impairment, and concomitant use of potent central nervous system depressants (e.g., high‑dose benzodiazepines) that may amplify drowsiness.

Risks, Side Effects, and Interactions

Common

• Drowsiness or mild sedation (reported in ≈ 30 % of users)
• Dry mouth
• Blurred vision (especially in low‑light conditions)
• Mild gastrointestinal discomfort (nausea or constipation)

Rare

• Paradoxical excitation (restlessness, insomnia) in susceptible individuals
• Elevated liver enzymes (transient ALT/AST rise) observed in isolated case reports

Serious

• Severe allergic reactions (angio‑edema, urticaria, anaphylaxis) – immediate medical attention required
• Cardiac arrhythmias in patients with pre‑existing conduction disorders when combined with other QT‑prolonging agents
• Extrapyramidal symptoms (rare, primarily when combined with antipsychotics)

Drug–drug interactions

• Alcohol – synergistic CNS depression; patients should limit intake.
• Sedative antihistamines (e.g., diphenhydramine) – additive drowsiness.
• CYP2D6 inhibitors (e.g., fluoxetine, quinidine) – may increase Meclizine plasma levels, raising the risk of sedation and cardiac effects.
• Anticholinergic agents – may exacerbate dry‑mouth and blurred‑vision side effects.

Patients should disclose all concurrent medications, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for motion‑sickness prophylaxis: 25 mg taken 1 hour before travel; may repeat every 24 hours if exposure continues.
• For vertigo treatment: 25 mg once daily; in elderly or renal‑impaired patients, a reduced dose of 12.5 mg may be used.
• Missed dose – If a dose is forgotten and travel or symptom onset is still ≥ 2 hours away, take the missed dose; otherwise, skip and resume the regular schedule. Do not double the dose.
• Overdose – Symptoms may include profound sedation, hypotension, or cardiac arrhythmia. Immediate medical evaluation is advised; supportive care and monitoring are the standard interventions.
• Food and alcohol – Antivert may be taken with or without food; high‑fat meals can delay absorption slightly. Alcohol should be minimized due to additive CNS depressant effects.
• Comorbidities – Adjust dose in severe hepatic or renal impairment; consult a pharmacist for individualized recommendations.
