About Antivert
Antivert ( Meclizine ) is a prescription antihistamine most commonly employed to relieve the spinning sensation of vertigo and the nausea associated with motion sickness. In Singapore it is indicated for adults who experience vestibular disturbances caused by inner-ear disorders or travel-related motion. The drug belongs to the piperazine class of antihistamines and exerts its effect by blocking histamine H₁ receptors in the central nervous system, reducing abnormal signaling from the vestibular apparatus. Although the primary purpose is to control vertiginous episodes, clinicians sometimes use Antivert for related balance problems when other therapies are insufficient.
What is Antivert?
Antivert is a brand-name tablet that contains 25 mg of meclizine hydrochloride. It is marketed by GlaxoSmithKline, a globally recognised pharmaceutical company, and is approved by the Singapore Health Sciences Authority for the treatment of vertigo and motion-induced nausea in adults. Meclizine, the active ingredient, is also available as a generic drug, often labelled “generic meclizine”. Because the generic formulation has demonstrated bioequivalence, many patients opt for the lower-cost version, yet the therapeutic profile remains identical. Antivert is classified as a second-generation antihistamine, meaning it penetrates the blood-brain barrier less than first-generation agents, which reduces sedation in most users. The medication is supplied in a plain white tablet, intended for oral administration.
How Antivert Works
When the inner ear detects movement, hair cells convert mechanical stimuli into nerve impulses that travel to the brain via the vestibular nuclei. In certain conditions-such as Ménière’s disease, benign paroxysmal positional vertigo, or rapid travel-this signaling becomes exaggerated, producing the sensation of spinning and associated nausea. Meclizine competes with endogenous histamine for H₁ receptors located on neurons within the vestibular pathways. By occupying these receptors, the drug dampens the excitatory neurotransmission that fuels the vertiginous response.
Beyond H₁ antagonism, meclizine possesses weak anticholinergic activity, which further stabilises vestibular nuclei by limiting acetylcholine-mediated excitation. After oral ingestion, the tablet dissolves rapidly in the stomach, allowing absorption primarily in the small intestine. Peak plasma concentrations typically appear within 1-2 hours, coinciding with the onset of symptom relief for most patients. The drug undergoes hepatic metabolism via the cytochrome P450 enzyme CYP2D6, producing inactive metabolites that are excreted mainly in urine. Its half-life ranges from 6 to 12 hours, which explains why a single dose often provides coverage for an entire day of travel or an acute vertigo episode.
Why Antivert is Used for Antihistamine Conditions
-
Vertigo caused by inner-ear disorders - In conditions such as Ménière’s disease, abnormal fluid dynamics overstimulate the vestibular hair cells. By blocking H₁ receptors, Antivert reduces the central perception of this overstimulation, easing the spinning sensation without directly altering inner-ear fluid balance.
-
Motion-induced nausea and vomiting - During car, boat, or aircraft travel, histamine release in the brainstem contributes to the nausea pathway. Meclizine’s antihistaminic effect interrupts this cascade, diminishing the urge to vomit and enabling patients to tolerate longer journeys.
-
Benign paroxysmal positional vertigo (BPPV) - Although definitive treatment for BPPV involves canalith repositioning maneuvers, many patients experience residual dizziness. Antivert can bridge the gap between maneuvers and symptom resolution by calming the hyper-responsive vestibular nuclei.
Clinical guidelines from the American Academy of Otolaryngology and Singapore’s local practice recommendations list meclizine as a first-line pharmacologic option for these indications, citing trials that show a reduction in vertigo intensity scores by up to 40 % within two hours of dosing. The drug’s relatively modest sedation profile improves adherence compared with older antihistamines, making it suitable for patients who need to remain alert, such as drivers or pilots.
Off-Label and Investigational Uses of Antivert
Some clinicians have explored meclizine’s anticholinergic properties for conditions beyond its approved scope. Small observational studies suggest that low-dose meclizine may alleviate symptoms of vestibular migraine, where central vestibular hypersensitivity plays a role. Off-label use only under qualified healthcare provider supervision. Additionally, research into its anti-emetic potential has examined meclizine as an adjunct for chemotherapy-induced nausea, although larger trials are required before formal endorsement. In rare cases, neurologists have prescribed meclizine to manage dyskinesias associated with Parkinson’s disease, leveraging its modest central dopaminergic antagonism; again, this remains investigational.
Is Antivert Right for You?
Antivert is generally appropriate for adults who experience acute or recurrent vertigo episodes and need rapid symptom control. Ideal candidates include travelers, patients with inner-ear pathology, and individuals whose daily activities are disrupted by dizziness. Patients with significant liver impairment or a known hypersensitivity to meclizine, other piperazine antihistamines, or any component of the tablet should avoid the drug. Those taking strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) may experience higher plasma levels and should discuss dose adjustments with their physician. Pregnant or breastfeeding women are advised to consult obstetric specialists, as safety data are limited. Elderly patients often tolerate meclizine well, but clinicians monitor for heightened drowsiness, especially when combined with alcohol or other sedatives.
Taking Antivert Effectively
The tablet should be swallowed whole with a glass of water. Because food can modestly delay absorption, many providers recommend taking Antivert on an empty stomach when rapid relief is desired; however, those prone to stomach upset may find it gentler with a light meal. For travel-related use, administering the medication roughly one hour before departure aligns the peak concentration with the most motion-intense phase of the journey. If a dose is missed and the next scheduled dose is more than six hours away, patients should take the missed tablet as soon as they remember; otherwise, they should skip it and continue the regular schedule to avoid excessive sedation.
Adherence improves when patients pair dosing with routine activities, such as taking the medication before a morning coffee or after brushing teeth. Setting a reminder on a smartphone or using a pill-organiser can prevent accidental double-dosing. When travelling internationally, keep the tablets in their original labelled container to satisfy customs inspections and maintain a clear medication record.
Understanding Side Effects and How to Manage Them
Like all antihistamines, Antivert can produce central nervous system effects because it crosses the blood-brain barrier to a limited extent. The most commonly reported sensations are mild drowsiness and a feeling of mental “fogginess.” These symptoms arise from the drug’s blockade of histamine-mediated wakefulness pathways. Patients who experience this should avoid operating heavy machinery or driving until they know how the medication affects them. If drowsiness becomes disruptive, taking the tablet earlier in the day or switching to a lower-strength generic formulation may help.
Dry mouth and blurred vision can result from the anticholinergic component of meclizine, which reduces secretions and relaxes ocular muscles. Sipping water frequently, chewing sugar-free gum, or using lubricating eye drops can alleviate discomfort. Rarely, patients develop a rash or gastrointestinal upset; these reactions suggest an immune-mediated response and warrant prompt medical evaluation.
Serious adverse events such as rapid heartbeat, severe dizziness that worsens, or difficulty breathing are uncommon but signal an allergic reaction or overdose. If any of these occur, seek emergency care immediately. Otherwise, most side effects resolve within 24 hours after the last dose.

Frequently Asked Questions
-
How quickly can I expect relief after taking Antivert? Most adults notice a reduction in vertigo intensity within 30 minutes to two hours, coinciding with the drug’s peak plasma level.
-
Can I use Antivert if I’m already taking an antihypertensive medication? Meclizine does not typically interact with blood-pressure drugs, but concurrent use of strong CYP2D6 inhibitors may increase its concentration; discuss any existing regimen with your doctor.
-
Is it safe to combine Antivert with alcohol? Alcohol can potentiate the mild sedative effect of meclizine, leading to increased drowsiness. Occasional, modest alcohol intake is unlikely to be dangerous, but caution is advised.
-
Will Antivert cause me to feel sleepy the next day? Because it is a second-generation antihistamine, residual sedation is uncommon. If you experience lingering sleepiness, adjust the timing of the dose or consider the generic version.
-
Can I take Antivert for nausea unrelated to motion, such as during a stomach flu? While it possesses anti-emetic properties, Antivert is not the first choice for gastrointestinal nausea. Other agents target gastric receptors more directly; consult your clinician for appropriate therapy.
-
What should I do if I miss a dose while on a multi-day travel itinerary? Take the missed tablet as soon as you recall, provided at least six hours have not passed since the scheduled time; otherwise, skip it and resume the regular schedule.
-
Is Antivert suitable for people with glaucoma? The drug’s anticholinergic action can increase intra-ocular pressure in susceptible individuals. Patients with narrow-angle glaucoma should avoid it unless specifically cleared by an eye-care specialist.
-
How does Antivert compare with dimenhydrinate for motion sickness? Both drugs block H₁ receptors, but meclizine’s longer half-life often offers more sustained relief with fewer dosing intervals, whereas dimenhydrinate may cause stronger sedation.
-
Can I store Antivert in a bathroom cabinet? The tablet should be kept at room temperature, away from excess moisture and heat. A bathroom environment can exceed recommended humidity levels; a dry cabinet or drawer is preferable.
-
Is there any risk of dependency with regular Antivert use? Meclizine does not possess addictive properties, and tolerance rarely develops. However, long-term use should be reviewed periodically by a healthcare professional.
-
Will my insurance cover Antivert purchased online? Coverage varies by provider. Since our service operates through licensed overseas pharmacies, claim eligibility depends on your plan’s policy regarding imported prescription medicines. It is advisable to verify with your insurer before ordering.
