These products are readily accessible and often marketed to support travellers and individuals prone to vertigo.
ATC Code and Classification
Meclizine falls under the Anatomical Therapeutic Chemical (ATC) classification code N07CA03. It is categorized as an antiemetic and antivertigo drug, specifically classifying it as a histamine H1 antagonist. This classification underscores its role in blocking histamine receptors in the brain, aimed at reducing symptoms of nausea and vertigo.
Manufacturers
Casper Pharma LLC stands out as one of the prominent manufacturers of Meclizine, selling products like Antivert®. Besides Casper, several international players produce generic versions and other branded alternatives, such as Teva and Sandoz, which are widely available through local pharmacies and online platforms.
Regulatory Status
In Canada, Meclizine is available both over-the-counter (OTC) and via prescription. Lower doses (typically under 25 mg) can be purchased without a doctor's note for treating motion sickness. However, higher doses are often reserved for more serious health conditions such as vestibular disorders and require a prescription. The regulatory landscape may differ internationally, as the FDA in the United States also permits certain forms of Meclizine as OTC, while other countries might mandate stricter prescription requirements. Checking local regulations ensures compliant and safe procurement.
Pharmacology of Meclizine
The effectiveness of Meclizine is attributed to its action on histamine H1 receptors in the central nervous system. By inhibiting these receptors, it helps alleviate feelings of nausea and prevents vomiting. This mechanism is particularly beneficial for individuals experiencing motion sickness or vertigo, providing rapid relief by calming the body’s response to such stimuli.
Onset, Metabolism, Elimination
Typically, Meclizine's onset of action occurs within one hour of administration, making it a suitable choice for preemptively dealing with motion sickness. Once ingested, it undergoes metabolism in the liver, with elimination primarily through urine. While specific timelines can vary by individual, the average duration of action lasts between 12 to 24 hours, allowing for once-daily dosing in many cases.
Interactions to Be Aware Of
It’s vital to consider significant interactions with Meclizine. Common interactions include:
- Antidepressants and antipsychotics, which can enhance sedative effects.
- Alcohol, which can lead to excessive drowsiness.
- Other medications that act on the central nervous system, as they may contribute to increased side effects.
Patients should consult healthcare providers when combining Meclizine with other medications to avoid potential risks and ensure safe usage.
Indications for Use
The primary approved uses for Antivert include treating motion sickness and managing symptoms associated with vertigo. These indications are recognized by regulatory bodies, including the FDA, which emphasize the efficacy of Meclizine in alleviating dizziness and nausea.
Off-Label Uses
In Canada, healthcare professionals may prescribe Meclizine off-label for conditions such as migraine-associated nausea or anxiety-related dizziness. While these uses may not be formally approved, they demonstrate the versatility of Meclizine in clinical settings.
Special Populations Considerations
When prescribing Meclizine, unique considerations arise for:
- Pediatrics: Generally, it is not recommended for children under 12 years.
- The Elderly: Extra caution is advised due to a higher risk of side effects such as sedation and confusion.
- Pregnant Women: Consultation with healthcare providers is essential to evaluate risks versus benefits.
Overall, understanding these considerations ensures Meclizine is used effectively and safely across various demographics.

Determining the right dosage of Meclizine is key to its effectiveness. Below are standard dosages based on conditions treated:
| Condition | Adult Dosage | Pediatric Dosage |
|---|---|---|
| Motion Sickness | 25–50 mg 1 hour before travel; may repeat every 24 hours as needed | Not recommended for children under 12 years |
| Vertigo | 25–100 mg daily, divided doses | Not recommended for children under 12 years |
Adjustments for Specific Populations
Dosage adjustments are essential for:
- The elderly, who often require the lowest effective dose
- Patients with renal or liver impairments, for whom monitoring is advised
Careful titration ensures safety and minimizes side effects.
Storage and Transport Guidelines
To maintain its effectiveness, Meclizine should be stored at room temperature, ideally between 20–25°C, and protected from moisture and heat. When transporting, keeping it in its original packaging is recommended to avoid degradation. Taking these precautions ensures the medication remains potent when needed.
⚠️ Safety & Warnings
When considering Antivert, it is crucial to understand its contraindications, side effects, and precautions. Absolute contraindications include known hypersensitivity to meclizine or any of its components, and its use is not recommended in children under twelve years of age unless directed by a healthcare provider. Caution should be exercised in individuals with:
- Glaucoma
- Urinary retention or prostatic hypertrophy
- Respiratory disorders like asthma
- Liver or kidney impairment
- Older adults, due to increased risk of falls and cognitive effects
Common side effects can range from mild to severe. Mild effects may include drowsiness, dry mouth, headaches, and blurred vision. Moderate side effects can escalate to sedation, confusion—especially notable in older patients—and urinary retention. Special precautions are necessary for pregnant women; while limited studies exist, consulting with a healthcare provider prior to use is essential. Patients with liver or kidney impairments need tailored dosages; monitoring for CNS effects is advisable. Notably, there are no black box warnings associated with Antivert, indicating a relatively safe profile when used as directed.
🗣️ Patient Experience
User reviews from platforms like Drugs.com and WebMD highlight a generally positive feedback loop regarding Antivert's effectiveness, especially for motion sickness and vertigo relief. Many users appreciate its rapid onset and effectiveness in reducing nausea. However, some have pointed out side effects such as drowsiness and dry mouth, which prompted them to adjust activities, like avoiding driving until familiar with how the medication affects them. Overall, patients feel more at ease when they understand both its benefits and potential downsides, allowing for informed usage while minimizing anxiety around side effects.
⚖️ Alternatives & Comparison
In Canada, several alternative medications can be considered for conditions treated by Antivert. Dimenhydrinate (Dramamine) is commonly used for motion sickness, and while it might be more sedating, it offers similar benefits. Cyclizine serves as another alternative, focusing on vertigo and nausea but carrying its own side effect profile. Promethazine is frequently prescribed for its anti-nausea effects but is not primarily an antihistamine like meclizine.
