What is Bonine and How It Works?
Bonine is a brand name for the medication meclizine hydrochloride, an over-the-counter (OTC) antiemetic used to prevent and treat symptoms of motion sickness. Motion sickness occurs when there is a mismatch between the sensory information received by your eyes, inner ears, and body, which can be triggered by movement in a car, boat, or airplane. This sensory conflict sends signals to the brain that can result in nausea, vomiting, and dizziness.
The Mechanism of Action: The Role of Meclizine
Meclizine works as a first-generation antihistamine and also has anticholinergic properties. The drug works primarily by blocking specific receptors in the brain that are involved in the vomiting reflex. By targeting these receptors, meclizine helps to dampen the signals sent from the inner ear's vestibular system, which is crucial for balance and spatial orientation, to the brain's vomiting center. This action effectively reduces the feelings of nausea and dizziness associated with motion sickness and vertigo. Meclizine takes about one hour to begin working and can provide effects that last for up to 24 hours.
Key Uses and Benefits
Bonine is primarily used for the prevention and treatment of motion sickness and vertigo. Its benefits include:
- Long-Lasting Relief: A single use can be effective for up to 24 hours, making it a convenient choice for travelers on cruises, road trips, and flights.
- Less Drowsiness: Bonine is often marketed as a "less drowsy" formula compared to other motion sickness medications containing dimenhydrinate, which allows for more alertness during travel.
- Relief for Vertigo: In addition to motion sickness, Bonine is also used to manage the symptoms of vertigo, including dizziness and a spinning sensation, that can be caused by diseases affecting the inner ear.
- Convenient Formulations: Bonine is available in chewable tablets that can be taken without water, which is ideal for on-the-go use.
Bonine vs. Dramamine: A Comparison
When choosing a motion sickness medication, many people compare Bonine and Dramamine. While both are effective antihistamines, there are key differences to consider.
| Feature | Bonine (Meclizine) | Dramamine Original (Dimenhydrinate) | Dramamine Less Drowsy (Meclizine) |
|---|---|---|---|
| Active Ingredient | Meclizine HCl | Dimenhydrinate | Meclizine HCl |
| Dosing Frequency | Typically once daily for 24-hour relief | Typically every 4 to 6 hours | Typically once daily for 24-hour relief |
| Onset of Action | About 1 hour | About 30 minutes | About 1 hour |
| Level of Drowsiness | Less drowsy | Can cause significant drowsiness | Less drowsy |
| Age Restriction | 12 years and older | 2 years and older | 12 years and older |
Administration Guidelines
For best results, Bonine should typically be taken one hour before travel or anticipated motion sickness symptoms. This allows the medication enough time to become effective. It can be taken with or without food. Adults and children 12 years and older should follow the instructions on the package or as directed by a healthcare professional.
How to Take Bonine
- Chewable Tablets: Ensure the chewable tablet is chewed completely before swallowing.
- Timing is Key: For prevention, taking the medication one hour before starting your journey is often recommended. This proactive approach is more effective than waiting for symptoms to appear.
- Following Instructions: Adhere to the specific dosing instructions provided on the packaging or by a healthcare professional, especially when treating conditions like vertigo.
Potential Side Effects and Precautions
Like all medications, Bonine can cause side effects, although they are generally mild. Common side effects include drowsiness, dry mouth, headache, and fatigue. To manage dry mouth, sucking on candy or drinking plenty of water can help. In older adults, long-term use is associated with risks such as delirium and falls.
Important Precautions
- Alcohol: Avoid drinking alcohol while taking Bonine, as it can increase drowsiness and other side effects.
- Operating Machinery: Bonine can impair your reactions and judgment. Do not drive or operate heavy machinery until you know how the medication affects you.
- Pre-existing Conditions: Individuals with certain health conditions should consult a doctor before taking Bonine. These include glaucoma, asthma, emphysema, chronic bronchitis, and an enlarged prostate.
- Drug Interactions: Bonine can interact with other medications that cause drowsiness, such as sedatives, tranquilizers, and certain pain relievers. Always consult a healthcare provider about potential interactions.
- Pregnancy and Breastfeeding: While considered a Category B drug, pregnant or breastfeeding individuals should consult a healthcare professional before use.

Conclusion
Bonine, with its active ingredient meclizine, offers a reliable and convenient solution for preventing and treating motion sickness and vertigo. Its once-daily, less-drowsy formula provides long-lasting relief, making it a popular choice for travelers. While generally safe, it is crucial to be aware of potential side effects, precautions, and interactions, especially for individuals with pre-existing health conditions or those taking other medications. Always read the product label and consult a healthcare provider to ensure it is the right option for your needs.
