Quick Answer: Bonine (meclizine) is the better choice for most people. It causes significantly less drowsiness, lasts up to 24 hours per dose, and is equally effective at preventing motion sickness. Dramamine Original (dimenhydrinate) works slightly faster but causes heavy drowsiness and requires dosing every 4–6 hours. Fun fact: "Dramamine Less Drowsy" actually contains meclizine—the same active ingredient as Bonine.
Whether you're preparing for a cruise, dreading a winding mountain road, or trying not to get sick on your next flight, motion sickness medication can be a lifesaver. Dramamine and Bonine are the two biggest names in the category—but they work differently, and one might be significantly better for your situation.
Here's everything you need to know to choose the right one.

How Motion Sickness Medicines Work
Motion sickness occurs when your brain receives conflicting signals from your eyes, inner ear (vestibular system), and body position sensors. Your inner ear detects movement, but your eyes may see a stationary environment (like a car cabin or ship interior). This sensory mismatch triggers nausea, dizziness, and vomiting.
Dimenhydrinate (Dramamine Original)
Dimenhydrinate is actually a combination molecule: it's diphenhydramine (the active ingredient in Benadryl) bonded with 8-chlorotheophylline (a mild caffeine-like stimulant). The diphenhydramine component blocks H1 histamine receptors and muscarinic acetylcholine receptors in the vomiting center of the brain and the vestibular system. The theophylline is meant to partially offset drowsiness—but in practice, Dramamine is still very sedating.
Meclizine (Bonine)
Meclizine is also a first-generation antihistamine, but it's more selective for the vestibular system. It blocks H1 histamine receptors and has anticholinergic effects in the vomiting center, but it crosses the blood-brain barrier less aggressively than diphenhydramine. This is why it's classified as "less drowsy"—it targets motion sickness pathways while causing less sedation.
Did you know? "Dramamine Less Drowsy" and "Dramamine All Day Less Drowsy" actually contain meclizine 25 mg—the exact same active ingredient and dose as Bonine. The Dramamine brand name is used, but pharmacologically they are identical products.
Effectiveness: How Do They Compare?
Both dimenhydrinate and meclizine have been used for decades to prevent and treat motion sickness. Clinical evidence shows they are roughly equivalent in effectiveness for preventing motion sickness symptoms. Key findings:
- Prevention vs. treatment: Both medications work much better when taken BEFORE motion exposure. Once nausea has started, effectiveness drops significantly
- Cruise studies: Meclizine is the most commonly recommended OTC motion sickness medication for cruises because of its once-daily dosing and lower sedation
- Military and aviation research: Both medications are studied extensively; meclizine is preferred in settings where alertness matters
- Duration advantage: Bonine's 24-hour duration means consistent protection without redosing—important for cruises and long travel days
When Dramamine Might Work Better
Some individuals with severe motion sickness report that Dramamine Original works better for them, possibly because the deeper sedation itself helps reduce the nausea response. If you can afford to be drowsy (as a passenger, not a driver) and have severe symptoms, Dramamine's stronger anticholinergic effects may provide more relief. It also kicks in about 10–15 minutes faster than meclizine.
Side Effects Comparison
| Side Effect | Dramamine Original | Bonine |
|---|---|---|
| Drowsiness | Very common, often severe | Mild to moderate |
| Dry mouth | Very common | Common |
| Blurred vision | Common | Less common |
| Urinary retention | Possible | Less likely |
| Constipation | Possible | Possible |
| Dizziness | Common | Less common |
| Impaired driving | Yes—do NOT drive | Use caution |
Drowsiness Warning: Dramamine Original causes drowsiness comparable to Benadryl. Do NOT drive, operate machinery, or consume alcohol while taking it. Bonine is less sedating but can still impair alertness in some individuals. Test your reaction before any activity requiring full concentration.
Drug Interactions and Precautions
Both Dramamine and Bonine are first-generation antihistamines with anticholinergic properties. They share similar interaction profiles:
Interactions to Watch
- Alcohol: Significantly increases drowsiness with both medications—especially dangerous with Dramamine
- Sedatives and sleep aids: Benzodiazepines, opioids, and sleep medications compound sedation effects
- Other antihistamines: Benadryl, Zyrtec, Allegra—don't stack antihistamines
- Anticholinergic medications: Oxybutynin, tricyclic antidepressants, some antipsychotics—additive anticholinergic effects
- MAO inhibitors: Can intensify and prolong the anticholinergic effects of both drugs
Who Should Avoid These Medications
- Elderly patients: Higher risk of confusion, falls, and urinary retention from anticholinergic effects
- Glaucoma (narrow-angle): Anticholinergic drugs can increase eye pressure
- Enlarged prostate (BPH): Risk of urinary retention
- Severe liver or kidney disease: May affect drug metabolism
- Children under 2 (Dramamine) or under 12 (Bonine): Not recommended OTC
Best Choice for Specific Travel Scenarios
Cruises
Winner: Bonine. Once-daily dosing means you take it in the morning and forget about it. Less drowsiness lets you enjoy activities. Many experienced cruisers and cruise ship medical staff recommend meclizine as the go-to OTC option. Start the night before embarkation for best results.
Car Travel (as a Passenger)
Winner: Bonine for most people. You'll stay alert enough to enjoy the trip. Use Dramamine Original only if Bonine doesn't provide enough relief and you're comfortable napping through the drive.
Road Trips (as the Driver)
Winner: Bonine (with caution). Drivers should never take Dramamine Original. Bonine is the less-drowsy option but still test your reaction before getting behind the wheel. Non-medication alternatives (fresh air, looking at the horizon, ginger) are safest for drivers.
Flights
Winner: Bonine for daytime flights, Dramamine for red-eye flights (where sleeping through it is the plan).
Amusement Parks
Winner: Bonine. You need to stay alert and active. Take it 1 hour before arriving.
Children (Ages 2–11)
Winner: Dramamine (by default). Children's Dramamine (dimenhydrinate) is approved for ages 2+. Bonine is only approved OTC for ages 12+. For children, always use the children's formulation and consult a pediatrician for proper dosing.
What About Dramamine Non-Drowsy?
Dramamine also makes a "Non-Drowsy" formula containing ginger extract (1,000 mg) instead of dimenhydrinate or meclizine. It's a natural option that some people find helpful for mild motion sickness, but it is not an antihistamine and works through a completely different mechanism. Clinical evidence for ginger is mixed—it may help with nausea but is generally less effective than meclizine or dimenhydrinate for moderate to severe motion sickness.
If you want zero drowsiness risk and have mild symptoms, the ginger formula is worth trying. For reliable prevention of moderate to severe motion sickness, meclizine (Bonine) remains the better choice.
The Bottom Line
- Bonine is the better choice for most travelers: Less drowsy, once-daily dosing, equally effective at preventing motion sickness
- Dramamine Original is stronger but very sedating: Best for severe motion sickness when you can afford to be drowsy (e.g., as a passenger)
- "Dramamine Less Drowsy" = Bonine: Same active ingredient (meclizine 25 mg)—buy whichever is cheaper
- Take BEFORE travel: Both work best when taken 30–60 minutes before motion exposure, not after nausea starts
- Never combine them: Both are antihistamines—combining increases side effects without improving effectiveness
- For children under 12: Dramamine is the only OTC option; Bonine is not approved for this age group
For most people, Bonine offers the best balance of effectiveness and tolerability. You get reliable motion sickness prevention without spending your entire trip fighting to stay awake. Pack it alongside your passport and sunscreen—your stomach will thank you.
