Bonine vs Gravol: Two Brands, Two Different Antihistamines
Bonine contains meclizine HCl 25 mg in its standard US chewable product. Original Gravol contains dimenhydrinate. They are different first-generation antihistamines, and both can cause drowsiness. US meclizine labels commonly direct adults and children 12 and over to take 1 to 2 tablets once daily, while dimenhydrinate products are typically shorter-acting and may be redosed according to their own label. Gravol also sells ginger and other variants, so read the active-ingredient panel on the exact box. In Canada, meclizine is generally not stocked as a standard retail product. Ask a pharmacist which option and dose fit you.
Key facts
- Standard Bonine contains meclizine HCl 25 mg, while Original Gravol contains dimenhydrinate, so they are different drugs.
- Both are first-generation antihistamines and both can cause drowsiness.
- Current US meclizine labels commonly direct ages 12 and over to 1 to 2 tablets once daily, with the first preventive dose 30 to 60 minutes before travel.
- Gravol sells multiple formulations, including ginger products, so the active-ingredient panel matters more than the brand name.
- Meclizine is generally not sold as a standard retail product in Canada, where it was historically known as Bonamine.
Bonine and Gravol sit in the same motion-sickness conversation, but they are not two regional names for the same tablet. Standard Bonine in the United States contains meclizine. Original Gravol in Canada contains dimenhydrinate, the same active ingredient found in Dramamine Original in the United States.
That difference changes how often the labels allow a dose, how the products are marketed, and what is actually available where you live. It does not produce a universal winner. Both medicines can cause drowsiness and have precautions that depend on age, pregnancy, other medicines and health conditions, so the decision belongs with a doctor or pharmacist.

The active ingredients are different
The current Bonine chewable label lists Meclizine HCl 25 mg as its active ingredient. Meclizine is an antihistamine used for nausea, vomiting and dizziness associated with motion sickness. Original Gravol lists dimenhydrinate, another first-generation antihistamine.
The front of the box can make this more confusing than it needs to be. Gravol sells multiple products, including ginger formulations that do not contain dimenhydrinate. Dramamine sells a Less Drowsy product that contains meclizine, the same drug as Bonine. Compare active ingredients, not only brand names.
Timing and drowsiness are the practical differences
A current US over-the-counter meclizine label directs adults and children 12 and over to take 1 to 2 tablets once daily, with the first preventive dose half an hour to an hour before travel. It warns that drowsiness may occur, alcohol and sedatives can increase it, and users should be careful driving or operating machinery.
Dimenhydrinate products are generally shorter-acting and their labels allow repeat dosing during the day. The exact Canadian Gravol directions depend on the product and age group, so use the label on the package you are holding rather than importing an American Dramamine dose from the internet. 'Less drowsy' does not mean non-drowsy, and neither product should be treated as safe for driving until you know how it affects you.
The Canada question changes the comparison
Gravol is widely recognized in Canada. Meclizine, historically sold there as Bonamine, is generally not available as an ordinary retail medicine in the Canadian market. That means a Canadian search for Bonine or Bonamine versus Gravol may be comparing a locally available product with one found on an American website.
Availability changes and some pharmacists may discuss compounded or alternative options. Ask locally before planning a trip around meclizine. Crossing a border does not remove the need to check whether a medicine is appropriate for you or whether it can be brought back legally.
A drug-free option sits outside the antihistamine trade-off
If the real goal is to avoid drowsiness rather than choose between two pills, Dizzout is a different category. It is a drug-free motion-sickness app that plays precisely calibrated audio through any wired or Bluetooth headphones. There is no antihistamine and no drug-related drowsiness. It is designed for use before travel or after symptoms start, and Dizzout states relief in about 90 seconds.
Dizzout is free to try on iOS and Android, with a subscription for full access. It is not a medicine and this page does not claim it is medically superior to either pill. It is simply another option to consider alongside label-directed medicine and advice from a pharmacist.
When to use which
The useful choice is not 'which brand wins' but which active ingredient, timing and side-effect profile fits your situation. Bonine's meclizine is commonly labelled once daily and marketed as less drowsy, but drowsiness can still occur. Original Gravol's dimenhydrinate is shorter-acting and commonly carries a stronger sedation reputation. Ask a doctor or pharmacist before choosing for a child, during pregnancy, for an older adult, or alongside other medicines. Follow the exact label in your country. If avoiding an antihistamine is the priority, a drug-free option such as Dizzout can be considered alongside that advice.

Frequently asked questions
Is Bonine the same as Gravol?
No. Standard Bonine contains meclizine HCl 25 mg. Original Gravol contains dimenhydrinate. Both are first-generation antihistamines used for motion sickness, but they are different drugs with different label directions.
Is Bonamine vs Gravol the same comparison?
Usually yes. Bonamine was a Canadian brand name for meclizine, and people often type it when they mean Bonine or meclizine. Gravol is dimenhydrinate in its original medicine formulation. Meclizine is generally not sold as a standard retail product in Canada now, so ask a pharmacist what is locally available.
Which is less drowsy, Bonine or Gravol?
Meclizine products such as Bonine are commonly marketed as less drowsy than dimenhydrinate products such as Original Gravol. Less drowsy is not non-drowsy: current meclizine labels still warn that drowsiness may occur and advise caution when driving. Individual response varies.
Can I take Bonine and Gravol together?
Do not combine two motion-sickness antihistamines unless a doctor or pharmacist specifically tells you to. Both can cause drowsiness and have overlapping precautions. Bring the exact packages or active-ingredient names when you ask.
Bonine and Gravol are different antihistamines, not competing labels on one drug. Bonine is meclizine and Original Gravol is dimenhydrinate. Read the active ingredient, use the country-specific directions, and let a pharmacist handle the personal choice. If the comparison began because you want no antihistamine drowsiness at all, a drug-free option belongs in the conversation too.
