Anti-Histamines
Examples: Gravol, Histanil and Life Brand Anti-Nauseant
How they work: Classified as anti-histamines, these medications are to be taken before travelling. They also block the cholinergic transmitters in the brain that control nerve impulses in the gastrointestinal tract and vomiting centre. Dimenhydrinate (the active ingredient in Gravol and Life Brand) offers relief for six to eight hours. Promethazine (the active ingredient in Histanil) may be effective for up to 12 hours, but causes more sedation than dimenhydrinate.
Need to know: Side effects include drowsiness, dry mouth and blurred vision; avoid alcohol and, if you are taking other medications, check with your doctor or pharmacist about interactions. If you are pregnant or lactating, these three products are all safe choices, says Thomson.

Ginger
Examples: Nature’s Way Ginger, Flora Ginger capsules and Quest Turmeric-Ginger Complex
How they work: Ginger contains the compounds gingerol and shogaol, which studies suggest have an anti-nausea and anti-vomiting effect. While the medications mentioned in the other two sections of this article work on the brain, these focus on the gastrointestinal tract, says Nobrega-Porter.
Need to know: Although ginger (at two grams per day) is effective for nausea and stomach upset, it won’t relieve sweating or light-headedness, says Thomson. Follow package directions or, 30 minutes prior to travel, take one gram of powdered ginger mixed with water (don’t exceed four grams daily). Side effects are rare, but check with your doctor first if you are pregnant, lactating or taking other medications.

Anti-Nausea Bracelets
Products such as LYJEE Nausea Wristbands claim to eliminate motion sickness when positioned against acupuncture points known to reduce nausea. Do they work? “Research doesn’t support their efficacy for motion sickness,” says naturopath Kathryn Nobrega-Porter. But some reviewers argue otherwise, claiming it can help prevent everything from motion sickness on cruises to pregnancy-related nausea.
