The most frequently used antihistamines to treat motion sickness include cyclizine, dimenhydrinate, meclizine, and promethazine (oral and suppository); nonsedating antihistamines appear to be less effective.
However, many studies show that as a whole, Dramamine is more effective at preventing motion sickness. It's less convenient because of the dosing increments. Another option is scopolamine, which is commonly known as the round patch placed behind one's ear.
If you're susceptible to motion sickness: Focus on the horizon or on a distant, stationary object. Keep your head still, while resting against a seat back. Don't smoke and don't sit near smokers. Avoid strong odors, spicy and greasy foods, and alcohol. Take an antihistamine, which you can buy without a prescription.
Lie down or close your eyes to reduce sensory conflict, and get fresh air to avoid strong smells. Remedies like ginger (tea, sweets, or capsules), acupressure wristbands, or medications can help relieve symptoms. Stay hydrated with water or clear fizzy drinks, and practice deep breathing to calm nausea.
