Certain behavioral strategies are often recommended to help prevent and minimize the symptoms of motion sickness, as it is easier to prevent motion sickness than it is to relieve the symptoms. Some of these behavioral strategies include avoiding travel in bad weather conditions (e.g., during storms) and, when traveling, sitting in areas that experience the least amount of movement. This is usually the lowest level in trains and buses, over the wing on airplanes, and close to water level in boats. Other tips that may help prevent motion sickness include sitting in the front seat of the car, looking at a fixed point in the horizon, and avoiding focusing on phones or other screens, maps, or books while traveling in a moving vehicle.  If symptoms are severe or persist despite behavioral changes, medications may be recommended. Some medications used for treating motion sickness are over-the-counter (OTC) antihistamines (e.g., dimenhydrinate, cyclizine, and meclizine) as well as scopolamine, a prescription anticholinergic medication.  While antihistamines are widely used, they may result in a variety of side effects, including increased sleepiness, drowsiness, blurred vision, dry mouth, and urinary retention. Meanwhile, scopolamine, which is often available as a patch that can be placed behind the ear, can cause dilated or widened pupils (i.e., mydriasis), blurry vision, and dry mouth. In general, these medications work best if taken at least one hour before traveling, or as soon as possible after the onset of the symptoms.
