Medication, eating or changing position can treat motion sickness, according to WebMD. Specifically, eating several dry crackers, drinking ginger ale, getting fresh air, lying down or keeping the head still may help improve symptoms of motion sickness.
Medications that help treat motion sickness include scopolamine, antiemetics and antihistamines, according to WebMD. Scopolamine comes as a patch that the user places behind the ear to relieve nausea and vomiting. Antiemetics are medications that reduce nausea, and antihistamines may cause drowsiness. Recommendations that may help avoid motion sickness include minimizing head movements, avoiding alcohol and heavy meals prior to travel, and avoiding strong odors and spicy foods during travel.
