There are many types of motion sickness medications, and the duration of effect of different types of medications varies and cannot be generalized. Motion sickness medication is mainly used to prevent dizziness, nausea, vomiting and other symptoms that occur when a person rides in a car, boat or airplane, and currently common motion sickness medications include motion sickness tablets, stomach reassurance tablets, vertigo stop tablets, scopolamine patches and halohydrin, etc. The duration of effect varies between 4-12 hours depending on the type of medication, and patients are advised to choose the appropriate motion sickness medication depending on the travel time. In general, motion sickness medication needs to be taken on an empty stomach within 0.5-1 hour before driving so that the medication has already reached its effective concentration by the time of the ride. In addition, the number of doses of motion sickness medication should be taken in strict accordance with the instructions and should not be taken again during the duration of the medication; if the trip is long, the medication can be taken once more in the middle. Patients are advised to avoid taking motion sickness medication when they are too full. In addition, since patients tend to sleep after taking motion sickness medication, they should not drive, operate machinery or perform high school work after taking the medication.
