After taking motion sickness medication the patient will have a noticeable dry mouth, because motion sickness medication has the effect of inhibiting glandular secretion, the patient may still be drowsy after taking it, but the patient’s motion sickness will be significantly improved. If the patient takes motion sickness medicine on an empty stomach, it may stimulate the patient’s stomach to appear uncomfortable. Therefore, do not take motion sickness medication on an empty stomach to avoid aggravating the patient’s motion sickness reaction. If dry mouth occurs, patients are advised to drink water appropriately. If drowsiness occurs, you can close your eyes and rest your mind, which will help to improve the patient’s motion sickness. The commonly used motion sickness drugs in clinical practice are Benadryl tablets and ipratropium tablets, which are recommended to be applied selectively by patients, especially those with more severe motion sickness who should be prepared before riding in a car.
