What is the name of motion sickness medication?

Motion sickness medication refers to drugs used to prevent or alleviate symptoms—such as dizziness, nausea, and vomiting—that occur when traveling by car, boat, or airplane. So, what is motion sickness medication called? Below, we provide a detailed explanation.

What Is Motion Sickness Medication Called?

Commonly prescribed medications include dimenhydrinate tablets, phenobarbital–scopolamine tablets, metoclopramide tablets (Reglan), domperidone tablets (Motilium), flunarizine tablets (Sibelium), meclizine (Antivert), and compound belladonna tablets. Motion sickness—also known as kinetosis—is generally believed to result from physical vibrations caused by the motion of vehicles, which temporarily disrupt the vestibular nerve function in the inner ear responsible for balance regulation. Typical symptoms begin with upper abdominal discomfort, followed by nausea, pallor, cold sweats, dizziness, lethargy, increased salivation, and eventually vomiting. For optimal effectiveness, it is recommended to take motion sickness medication approximately 30 minutes before boarding a vehicle. Additionally, choosing a seat near the front of the vehicle—where the field of vision is broader—and opening a window to allow fresh air circulation can significantly help reduce motion sickness symptoms. When symptoms occur, the most important step is to stabilize the head to minimize movement-induced stimulation of the vestibular system. Staying in a well-ventilated area also helps effectively alleviate symptoms.

Knowledge Extension: Causes of Motion Sickness

1. Human balance perception is governed by three key systems: the vestibular apparatus in the inner ear, the cerebellum, and visual input. Among these, the vestibular system in the inner ear plays the most critical role in detecting body position and motion. Motion sickness arises primarily from an imbalance or lack of coordination between the vestibular functions of the two inner ears.

2. Susceptibility to motion sickness varies widely among individuals and is closely linked to personal physical condition. Excessively intense balance stimulation—for example, sudden braking—can trigger dizziness, which is considered a normal physiological response. Motion sickness may also be triggered by factors such as inadequate sleep or common colds. In such cases, improving sleep quality and ensuring adequate rest are usually sufficient for symptom resolution.
