Can motion sickness be prevented or reversed?

Motion sickness occurs when signals from the eyes, inner ear, and body do not match during movement. Nausea, dizziness, sweating, headache, and vomiting can follow. It may happen on a car journey, boat, aircraft, or amusement ride, and can affect people who have not previously felt it.

The symptoms are generally temporary, but repeated vomiting can cause dehydration. Other illnesses can also cause nausea or vomiting, so symptoms that continue after travel deserve assessment rather than being assumed to be motion sickness.

Choose a seat with the least movement when possible, look towards the horizon, keep your head supported, and avoid reading or using a screen. Fresh air, small light meals, and regular sips of water may help; heavy meals and alcohol can make symptoms harder to manage.

Ask a pharmacist or clinician about prevention medicine before travelling, because timing, side effects, age, pregnancy, and other medicines affect the choice. A Travel Health Consultation can help if you have a long journey or frequent episodes.

Get urgent help for severe dehydration, fainting, confusion, blood or green material in vomit, severe abdominal pain, chest pain, or a sudden severe headache. Arrange medical advice if vomiting continues after movement stops, episodes are becoming frequent, or you cannot keep fluids down.

Ask which preventive option fits your health history, when to take it, whether it causes drowsiness, and what to do if vomiting prevents you keeping medicine down. Mention pregnancy, glaucoma, prostate symptoms, and any regular medicines.
