Motion sickness, also commonly known as sea sickness or car sickness, is a set of symptoms - usually nausea and vomiting. These symptoms are caused by passive body movement - where your body is moving without you consciously making it move - in response to actual motion (for example, driving in a car or being in a boat), or the illusion of motion when exposed to virtual movement (for example, virtual reality simulations) and moving visual environments (such as looking out of the window of a moving train). Antihistamines are a type of drug that have commonly been given to people to either treat or prevent motion sickness.
- Antihistamines are likely to reduce the risk of developing motion sickness in susceptible adults under naturally occurring conditions of movement.
- They may be more likely to cause sedation (drowsiness) than placebo (dummy treatment).
- There is very little evidence for their use in children.
- There is no evidence on the use of antihistamines to treat motion sickness symptoms that have already started.
