Over-the-counter medicines such as Dramamine and Bonine can help prevent motion sickness, according to WebMD. Additionally, some types of antihistamines cause drowsiness, which may help fight the feelings of becoming sick.
Another non-medicinal thing a person can do to prevent motion sickness is to never travel on an empty stomach and to eat smaller meals that are low in fat, according to WebMD. Being the driver in a moving vehicle, rather than a passenger, helps as well. However, if a person is unable to drive, the second best things is to keep the head pointed straight ahead in the passenger seat. Finally, wearing a special type of wristband may control feelings of being sickness by applying pressure to the P6 pressure point.
