Motion sickness results from a disturbance of the inner ear, leading to a sensation of imbalance. The brain receives signals from the inner ear, eyes, muscles, and joints. When signals are received that do not match, motion sickness may occur. This condition can be caused by the motion of a car, airplane, or boat. If the eyes are unable to send signals of motion to the brain because there is not a window to look out of, while at the same time the inner ear senses motion, motion sickness may occur. Nausea, dizziness, and vomiting may result. Although this condition is not serious, symptoms may cause discomfort in individuals affected. The discomfort may contiinue even after the travel has ceased.
Over-the-counter drugs may be taken to prevent motion sickness. Meclizine (Dramamine, Bonine) is available to help prevent motion sickness. The drug may be taken one hour before traveling for the prevention of motion sickness. In addition, Scopolamine (Transderm Scop) is a patch available with a prescription for prevention. This drug may cause blurred vision. Also, use caution when engaging in activities that require mental alertness or coordination when taking this drug. Avoid drinking alcohol while wearing a scopolamine patch.
