How does hydroxyzine treat symptoms of motion sickness?

Nausea and vomiting caused by motion sickness can be prevented or reduced by taking hydroxyzine 30 minutes before engaging in an activity that triggers motion sickness. Hydroxyzine can cause drowsiness, so it's important to weigh the benefits and side effects before taking the drug. It's also important to take the prescribed dose with food.
