#AskTheExpert My daughter when she travels in car. after sometime she usually getting vomiting. what to do in this case?

A. If you're planning a car trip, ask your child's doctor about using an over-the-counter antihistamine, such as dimenhydrinate (Dramamine) or diphenhydramine (Benadryl), to prevent car sickness. Both medications work best if taken about an hour before traveling.
