Our ped told us take Benadryl for our daughter. He said it works for nausea as well as allergies/itching, etc. Hopefully, we wont have to use it but that's what we are taking.
Here is what I found out from internet research as well:
Benadryl Oral Uses
Diphenhydramine is an antihistamine used to relieve symptoms of allergy, hay fever and the common cold. These symptoms include rash, itching, watery eyes, itchy eyes/nose/throat, cough, runny nose and sneezing. It is also used to prevent and treat nausea, vomiting and dizziness caused by motion sickness. Diphenhydramine can also be used to help you relax and fall asleep.
