Dramamine is an OTC DRUG that humans have taken for decades for motion sickness. You'd have to check with your vet as to the doseage, but if it were me, I'd rather try something natural. Also again, a warning; try whatever you've going to use at HOME first to see how it affects your pet. You don't want to be in the middle of nowhere trying to give your dog CPR

Rescue Remedy is for both humans and animals. If you get it, be sure to get the one WITHOUT alcohol in the ingredients. They make both formulations. It's made from herbs which is not to say that there aren't side effects possible too....Max hallucinated when I gave it to him

, but other people have had very good results with it.
