We are going on a cruise next month and I am trying to decide what to take along for sea sickness just in case we will need it. My question is-is meclizine and compazine related drugs? My daughter was prescribed compazine during a pout with the stomach flu and had a bad reaction to it. I didn't know since meclizine is used to calm stomachs and ends in "zine" if it would have the same effect on her. Thanks for any info.
