My dr prescribed zofran for a plan trip we have tommorow for nausea since I get motion sickness. I usually take dramamine but can't since I am pregnant. They said it can cause drowsiness. I know zofran works really well for naseau but is it worth taking it for possible side effects. Think it will work for motion sickness? I still get boughts of naseau and morning sickness and I really don't want to puke on the plane.
