I just got this from babycenter it says never to give your toddler:


Anti-nausea medications
Don't give your toddler an anti-nausea medication (prescription or OTC) unless her doctor specifically recommends it. Most bouts of vomiting are pretty short-lived, and children usually handle them just fine without any medication. In addition, anti-nausea medications have risks and possible complications. (If your child is vomiting and begins to get dehydrated, contact her doctor for advice on what to do.)
