Andrea,   We really can't second guess the doctors who treated her. We don't know the situation well enough, and even our doctor who helps us out with these questions can't say what medications are right just by viewing the information presented online.   I saw in your other questions that we're supposed to know some of your daughter's background, but I can't find any other questions beyond the two you posted today, and no shareposts. So, I don't know how old your daughter is or anything else about her.   Certainly, if the vertigo is a new symptom, other possible causes for it SHOULD be ruled out. Attributing new symptoms to Migraine without ruling out other causes is simply not acceptable.   If her current doctors aren't able to help, you might want to look HERE for our listing of patient recommended Migraine specialists.   Please keep us posted? I'll be away at a conference for a week, but will be checking in.   Teri
