who are you?Hello Dr. Rynne, I am in Canada and the Gov't has a habit of changing the medications it will help seniors with coverage of the cost. I am allergic to Dyes and lots of other things. So with so little information, here is the question . I have been taking PMS-Topirimate the cost is quite high so the suggested one is Accel-Topiramate. Do you think I should be concerned, I don't want to start getting Migraines again, as they were depiletating every day. Please I would appreaciate any advice
