Today my Doctor told me to choose between Lamictal and a new drug (supposedly new) called Vimpat. Does anyone know about Vimpat. I am on Neutontin and Topamax and am having problwms with Topamax so they decided I may be able to change. I was on Keppra and topamax, but the side effects from the Keppra were devastating. The Topamax works for the seizures and my migraines. Now they will use Inderal for the Migraines and either of the two drugs above for the seizures. I have not used either one. I hope someone can tell me about both drugs. I am nervous about changing.
