Well, I was invited to participate in a study for Vimpat (lacosamide) as it is not readily available in the U.S. as yet and I guess they want to use us as gunea pigs first. Although, my epileptologist told me that if my current "brain candy" (Keppra and Zonisamide) didn't start working the way it should, he would put me on Vimpat.
Anyway, from what I've read, Vimpat looks promising...as in the side-effects aren't as hideous as, say, Keppra or Topamax or as delibitating as Lamictal or Carbatrol can be for some. Hey, I've been on 7 AEDs in the three years since my diagnosis and am a firm believer they all suck out loud. So I hold out hope that lacosamide is a winner for many!
There's even talk that it can be used as a mono-therapy med!
Best of luck! Let us know how you do on it...soon us slow-pokes in the U.S. will be able to take it, too!
