Of these first try medications, keppra, lamictal, trileptal
tergretol usually have the fewest side effects on a moderate dose, and
are often the first drugs of choice amongst docs for focal epilepsy. If I were you, though—and I base this on personal experience—I would try either Keppra or Keppra XR, Tegretol, or Trileptal. These medications, on a moderate dose, are not too bad in terms of side effects. But again, everyone is different, and it is all just trial and error, really.
