My neuropathy is from a bout of necrotizing vasculitis and I've had neuropathy pain for five years. I'm currently taking 2400mg of gabapentin. In the past I've taken Keppra, Oxcarbazepine, and Topomax (one at a time) with the gabepentin. They have all worked to some extent to ease the pain and discomfort, but gabapentin alone works pretty well. I've taken all this other stuff because my neurologist has been trying to find a "cocktail" of medications that will make me feel better as my pain has gotten worse over the last year or so. Good luck finding the right thing!
