I've been writting on cancer discussion boards on the internet that anecdotally, drugs like Neurontin are used off-label. Most drugs are prescribed off-label. One must be cautious that off-label remedies are fully discussed with patients and must not do any harm. A number of practioners like to use Neurontin (gabapentin) for all neuropathy. It is already used for diabetic neuropathy and neuropathic pain and (after a work-up and ruling out other causes) they found this to work. But again, do no harm.
