Open pilot study on oxcarbazepine for the treatment of notalgia paresthetica.

Notalgia paresthetica is a sensory neuropathy typically presenting with pruritus on the back. There is currently no effective treatment for this disorder. We describe a single patient who responded to oxcarbazepine, and a subsequent trial in another 4 who also responded. Although the number of patients in our study is small, we believe further trials are warranted to determine the efficacy of oxcarbazepine in this disorder.
