Use of lamotrigine in glossopharyngeal neuralgia: a case report.

We describe a case of a patient with glossopharyngeal neuralgia (refractory to treatment with carbamazepine, amytriptyline, diazepam, and indomethacin) treated with lamotrigine as monotherapy, the first described, who responded completely to the therapy and did not complain of side effects. The complete analgesic effect was reached at the lamotrigine daily dose of 200 mg per day and was maintained at that dose for additional 6 months, with the blood concentration within the reference range.
