Tricyclic antidepressants have demonstrated analgesic efficacy for NP entities such as post-herpetic neuralgia and diabetic neuropathy, and their use is extrapolated to other NP entities (Mercadante, Arcuri, Tirelli, Villari, & Casuccio, 2002); they were found to be useful for phantom limb pain in children as early as 1989 (Rogers, 1989), taking effect within 1 week at doses lower than those required for depression (Mercadante, Arcuri, Tirelli, Villari, & Casuccio, 2002).
