Conventional analgesics have limited efficacy in the management of neuropathic pain. An adjuvant analgesic is a drug that has a primary nonpain indication but which may be analgesic in certain circumstances, and many of these have established a role in the pharmacological treatment of neuropathic pain. ⋯ Cost-effectiveness data are absent for the vast majority of these drugs. Pharmacological treatments should be used as part of a multimodal therapeutic programme for the management of neuropathic pain.
