Treatment of Painful Peripheral Neuropathy

Abstract

Treatment of neuropathic pain is the primary focus of management for many patients with painful peripheral neuropathies. Antidepressants and anticonvulsants are the two medication classes most widely studied and represent first-line agents in the management of neuropathic pain. The number of pharmacologic agents and interventional procedures that have shown effectiveness in the treatment of neuropathic pain continues to expand. Pain management should begin with a concerted effort to identify the etiology of the neuropathy, because directed therapy can help alleviate the symptoms. When initiating pharmacotherapy for neuropathic pain, one must individualize treatment and choose an agent that is likely to be tolerated, because adverse events are common for many of these agents. Neuropathic pain management remains challenging because of heterogeneous responses between individuals and the fact that pain relief is rarely complete. However, monotherapy with a well-chosen agent or rational polypharmacy that combines medications with different mechanisms of action will benefit a majority of patients with neuropathic pain.
