Whether opioids are effective for neuropathic pain has been a matter of controversy for decades. Within limits, it is clear that opioids in general are effective for neuropathic pain. Furthermore, there is no evidence that opioids are any less effective for neuropathic pain than for non-neuropathic pain, no evidence that opioids are less effective for neuropathic pain than are other medications, and no evidence that one opioid is any more effective than another for neuropathic pain. It remains uncertain whether opioids are effective for central pain, although they may have a role. Although some patients appear to enjoy long-term benefits, most studies have been short-term. Opioids have an important role in the treatment of neuropathic pain; however, skillful opioid use balances the benefits with management of side effects and prevention and treatment of abuse and addiction.
