Effects of Venlafaxine on Chronic Neuropathic Pain Following Spinal Cord Injury

Summary

The purpose of this study is to evaluate the pain-relieving effects of venlafaxine hydrochloride (Effexor) in chronic neuropathic (burning, shock-like, electric) pain after spinal cord injury (SCI). Although a number of medications have been used to treat SCI pain, no drug has been consistently helpful, and, therefore, many people with SCI continue to have difficult chronic pain. Venlafaxine is a new anti-depressant drug that has not been tested for use in SCI neuropathic pain, but has been helpful for other types of neuropathic pain.
