Healing With Venlafaxine After Injury (HELP)

Results from both animal and human studies suggest that treatment with the serotonin-norepinephrine reuptake inhibitor (SNRIs) venlafaxine may reduce post-MVC pain. In addition, venlafaxine has been shown to be beneficial in reducing posttraumatic stress disorder (PTSD) symptoms, and in some patients PTSD symptoms may contribute to reinforcing pain persistence after trauma. This phase IIB pilot trial will screen patients presenting to the ED after MVC for the presence of severe axial pain (\>4 on a 0-10 numeric rating scale). Sixty of these "high risk" patients will be randomized to venlafaxine vs. placebo, and the ability of venlafaxine to decrease acute and persistent musculoskeletal axial pain will be assessed. Results will be used to design a large-scale RCT assessing the efficacy of venlafaxine intervention in decreasing acute and persistent musculoskeletal pain in high-risk patients presenting to the ED after minor MVC.
