A systematic review «Jung AC, Staiger T, Sullivan M. The efficacy of selective serotonin reuptake inhibitors for the management of chronic pain. J Gen Intern Med 1997 Jun;12(6):384-9. »1 including 19 studies (10 of headache, n=550; 3 of diabetic neuropathy, n=83; 3 of fibromyalgia, n=83; 3 of mixed chronic pain, n=119) was abstracted in DARE. The results were inconsistent in all studies with the exception of mixed chronic pain where SSRIs were more effective than placebo.
Comment: The quality of evidence is downgraded by sparse data and inconsistency.
