Would a selective serotonin reuptake inhibitor (SSRI) improve worsening fatigue, pain, and depression in a patient with fibromyalgia?
SSRIs may have a small to moderate effect on pain (number needed to treat [NNT] = 10), global improvement (NNT = 7), and depression (NNT = 13) in patients with fibromyalgia, but the quality of evidence is very low because of bias and small studies. SSRIs do not reduce fatigue related to fibromyalgia.1 (Strength of Recommendation: B, based on very low–quality randomized controlled trials.)
Fibromyalgia is a poorly understood disorder characterized by chronic, widespread pain that is often complicated by severe fatigue, mood disturbance, and sleep difficulties.2 It affects 2% to 8% of the population, depending on the diagnostic criteria used.2,3 The widespread nature of the pain and confirmation of a biologic basis of the disorder via brain neuroimaging have led clinicians to believe that SSRIs may be helpful in managing the symptoms of the disorder.
This Cochrane meta-analysis reviewed eight double-blind randomized controlled trials that included 383 patients.1 The only SSRIs examined were citalopram (Celexa), fluoxetine (Prozac), and paroxetine (Paxil), and the studies lasted from four to 16 weeks.
