Management of Fibromyalgia Syndrome
Don L. Goldenberg, MD
Context The optimal management of fibromyalgia syndrome (FMS) is unclear and
comprehensive evidence-based guidelines have not been reported.
Objective To provide up-to-date evidence-based guidelines for the optimal treat-
ment of FMS.
ized controlled trials and meta-analyses of randomized controlled trials) of FMS was made using Cochrane Collaboration Reviews (1993-2004), MEDLINE (1966-2004), CINAHL (1982-2004), EMBASE (1988-2004), PubMed (1966-2004), Healthstar (1975- 2000), Current Contents (2000-2004), Web of Science (1980-2004), PsychInfo (1887- 2004), and Science Citation Indexes (1996-2004). The literature review was per- formed by an interdisciplinary panel, composed of 13 experts in various pain management will fit the classification criteria for fi- disciplines, selected by the American Pain Society (APS), and supplemented by se- lected literature reviews by APS staff members and the Utah Drug Information Ser-vice. A total of 505 articles were reviewed.
Data Synthesis There are major limitations to the FMS literature, with many treat-
ment trials compromised by short duration and lack of masking. There are no medicaltherapies that have been specifically approved by the US Food and Drug Administra- tion for management of FMS. Nonetheless, current evidence suggests efficacy of low- dose tricyclic antidepressants, cardiovascular exercise, cognitive behavioral therapy, and patient education. A number of other commonly used FMS therapies, such as trig- ger point injections, have not been adequately evaluated.
ogy classification criteria for the diag- Conclusions Despite the chronicity and complexity of FMS, there are pharmaco-
logical and nonpharmacological interventions available that have clinical benefit. Based on current evidence, a stepwise program emphasizing education, certain medica- tions, exercise, cognitive therapy, or all 4 should be recommended.
using these criteria have found an FMSprevalence of 2% in the United States,including 3.4% of women and 0.5% of tologists (after osteoarthritis), yet rheu- Author Affiliations: Department of Rheumatology,
