Posted by Celine Fibromyalgia treatments for which there is moderate evidence of effectiveness include the dual-reuptake inhibitors duloxetine, venlafaxine, and fluoxetine, Nonpharmacologic therapies with moderate evidence of effectiveness in fibromyalgia are acupuncture, balneotherapy, biofeedback, hypnotherapy, and strength Evidence to support the use of chiropractic therapy, electrotherapy, manual and massage therapy, or ultrasonography in patients with fibromyalgia is weak.

Fibromyalgia treatments for which there is strong evidence of effectiveness include amitriptyline, 25 to 50 mg at bedtime; cyclobenzaprine, 10 to 30 mg
at bedtime; cardiovascular aerobic conditioning exercise; cognitive behavioral therapy; multidisciplinary therapy as discussed earlier; and patient education,
which may take place in a group format using lectures, written materials, and demonstrations.
at doses of 20 to 80 mg at bedtime, either alone or in combination with a tricyclic antidepressant. Other pharmacotherapies backed by moderate evidence
of effectiveness include pregabalin and tramadol, 200 to 300 mg daily, either alone or in combination with acetaminophen.

diagnosed even if the ACR's tender point criteria are not met, provided the history is highly suggestive.

• Diagnosis is not by exclusion but by using ACR 1990 criteria; it mainly depends on history and physical examination.
• ACR criteria include 2 components: widespread pain above and below the waist including the axial skeleton and presence of 11 tender points among 18 specified
points.
• Complaints at presentation include pain at multiple sites, fatigue, poor sleep, and low back pain that may radiate to buttocks and legs.
• Cognitive impairment such as memory problems, headaches, dizziness, anxiety, and depression may occur.
• The Fibromyalgia Impact Questionnaire is a self-administered instrument that is useful in assessing functional abilities in daily life and outcomes of
treatment. The questionnaire is available at:
http://www.myalgia.com/FIQ/fiq.pdf.
• Systematic palpation at the 18 sites using a force of 8.8 lb (blanching of the examining thumbnail) is part of the physical examination for diagnosis.
• Laboratory testing plays a limited role in diagnosis, and baseline tests used include complete blood count, thyroid-stimulating hormone testing, and comprehensive
metabolic panel.
• Triggers for symptoms include emotional stress, illness, surgery, and trauma.
• Patients with higher count of tender points have been shown to have a higher incidence of childhood adverse experiences such as loss of a parent or abuse.
• Comorbid conditions associated with fibromyalgia include alpha-delta sleep anomaly, altered sleep pattern with increase in stage 1 sleep, reduction in
delta sleep, and sleep disruption, which also occurs with depression.
• Anxiety and depression are the most common comorbidities.
• Prevalence of migraines is higher than in the general population, headaches are a common complaint, and patients may also have irritable bowel syndrome
and abdominal pain.
• Other comorbid conditions include irritable bladder, premenstrual syndrome, restless leg syndrome, temporomandibular joint pain, noncardiac chest pain,
Raynaud's phenomenon, and sicca syndrome.
• The differential diagnoses for fibromyalgia include myofascial pain syndrome, chronic fatigue syndrome, hypothyroidism, metabolic and inflammatory myopathies
(especially in patients taking statins), and polymyalgia rheumatica.
• Pharmacologic treatment remains the mainstay of therapy.
• Tricyclic antidepressants such as amitriptyline, 25 to 50 mg at bedtime, can provide analgesia and treat mood disorders.
• Fluoxetine at 80 mg daily is of limited efficacy, and fluoxetine is more effective in combination with amitriptyline.
• Tramadol may be used for analgesic effect for moderate to severe pain and needs to be titrated to avoid nausea and dizziness.
• Cyclobenzaprine, 10 to 30 mg at bedtime, can improve sleep and reduce pain.
• Pregabalin, a second generation anticonvulsant, has been shown to be effective at 450 mg daily for pain, fatigue, and improving sleep.
• Other strategies of benefit include patient education, cognitive behavior therapy, and some forms of complementary and alternative medicine such as acupuncture
and biofeedback.
