    • Current use of the following drugs:
    • Antihypertensive drugs
    • Neuroleptics
    • Monoamine oxidase inhibitors
    • Tizanidine

    • Bupropion
    • Mirtazapine
    • Tricyclics: daily dose greater than 75mg amitriptyline or equivalent
    • Benzodiazepine: daily dose greater than 5mg diazepam or equivalent
    • Asthmatic medicine, including inhaler
    • Participants may be included after minimum of 4 weeks of physician prescribed termination of these drugs
    The main purpose of this study is to collect pilot feasibility study data for the use of low dose propranolol for helping treat fibromyalgia. The investigators plan to compare 20mg twice a day dosage of propranolol and 10mg twice a day dosage of propranolol to placebo. The design is a 3 arm, double blind randomized control trial. The investigators will also test ECG and respiratory assessment as a part of the safety screening and the feasible assessment of respiratory sinus arrhythmia.

    Propranolol is not indicated to treat pain. However, the previous studies showed that low dose propranolol can re-regulate the adrenergic dysfunction and reduce pain in people with chronic musculoskeletal pain. However, the investigators are not aiming to develop a new indication of the drug.
