Fibromyalgia

Understanding fibromyalgia

Fibromyalgia is a complex chronic syndrome. Diagnosis relies on clinical assessment and excluding other relevant causes. Management usually combines adapted activity, sleep strategies, psychological support and, where appropriate, medication.

Medical cannabis and fibromyalgia

A medical cannabis assessment should identify the targeted symptom and account for fatigue, cognitive fog and sedating medication. The goal is not to treat every part of the syndrome with one product, but to carefully assess a complementary option.

What the evidence shows

Available reviews report possible signals for pain, sleep or quality of life in some participants. However, randomized trials are few and much of the evidence comes from observational studies.

What it does not establish

Overall certainty remains low because samples are small and products and methods vary. Evidence does not show a cure and cannot predict who will respond.

Points to discuss during the assessment

• The priority symptom: pain, sleep or another goal
• Fatigue and concentration difficulty
• Adapted physical activity and other parts of the care plan
• Sedating medications and work requirements

Important precautions

• Adverse effects can include drowsiness, dizziness, impaired attention, anxiety or a faster heart rate.
• THC can impair driving and the operation of machinery; never drive while impaired.
• Particular caution is required during pregnancy or breastfeeding, with some heart conditions, or with a personal or family history of psychosis.
• Tell the practitioner about all current medications and supplements so possible interactions can be assessed.
