Fibromyalgia (FM), one of the most common chronic pain syndromes, is characterized by diffuse musculoskeletal pain, in addition to extreme fatigue and mood and sleep disturbances. The cause(s) of fibromyalgia is not known but it usually affects women more than men, it has a genetic predisposition and its prevalence in the general population is approximately 7%.

 

Effective treatment for the pain and other symptoms of fibromyalgia has remained elusive, despite three FDA-approved prescription medication. These prescription medications as well as opioids are often ineffective or not well tolerated leaving many patients suffering from significant impairment in the quality of their lives to turn to alternative medications.

 

The recent changes in access to medical marijuana and marijuana-based medication offers hope for a new alternative treatment for many of the symptoms associated with FM.

Mariuana (Cannabis) – Fibromyalgia

 

Cannabis Research

The current state of medical marijuana research, especially in the field of fibromyalgia, is based mostly on studies using the cannabis plant, whether smoked, vaped or ingested, in which virtually nothing is known about the dosages associated with use, i.e. how much THC, CBD and other constituents were used and how often. This leaves a serious weakness in applying the findings to the use of marijuana-based products which have fixed amounts and ratios of constituents. Most cannabis research is in the form of observational studies with very few randomised controlled trials to guide management of fibromyalgia with specific cannabis-based treatments.

 

Observational studies are those in which data is reviewed by an investigator who observes individuals without manipulation or intervention and draws inferences from a population where no independent variables are under the control of the researcher. Observational studies can determine if there are associations between an activity and an outcome but cannot identify or confirm cause and effect. This is in contrast to randomised controlled trials (RCTs) where investigators do intervene and look at the effects of the intervention on an outcome. RCTs are useful in determining causal relationships between treatment and outcome such as whether a medication actually works for a particular conditi0n.

 

Fibromyalgia Treatment with Cannabis

A 2014 online survey of over 1,300 fibromyalgia patients conducted by the National Pain Foundation and published in the National Pain Report indicated that while over 70% of the people who responded to the survey indicated they had not tried medical marijuana, but of those who did try medical marijuana said it was far more effective than any of the FDA-approved prescription medications for fibromyalgia (Cynbalta, Lyrica, Savella).

 

Sixty-two percent of respondents who had tried cannabis considered it very effective for treating their fibromyalgia symptoms and another 33% said it helped a little, while only 5% said it did not help at all. Some responders reported that nothing had worked for them apart from marijuana. Adverse effects reported included brain fog with use of medical marijuana.

 

A 2018 study of 26 patients with FM treated for an average duration of  10 months, with a median duration of 3 months. No patient ceased cannabis treatment. All the patients smoked or inhaled cannabis but the study did not identify an analysis of the cannabis content.  In the study group, 13 patients (50%) ceased taking any medication other than cannabis. Twelve patients (~46%) reduced the dose/number of medications  they had been taking for their FM, including opioids, Lyrica and benzodiazepines, by at least 50% as compared with the dose/number of medications prior to cannabis treatment. In some cases, the improvement was so marked that the patients completely ceased treatments they had taken previously.

 

The main finding of the study was that cannabis treatment was associated with significant favorable outcomes in every item evaluated, including pain, sleep, energy and quality of life. It was noted that the patients expressed dramatic improvements such that the researchers commented that they “Very rarely  encountered such responses in real-life medicine.”

 

Examples of the patients’ responses included: “I wish I had received this treatment when I was first diagnosed with fibromyalgia,” “I returned to be the same person as before,” “I regained my health,” and “This is a miraculous treatment.”

 

There were no serious adverse effects in this study. The patients reported a few mild adverse effects, including dry mouth, redness of the eyes, and feeling hungry. These symptoms appeared at the start of the treatment but were usually transient, lasting only a few weeks, and were mainly associated with smoking the cannabis. Many patients adapted to feeling hungry by eating prior to the use of cannabis.

 

Fibromyalgia Treatment with Pharmaceutical Cannabinoids

Pharmaceutical Cannabinoids – THC

THC (delta-9-tetrahydrocannabinol), the major cannabinoid constituent of cannabis, has only limited research as a singular agent for treating fibromyalgia. A 2006 study evaluated just nine fibromyalgia (FM) patients who received a daily dose of 2.5-15 mg of THC, starting with a 2.5mg/day dose with a weekly dose increase of 2.5 mg up to a maximum 15 mg/day dose, as long as no side effects were reported. Daily-recorded pain of the FM patients was significantly reduced but researchers recommended further studies be done prior to concluding definitive effectiveness.

 

In 2009 a multicenter survey was performed evaluating 172 patients treated with an average of 7.5 mg/day of THC over 7 months. Of these, 48 patients prematurely withdrew due to side effects, insufficient analgesia, or expense of therapy. In the end, 124 patients were assessed for changes in pain intensity,  quality of life, anxiety and depression. Pain intensity improved significantly with the THC treatment. Opioid doses were reduced and patients perceived THC therapy was effective with tolerable side effects. About 25% of the patients, however, did not tolerate the THC treatment.

 

Pharmaceutical Cannabinoids – Nabilone

Nabilone is a synthetic cannabinoid, FDA-approved in the United States and approved for use in Canada, Mexico, and the United Kingdom for the treatment of severe nausea and vomiting associated with chemotherapy. Evidence is emerging for the use of nabilone in the management of different pain conditions including fibromyalgia. A systematic review of the Cochrane Library databases (updated July 23, 2015) identified eight randomized controlled trials, two prospective cohort trials, and one retrospective chart review evaluating cancer pain, chronic noncancer pain, neuropathic pain, fibromyalgia, and pain associated with spasticity. Nabilone was most commonly used as adjunctive therapy but overall nabione treatment led to small but significant reductions in pain. The most common side effects included euphoria, drowsiness, and dizziness but nabilone was rarely associated with severe side effects that required discontinuation of use. The likelihood of abuse was considered low. Although the optimal role of nabilone in the management of pain is yet to be determined, nabilone is generally considered to be a third-line agent.

 

A Cochrane review article published in 2016 reviewed randomised controlled trials of at least four weeks’ duration that evaluated any formulation of cannabis products used for the treatment of adults with fibromyalgia. Highest quality evidence was obtained from studies with at least 200 participants and of eight to 12 weeks duration. Lesser quality evidence was obtained from smaller studies that were considered at some risk of bias. The primary outcomes in the review were participant-reported pain relief of 50% or greater.

 

Nabilone was compared to placebo and to amitriptyline in two small studies with 32 and 40 participants and study duration of four to six weeks. Nabilone was provided with a bedtime dosage of 1 mg.  Neither study reported participants experiencing at least 30% or 50% pain relief or who were very much improved.

 

Some studies, though of very low quality, provided evidence of greater reduction of pain and limitations of health-related quality of life compared to placebo. There were no significant differences to placebo found for fatigue and depression. Better effects of nabilone on sleep than amitriptyline (Elavil) were reported. More participants dropped out due to adverse events in the nabilone group (4/52 participants) than in the control groups (1/20 in placebo and 0/32 in amitriptyline group). The most frequent side effects were dizziness, nausea, dry mouth and drowsiness (six participants with nabilone). There were no reported serious side effects.

 

No relevant studies evaluating fibromyalgia treatment with herbal cannabis, plant-based cannabinoids or synthetic cannabinoids other than nabilone were found. The authors of the Cochrane review concluded that there is no convincing, unbiased, high quality evidence that nabilone is of value in treating people with fibromyalgia and the tolerability of nabilone was low.
