Preliminary safety and effectiveness of psilocybin-assisted therapy in adults with fibromyalgia: an open-label pilot clinical trial

Frontiers in Pain Research March 18, 2025 Jenna McAfee, Avinash Hosanagar, Vijay Tarnal et al. 18 citations

In a small open-label pilot trial, five people with fibromyalgia received two doses of psilocybin (15 mg and 25 mg) along with psychotherapy. The treatment was well-tolerated: there were temporary increases in blood pressure or heart rate during dosing that returned to normal, no serious adverse events, and four of five participants had short-lived headaches. One month after the second dose, participants reported large reductions in pain severity, pain interference, and sleep disturbance. One participant rated their symptoms as very much improved, two as much improved, and two as minimally improved. Recruitment stopped early due to generalizability concerns and changing FDA guidance, but the results suggest psilocybin-assisted therapy is safe for fibromyalgia and warrants larger trials.

Going Underground: Demographics, Services, and Best Practices Endorsed by Practitioners Providing Support for Naturalistic Psychedelic Use

Journal of Psychoactive Drugs September 19, 2024 Anne Baker, Niloufar Pouyan, Julie Barron et al. 9 citations

A survey of 107 people who provide psychedelic support services outside clinical trials found that 40.2% held a full or in-progress license and 44.9% lacked a relevant graduate degree. Almost all practitioners pre-screened clients, offered preparation, integration, and trip-sitting, and used primarily non-directive approaches. Clients most often consumed psilocybin for conditions similar to those in clinical research. Practitioners perceived mostly positive symptom changes, though a small proportion reported worsened personality disorder symptoms. Further research on naturalistic psychedelic-assisted therapy is needed.

Psychedelics and chronic pain: self-reported outcomes on changed substance use patterns and health following naturalistic psychedelic use

British Journal of Pain February 11, 2025 Anne Baker, Stephanie Lake, Philippe Lucas et al. 7 citations

Most people with chronic pain who use psychedelics to self-treat report ceasing or decreasing their use of other substances, especially alcohol and prescription opioids. In a survey of 466 adults, 86.3% said they stopped or reduced at least one non-psychedelic substance because of psychedelic use, with 21.2% reporting the decrease lasted over 26 weeks. Alcohol (71.1%) and prescription opioids (64.1%) were most often decreased or stopped. Illicit opioids (27.8%) and cannabis (21.5%) were more likely to be increased or initiated. Psilocybin was rated the most effective psychedelic for physical and mental health symptoms. Findings suggest potential benefits and risks of naturalistic psychedelic use for chronic pain.

Preliminary safety and effectiveness of psilocybin-assisted therapy in adults with fibromyalgia: An open-label, pilot clinical trial

November 4, 2024 Jacob S. Aday, Jenna McAfee, Deirdre A. Conroy et al. preprint

In a small open-label proof-of-concept trial, five adults with fibromyalgia received two doses of psilocybin (15 mg and 25 mg) two weeks apart, along with psychotherapy sessions. No serious adverse events occurred; transient blood pressure or heart rate elevations during dosing resolved by the end of treatment, and four of five participants had temporary headaches. One month after the second dose, participants reported clinically meaningful improvements in pain severity, pain interference, and sleep disturbance. One participant rated their symptoms as very much improved, two as much improved, and two as minimally improved. Improvements were also seen in fibromyalgia symptoms, anxiety, and fatigue. The findings suggest psilocybin-assisted therapy is well-tolerated and warrants larger randomized controlled trials.
