Researchers from Stanford University School of Medicine recently reported that low doses of the opioid antagonist naltrexone (ReVia) significantly reduced pain in a study of patients with fibromyalgia. The patients reported an overall decreased amount of pain on naltrexone, as opposed to taking a placebo. Naltrexone is different than other pain medications because it targets the immune pathway of pain. Dr. Jarred Younger, a researcher at Stanford said there was no impact on sleep quality or fatigue from the patients. While naltrexone seems to be an effective, tolerable and inexpensive medicine for fibromyalgia, Younger said further testing is needed.
