Low Dose Naltrexone for the
Treatment
of Fibromyalgia
About the Study
Fibromyalgia is a common and potentially debilitating condition that can negatively impact every area of a person’s life. Little in known about the disorder, and there is still a great need for effective treatments.
We are investigating whether low-dose naltrexone (LDN) is one such treatment that many alleviate the symptoms of fibromyalgia (pain, fatigue, weakness, sleep disorders, problems concentrating). LDN may work be restoring balances in the nervous and immune systems.
While some physicians have been using LDN for many years to treat Fibromyalgia and other disorders, there has never been a scientific study of how well the drug works in fibromyalgia. Studies such as this are a necessary step to having an investigational drug become a mainstream treatment. Your participation is a vital part of the search for an effective fibromyalgia treatment.
This study is being funded by the non-profit organization: the American Fibromyalgia Syndrome Association (AFSA). There are no pharmaceutical industry or business interests involved in this study.
