5. Study Description
Brief Summary
The main objective of this study is to test if naltrexone, when taken in low doses, has an anti-inflammatory effect that may be associated with positive clinical outcomes in people with chronic fatigue syndrome (CFS). In part, the present study, is a continuation of prior work in which we showed that chronic fatigue symptoms are associated with immune activity, and that low-dose naltrexone might exert anti-inflammatory effects in fibromyalgia, which is thought to share some pathophysiological and clinical characteristics with CFS.

Masking Description
Double-blind trial. An encrypted and password-protected database will contain (1) information about individual group assignment, and (2) blister pack codes (medication will be dispensed in blister packs by investigators based on these codes). An investigator not involved with data collection or participant interactions will randomly assign individuals to the treatment group and provide blister pack ID codes for each individual.
