NCT02107014

Brief Summary

We have found that low dose naltrexone (LDN) can substantially reduce pain associated with fibromyalgia syndrome. We believe LDN may work via novel anti-inflammatory channels. The purpose of this study is to determine if LDN lowers inflammatory markers in individuals with fibromyalgia.

Study Arms (1)

Low Dose Naltrexone (LDN)

OTHER

Following a two-week baseline the study drug was administered daily for 8 weeks. Participants were informed that placebo or LDN would be provided during the drug period and that all participants would receive LDN at some point during the study. In fact, all participants received the active LDN (4.5 mg nocte) throughout the drug-administration period.

Drug: Low Dose Naltrexone

Interventions

Naltrexone 4.5 mg p.o. nocte

Also known as: LDN, Naltrexone
Low Dose Naltrexone (LDN)
