One small (10 subjects) uncontrolled trial using low dose Naltrexone
(ldn) for fibromyalgia
showed some promise.
The study showed that 7 out of 10 study subjects with fibromyalgia had a 30% reduction in pain. Additional studies need to be done to see if it is really effective. The drug cannot be used if the patient is on opioid pain medications. Discuss with your doctor.
