YES. Low-dose naltrexone is as effective as amitriptyline in the treatment of painful diabetic neuropathy and has a superior safety profile (strength of recommendation [SOR], B; single randomized controlled trial [RCT]). Low-dose naltrexone significantly reduced pain by 32% in inflammatory conditions and 44% in neuropathic conditions (SOR, B; single retrospective cohort study). Doses as low as 5.4 mg were found to reduce pain in 95% of patients with fibromyalgia (SOR, B; single prospective dose-response study).
