Low-dose naltrexone

Low-dose naltrexone (LDN) refers to daily naltrexone dosages that are roughly one-tenth or less of the standard opioid addiction treatment dosage. Most published research suggests a daily dosage of 4.5 mg, but this can vary by a few milligrams.[1] Low-dose naltrexone has been studied for the treatment of multiple chronic pain disorders including fibromyalgia, multiple sclerosis, Crohn’s disease, Long COVID, and complex regional pain syndrome.[2]

Naltrexone is approved by the Food and Drug Administration (FDA) for medication-assisted treatment of alcoholism and opioid use disorders.[3] Bernard Bihari's initial off-label usage of naltrexone in doses ranging from 1.5 mg to 3 mg as an adjuvant therapy for acquired immune deficiency syndrome (AIDS) in the 1980s led to the introduction of LDN into clinical practice.[4] Due to a lack of large-scale clinical trials and standardized research aimed at determining appropriate indications for LDN, it has remained an off-label option.[5]
