Low-dose naltrexone (LDN) is widely used to manage chronic pain, inflammation, and autoimmune conditions. Unlike standard naltrexone dosages for opioid or alcoholics (50-100 mg), LDN is prescribed at much lower doses (0.5-4.5 mg).
LDN is generally well tolerated, but some people experience temporary or mild side effects, especially during the adjustment period.
This guide explores the possibilities Side effects of low-dose naltrexonehow long they last, and practical tips for managing them. Let’s read!
