Important Safety Information: Low Dose Naltrexone (LDN)

Common effects include vivid dreams, sleep disruption, headache, and nausea, most often in the first weeks. Naltrexone blocks opioid medication, including opioid pain relief in an emergency. Carry documentation that you take it. Liver function should be monitored, though clinically significant liver effects are rarely reported at low doses. This is an off-label use of an approved drug.
