The timing of Low-Dose Naltrexone (LDN) administration, specifically during the evening, is a common recommendation within prescribing protocols. This practice stems from the drug’s mechanism of action and how it interacts with the body’s natural circadian rhythms and opioid system. Taking LDN before sleep is believed to maximize its therapeutic effects in many individuals.
The rationale behind this timing focuses on LDN’s ability to briefly block opioid receptors. This temporary blockade, occurring primarily overnight, is hypothesized to trigger an upregulation of endogenous opioid production. This increase in naturally produced opioids is associated with immune modulation, pain reduction, and potential benefits for various autoimmune and inflammatory conditions. Furthermore, administering LDN at night aligns with the body’s nocturnal repair and restorative processes, potentially enhancing the drug’s impact on these processes. Historically, initial clinical observations suggested improved outcomes when LDN was taken closer to bedtime.
