Low Dose Naltrexone

LDN Research Trust Member

Low Dose Naltrexone (LDN) refers to daily dosages of naltrexone that are approximately 10% or less of the typical opioid addiction treatment dosage, commonly up to 5mg. These dosages are compounded at compounding pharmacies and require a prescription. At the low dosage level, naltrexone exhibits paradoxical properties, including analgesia and anti-inflammatory actions, which have not been reported at larger dosages. Studies have shown that it can be beneficial for people with conditions marked by immune system dysfunction.

LDN represents the use of an established prescription medication in many other domains of medical treatment. Although many studies have shown promise with LDN therapy more studies are being conducted to investigate the effectiveness of LDN in treating a range of autoimmune illnesses. LDN is frequently used in conjunction with the traditional prescription medications typical for treating these various conditions with the exception of narcotics.

Side Effects?

LDN is known to be safe and well tolerated and this is one exciting aspect of LDN. The side effect profile is minimal with most common reports of vivid dreams and interrupted sleep during the initial adjustment they develop rapidly and decrease over time. LDN is compatible with most prescription medications except for narcotics. Low-dose naltrexone blocks the effects of narcotics and could cause withdrawal symptoms, so it should be started only after those drugs are completely out of your system.

Caution is taken with Hashimoto’s patients as LDN can lead to a prompt decrease in the autoimmune antibodies and may require a decrease in thyroid replacement medication as the body works more effectively.
