What is naltrexone?

Naltrexone is an opioid antagonist, typically used to help patients with opioid use disorder or alcohol use disorder. It works by blocking opioid receptors. This blocks the euphoric and sedative effects of opioids, as well as cravings the patient may have for opioids.

Why use low dose naltrexone for pain?

Naltrexone used at low doses is thought to reduce inflammation and relieve chronic pain. There is no abuse and diversion potential. Even though the mechanism in which how it works to treat pain is unknown, it is thought that by blocking the opioid receptors, your body compensates by producing more endogenous opioids.

Who would benefit from low dose naltrexone use?

Most of the evidence for low dose naltrexone use shows that there may be benefit in patients with inflammatory bowel disease, diabetic neuropathy, fibromyalgia, multiple sclerosis, and complex regional pain syndrome. Use may also be useful in those with a history of opioid use disorder, or for those at higher risk of becoming addicted to opioids.
