What Is Naltrexone?

Naltrexone is a medication approved by the Food and Drug Administration (FDA) to treat both alcohol use disorder (AUD) and opioid use disorder (OUD). It is viewed as a medication-assisted treatment option. Naltrexone can be prescribed and administered by a practitioner that is licensed to prescribe medications. It is available as an extended-release intramuscular injectable for alcohol and opioid use disorder. And it is available in a pill form for alcohol use disorder. REMS, also known as a risk evaluation and mitigation strategy is required for the long-acting injectable formulation. This is to ensure that the benefits of the drug far outweigh the risks. Naltrexone is taken daily and the extended-release injectable can be administered by a practitioner every four weeks, or once a month. It is usually ReVia or Depade and it can be taken at 50 mg once per day. The injectable extended form of Naltrexone is Vivitrol and it’s administered at 380 mg intramuscular once a month. Naltrexone is considered one of the elements of a comprehensive treatment plan, that includes counseling and other behavioral approaches to provide patients with a whole-person approach. It’s not recommended as a MAT option for anyone younger than 18 years of age, or patients experiencing various other health options. Naltrexone is not addictive, is not an opioid, and doesn’t cause withdrawal symptoms without stopping use. It blocks the sedative and europhic effects of opioids such as morphine, codeine, and heroin. Naltrexone blocks and binds opioid receptors, yet it also suppresses and reduces opioid symptoms and cravings. There is no diversion potential or abuse with Naltrexone.

Naltrexone for Opioid Use Disorder

To reduce the risk of withdrawal symptoms that are caused by OUD, patients should wait for at least 7 days after their last use of short-acting opioids. Furthermore, they should wait 10 to 14 days for long-acting opioids, before beginning Naltrexone. When patients are engaging in Naltrexone, they should not engage in any of the following:

Opioids or illicit drugs

Take sedatives

Other drugs

Patients should notify their practitioner about all the medications they are taking and medication changes while being treated for Naltrexone. Even though the oral formulation blocks the opioid receptors, the long-acting injectable formulation in MAT is FDA approved and requires REMS. The patients on Naltrexone who relapse after an abstinence period or who discontinue use might have a reduced opioid tolerance. Therefore, engaging in lower dosages or taking the same amount of opioids used in the past can cause dangerous consequences.

Naltrexone for Alcohol Use Disorder

Upon starting Naltrexone for AUD, patients shouldn’t be physically dependent on alcohol or other substances. To avoid strong side effects such as nausea and vomiting, practitioners generally wait until after the detox process has passed before administering Naltrexone. Naltrexone binds to the endorphin receptors in an individual’s body and blocks the feelings and effects of alcohol. It reduces alcohol cravings and the amount of alcohol consumed. Once a patient stops engaging in alcohol use, taking Naltrexone assists in maintaining during recovery. The Naltrexone MAT Treatment will last for three to four months. The practitioners should continue monitoring the patients who are no longer taking Naltrexone.
