1. What is Naltrexone and How Does It Work?
Naltrexone is a medication primarily used to manage alcohol and opioid use disorders. It functions as an opioid antagonist, which means it blocks the effects of opioids in the brain. Unlike some other medications for opioid use disorder, such as buprenorphine and methadone, naltrexone does not activate opioid receptors. Instead, it binds to them and prevents opioids from having their usual euphoric and sedative effects. This can help reduce cravings and make it less rewarding to use opioids or alcohol.
- Opioid Antagonist: Naltrexone blocks opioid receptors, preventing the effects of opioid drugs.
- Craving Reduction: It helps reduce cravings for both opioids and alcohol.
- Non-Addictive: Naltrexone itself has no abuse potential.
2. What are the Primary Uses of Naltrexone?
Naltrexone is FDA-approved for two primary uses: treating opioid use disorder and managing alcohol use disorder. In both cases, it is typically used as part of a comprehensive treatment plan that includes counseling and psychosocial support.
- Opioid Use Disorder: Naltrexone helps prevent relapse by blocking the effects of opioids.
- Alcohol Use Disorder: It can reduce cravings for alcohol and decrease the rewarding effects of drinking.
- Comprehensive Treatment: Naltrexone is most effective when combined with therapy and support groups.
3. How Effective is Naltrexone for Opioid Use Disorder?
Naltrexone can be highly effective for individuals with opioid use disorder who are committed to abstinence. By blocking the effects of opioids, it reduces the incentive to use and helps prevent relapse. However, it is important to note that naltrexone is most effective when taken consistently as prescribed and in conjunction with a comprehensive treatment program.
According to the Substance Abuse and Mental Health Services Administration (SAMHSA), naltrexone decreases reactivity to drug-conditioned cues and reduces cravings, aiding individuals in their recovery journey.

- Relapse Prevention: Naltrexone significantly reduces the risk of relapse in motivated individuals.
- Craving Management: It helps manage and reduce cravings for opioids.
- Adherence is Key: Consistent use and a comprehensive treatment plan are essential for success.
4. How Does Naltrexone Help with Alcohol Use Disorder?
For individuals with alcohol use disorder, naltrexone can help reduce cravings and decrease the pleasurable effects of alcohol. This can make it easier to cut back on drinking or abstain altogether. Naltrexone does not cause an adverse reaction when alcohol is consumed; instead, it diminishes the rewarding sensations associated with drinking, making it less appealing.
- Craving Reduction: Naltrexone helps reduce the intensity and frequency of alcohol cravings.
- Reduced Reward: It decreases the pleasurable effects of alcohol, making it less reinforcing.
- Combined Approach: Naltrexone works best when combined with counseling and support.
5. What are the Different Forms of Naltrexone Available?
Naltrexone is available in two main forms: oral tablets and an extended-release injectable suspension.
- Oral Naltrexone (ReVia, Depade): This form is taken daily as a pill. The typical dose is 50 mg once per day.
- Extended-Release Injectable Naltrexone (Vivitrol): This is an intramuscular injection given once a month (every 30 days). The dose is 380 mg.
The injectable form is often preferred because it eliminates the need for daily adherence, which can be a challenge for some individuals.
