Vivitrol for alcohol is a non-narcotic, non-addictive shot for alcoholism. It’s  medication used in combination with counseling to treat opiate and alcohol dependence and prevent a relapse after detoxification.

Vivitrol injection is used to prevent relapse in adults who became dependent on opioid medicine and then stopped using it. Naltrexone can help keep you from feeling a “need” to use the opioid.

Along with a comprehensive recovery program and psycho-social support, such as counseling and self-help groups, the Vivitrol shot (Naltrexone IM) has been shown to be effective in reducing alcohol consumption and blocking the effects of opiates while reducing cravings, keeping patients engaged in treatment, and assisting in sobriety.

Why Vivitrol is used for addiction recovery

Vivitrol is a medication that is used to treat addiction to opioids and alcohol. It contains the active ingredient naltrexone, which is an opioid antagonist. This means that it blocks the effects of opioids and alcohol on the brain, reducing the cravings and the pleasurable effects of these substances.

One of the benefits of Vivitrol is that it is administered by injection once a month, which can improve medication adherence and reduce the risk of relapse. The injection also eliminates the need for daily medication, which can be a burden for some patients.

Another benefit of Vivitrol is that it has been shown to be effective in reducing cravings and preventing relapse in patients with opioid and alcohol dependence. Clinical studies have demonstrated that Vivitrol can reduce the risk of relapse by 55% in patients with opioid addiction and by 17% in patients with alcohol addiction.

Vivitrol can also help with other aspects of addiction recovery, such as reducing the risk of overdose and improving mental health. It has been shown to reduce the risk of overdose in patients with opioid addiction, and can improve depression and anxiety symptoms in patients with alcohol addiction.

Overall, Vivitrol can be a valuable tool in addiction recovery, particularly for patients who have struggled with relapse or have difficulty adhering to daily medication. However, it is important to note that medication should always be used as part of a comprehensive treatment plan that includes therapy, support groups, and other forms of treatment.

Alcohol Dependence

Vivitrol has been demonstrated to have the following effects:
  • Vivitrol for alcohol reduced heavy drinking days by 92% in patients who were able to abstain for 7 days.
  • Patients treated with a Vivitrol shot demonstrated a greater reduction in days of heavy drinking than those treated with a placebo.

Vivitrol for Alcohol Addiction

Initially, Vivitrol was approved by the Food and Drug Administration in 2006 to prevent relapse in those recovering from an alcohol use disorder. Naltrexone works to minimize cravings for alcohol via a different mechanism than previously used alcohol relapse prevention medicines, like disulfiram, which discourages continued drinking by making those in recovery sick if they consumed alcohol.

Vivitrol has been effective in augmenting recovery from addiction to alcohol. In a six-month double-blind study, people who used Vivitrol with counseling to treat an alcohol use disorder experienced a 25 percent greater reduction in the number of heavy drinking days after they graduated from treatment. Overall, people whose alcohol use disorder was treated with both Vivitrol and rehabilitation counseling spent more time abstinent from alcohol and had lower rates of relapse.

Naltrexone’s theorized mechanism of action stems from the fact that intoxicating substances like alcohol release endorphins, making the person feel good. This reinforces, in classic Pavlovian fashion, the want and then the need to drink more to feel good. In people being treated for alcohol use disorders, Vivitrol, an opioid receptor antagonist, blocks the endorphins from binding to their receptors, thereby ending the good feeling associated with being drunk. There may be some other signs of intoxication, but the pleasure of drinking will be greatly diminished. Among people who relapse into old patterns of alcohol use, the drive to drink should gradually disappear since it no longer offers perceived benefits.

Opioid Dependence

Vivitrol has been demonstrated in a six-month, placebo-controlled trial to have the following effects:
  • 90% remained opiate free versus 35% for placebo
  • 50% decrease in craving for opiates from baseline 
  • 53% completed 24-week treatment program versus 38% completion without Vivitrol
  •  Maintained 168 days in treatment for Vivitrol versus 96 days for placebo
  •  Less than 1% relapsed into dependence versus 14% for placebo


The team at INSynergy has helped many people turn their back on addiction and start a fresh, new life.

Dr. Taca was voted one of the Best Doctors of America in Psychiatry and Addiction Medicine, and developed the Vivitrol program for those who are motivated to beat addiction and leave it behind forever.
