How does Vivitrol work?
Vivitrol blocks receptors in the brain to prevent the brain from sending signals craving for drugs or alcohol and to block the positive (“high”) effects if opioids or alcohol are used.
Vivitrol is not a cure for addiction and does not help with detox, but does make staying sober easier.
Because Vivitrol blocks and doesn’t activate receptors in the brain, it is not addictive and doesn’t cause withdrawal symptoms if stopped.
What is in Vivitrol?
How does Vivitrol reduce cravings?
The fact that Vivitrol reduces cravings has been well-researched, but it’s not currently known exactly why.ⓘ
There are likely several chemical responses at play. For example, one study suggests that naltrexone may reduce cravings by elevating cortisol levels. Cortisol helps to control mood and motivation.ⓘ
However, psychology also plays a role. People are less likely to crave drugs or alcohol when they know they will not feel the positive effects.
What does Vivitrol block?
Vivitrol blocks opioid receptors in the brain. While alcohol doesn’t directly activate opioid receptors, research suggests a genetic variation in the mu-opioid receptor contributes to alcohol issues.ⓘ
Simulation of Vivitrol Blocking Opioids in the Brain
No, research shows Vivitrol does not reduce dopamine levels and is actually associated with a significant reduction of depression symptoms.ⓘ
Yes, endogenous opioids are opioids that are naturally produced by the body and are considered endorphins. (Opioid drugs are chemically similar to these endorphins). Vivitrol blocks these endorphins from attaching to the opioid receptors.ⓘ
Does Vivitrol help with pain?
Vivitrol isn’t a typical medication for pain relief.
Some studies show positive results of low-dose naltrexone for inflammatory and autoimmune conditions like fibromyalgia or multiple sclerosis. Though, these effects seem to be only at a low dose and are likely unrelated to the blocking of the opioid receptors. The research does not suggest that naltrexone is a good choice for a chronic pain patient addicted to opioid pain medications.ⓘ
Is Vivitrol addictive?
No, Vivitrol is not addictive and does not cause withdrawal symptoms when stopped.
It is overall well-tolerated with minimal side effects of Vivitrol and minimal drug interactions with Vivitrol.
Is Vivitrol considered a narcotic?
Vivitrol is not a narcotic, opioid or controlled substance. It doesn’t show on standard drug tests.
What are the alternatives to Vivitrol?

Does Vivitrol work?
Yes, study-after-study demonstrates that those who include Vivitrol in their treatment are more likely to stay sober. The evidence is clear that Vivitrol produces reduced drug and alcohol use and reduced cravings compared to placebo with rather limited side effects.ⓘ
What is Vivitrol's success rate?
The exact success rate number for Vivitrol depends on what study you look at and what counts as success.
- One year after starting Vivitrol for opioids, 64% of patients were opioid-free compared to 39% of the control group in non-comparative trials.ⓘ
- The first study on Vivitrol for alcohol showed a lower percentage of heavy drinking days (12% vs. 25% with the placebo).ⓘ In a follow-up 12-week Canadian study, 86% of patients were consuming less alcohol by their final visit.ⓘ
Is Vivitrol more effective than naltrexone?
Vivitrol is naltrexone given in the form of a monthly shot. Vivitrol would be just as effective as oral naltrexone if the pills were taken daily without missing or skipping a dose.
