Vivitrol For Alcohol Addiction: Does Vivitrol Block Alcohol?

vivitrol for alcohol

In this article, we will discuss how using Vivitrol for alcohol disorders can help reduce the likelihood of relapse and end cravings. Vivitrol blocks alcohol-induced euphoria by plugging the brain’s opioid receptors.

The use of Vivitrol for alcohol addiction is similar to the Sinclair Method, except that Vivitrol is a long-acting shot that does not require a pill to be taken before every drinking session.

Patients typically receive the Vivitrol shot once per month.

We will now go deeper into the pharmacology of Vivitrol, research studies on Vivitrol, the pros and cons of Vivitrol vs oral naltrexone, and alternatives to Vivitrol for alcohol addiction.

How Vivitrol Blocks Alcohol

Vivitrol is a long-acting shot version of naltrexone hydrochloride, a generic medication that has been federally approved to treat both opiate and alcohol addiction.

Vivitrol is a opioid antagonist, meaning that it plugs the same brain receptors as opiates and endorphins (the brain’s natural pleasure chemicals). Instead of producing pleasurable effects, Vivitrol sits in the receptor site and simply blocks pleasure chemicals from entering.

Specifically, Vivitrol blocks the mu-opioid beta-receptor. You can see how this works in the picture below, which portrays the action of the Vivitrol shot.

When alcohol is consumed, the brain releases endorphins, which are endogenous opioids that are also released in response to exercise, food, sex, and other pleasurable activities.

Vivitrol therefore prevents drinkers from feeling pleasure when they drink. When oral naltrexone is consumed, it must be taken before every drinking session to be effective.

Vivitrol was approved for alcohol addiction in 2006 after research demonstrated that it reduced the amount of alcohol consumed and the severity of relapses.

There is some evidence that Vivitrol contributes to a higher likelihood of remaining abstinent. However, the mechanism through which Vivitrol works to extinguish alcohol cravings requires Vivitrol and alcohol to both be present, over the course of repeated episodes of drinking. This process is called pharmacological extinction.

Pharmacological Extinction

In other articles, I’ve partially explained alcohol addiction as an attempt to maintain comfortable levels of GABA, which is the brain’s primary calming neurotransmitter.

Yet as any heavy drinker knows, the calming effect of alcohol is only half of the equation. The other half is the profound sense of pleasure, euphoria, and reward that our brains come to associate with drinking.

For alcoholics, nothing releases endorphins as intensely as large quantities of alcohol.

In the past few decades, scientists have concluded that alcohol’s effects are mediated at least partly through the brain’s internal opioid system. This system is closely connected to the dopamine system, which is responsible for learning, motivation, and sense of reward.

From an evolutionary perspective, this makes sense: We need to remember things in our environment that give us pleasure so that we can instinctually seek them out in the future. For those of us who are predisposed to alcohol addiction, our brains’ attempts to automate goal-seeking for our own survival ends up threatening our survival.

The progression of alcoholic drinking can therefore be seen as a learned behavior even though the drinker has no conscious control over it. This kind of subconscious learning is reinforced by a chain reaction of neurotransmitters beginning with endorphins, which eventually causes the brain to release dopamine at the very idea of drinking. For an alcoholic in withdrawal, a single thought can easily begin the process of getting ready to go obtain alcohol from a store or a bar.

Pharmacological extinction is the gradual reversal of drinking as a learned behavior. Paradoxically, it is made possible only by drinking while on the Vivitrol shot or after taking oral naltrexone, allowing the drinker to stop feeling pleasure and euphoria from the act of drinking. Over time, the drinker’s internal opiate system and dopamine system rewire so that the thought of alcohol produces a state of indifference rather than craving.

In a sense, pharmacological extinction is the alcoholic equivalent of training Pavlov’s dogs to associate the bell with no food at all.

If a person with alcohol addiction stops getting the Vivitrol shot and continues to drink indefinitely, endorphins will be released that rekindle their alcohol addiction all over again.

Research Studies

vivitrol for alcohol

The use of Vivitrol for alcohol disorders shows promising results for alcoholism treatment:

  • In a 2005 double-blind, placebo-controlled study, the administration of 380 mg Vivitrol for alcohol dependent patients reduced episodes of heavy drinking and increased the likelihood of remaining abstinent (source)
  • A 1998 study found that a shot of long-acting naltrexone significantly reduced alcohol consumption for 20 alcohol-dependent subjects (source)
  • Out of 14 clinical trials conducted through 2001, only two failed to demonstrate the efficacy of naltrexone for alcohol disorders (source)
  • A 2014 meta-analysis found that naltrexone for alcohol disorders is effective at reducing heavy drinking and extinguishing cravings (source)

The last study points to a recurring theme on this site: Due to biochemical individuality, some treatment methods work better for some people than for others. With that said, the use of Vivitrol for alcohol addiction is one of the most effective treatments available.

Oral Naltrexone vs Vivitrol

The following considerations may be useful if you are trying to decide between taking oral naltrexone or using Vivitrol for alcohol addiction:

  • Convenience: A monthly shot of Vivitrol solves the problem of patient noncompliance, which accounts for the majority of failures in naltrexone studies.
  • Efficacy: Vivitrol and naltrexone have similar efficacy when compliance for the latter is taken into account
  • Cost: While oral naltrexone costs on average $11 per month, Vivitrol costs up to $1,100 per month. This cost differential is huge, although some patients do better on Vivitrol because it relieves them of the discipline required to take a pill.
  • Days Off Naltrexone: A benefit of naltrexone compared to Vivitrol is that once drinking is under control and no longer a daily habit, a user can take days off of the pill to enjoy exercise and other activities that stimulate endorphins.
  • Proponents of the Sinclair Method tend to have mixed opinions about oral naltrexone vs Vivitrol for alcohol disorders, with many preferring the former option.

While Vivitrol’s efficacy lasts for 2-4 weeks (usually closer to 4 weeks), the naltrexone pill exerts effects for a day or two, depending on the dosage.

Note: In severe cases as defined by high alcohol consumption, detoxification with medications may be necessary before introducing Vivitrol for alcohol addiction. Usually, 3-7 days of abstinence are recommended before treatment with Vivitrol. (source)

Before taking Vivitrol for alcohol addiction, be sure to review the following:

Alternative Treatment Methods

vivitrol for alcohol

Not everyone can obtain Vivitrol, since it must be prescribed by a doctor and injected by trained medical staff. Fortunately, more addiction treatment professionals have undergone training in how to administer Vivitrol in recent years.

While Vivitrol for alcohol addiction is a unique form of harm reduction, there are alternatives – including drugs that have been shown to be effective in controlling alcohol cravings when administered for long periods of time.

I will also briefly review some supplements and natural remedies that I REALLY wish I’d known about back when I was struggling with alcohol addiction.

Baclofen

Baclofen is a prescription drug that is structurally similar to GABA. Baclofen can be used to manage alcohol withdrawal symptoms, and it has also been used long-term by a growing number of people to achieve a state of indifference toward alcohol.

To learn more, check out my article on the interesting baclofen alcohol relationship.

Gabapentin

Gabapentin is similar to baclofen in that it helps the brain produce more GABA. It is increasingly popular for alcohol withdrawal, and sometimes combined with baclofen for long-term extinguishing of alcohol cravings.

You can read more about gabapentin in my article on this treatment method.

Kratom

Kratom is a plant that has been used for hundreds of years in Asia, and which contains compounds that are partial opioid agonists. An increasing number of people are successfully using kratom to get off of alcohol and manage cravings.

In my popular article about using kratom for alcohol withdrawal, I describe this method as the opposite of naltrexone.

I have made kratom tea on several occasions, with great results and no side effects. Of course, I take care and do not use kratom often. I promote the kratom from Top Extracts on this site because its kratom quality and customer service are second to none.

Phenibut

Phenibut is a legal supplement that is remarkably similar in structure to GABA. It is known to:

  • Calm the nervous system
  • Aid in sleep
  • Boost mood
  • Alleviate social anxiety

If you cannot obtain either gabapentin or baclofen, you can use phenibut to ease mild to moderate symptoms of alcohol withdrawal at home.

For a full description of how this might be done including dosage information, see my article on using phenibut for alcohol withdrawal.

Calm Support

Before I explain how Calm Support works, let me make one thing clear…

Nearly a year after I quit drinking, I finally understood that the majority of my post-acute withdrawal symptoms were caused by nutrient deficiencies caused by prolonged alcohol exposure.

I finally ended my post-acute withdrawal symptoms (including alcohol cravings) by doing a lot of research and spending a lot of money on herbs, vitamins, and minerals.

Calm Support is an ingenious collection of high quality nutrients and herbs that are very effective for alcohol withdrawal. These ingredients cost a lot of money when purchased separately. Many of my clients have been able to quit drinking using Calm Support along with external support and basic lifestyle improvements.

Conclusion

The use of Vivitrol for alcohol addiction is a little-known but highly effective treatment that can potentially save thousands of lives.

While not everyone responds well to Vivitrol, I believe that greater awareness of this pharmacological option can improve recovery odds for many people.

There is no one-size-fits-all approach for alcohol detox and recovery.

When I quit drinking, I had no idea what my alternatives for detox and recovery were. A doctor simply prescribed a course of benzodiazepines. I was not enlightened about other pharmacological options, nutrient repair, the hypoglycemic trap that so many recovering alcoholics fall into, or holistic strategies for improving my quality of life.

My goal in writing articles such as this one is to empower you to have a much better grasp on your situation, and your options, than I did when I quit drinking.
