Drinking During Vivitrol Treatment
Vivitrol® does not cause the alcohol reaction associated with Antabuse, but that does not make drinking safe. Its prescribing information says you should be able to stop drinking before treatment and should not be actively drinking when you receive your first injection.[1]
Vivitrol is the monthly injection of naltrexone used to treat alcohol dependence. It can help reduce heavy drinking as part of care that includes counseling or other support. It does not prevent alcohol withdrawal, and it can cause side effects, including nausea and vomiting.[1]
If you drink heavily or regularly, ask for medical advice before stopping. Withdrawal can cause seizures or severe confusion and may need monitored treatment. Call 911 for a seizure, severe confusion or another medical emergency.[2]
- Vivitrol is a monthly treatment that can reduce heavy drinking. It is used with counseling or other recovery support.[1]
- You should not be actively drinking when you receive the first injection. A prescriber should plan how you stop and assess withdrawal risk.[1][2]
- Vivitrol does not treat alcohol withdrawal. Withdrawal care is separate from medication used for ongoing recovery.[1][2]
- Tell your prescriber about opioid medicines and other opioid use before starting Vivitrol. Vivitrol can trigger severe opioid withdrawal, and trying to overcome its blocking effect can cause a fatal overdose.[1]
What Happens If You Drink on Vivitrol?
Vivitrol is not an alcohol deterrent like disulfiram (Antabuse). Its label states that drinking does not produce a disulfiram-like reaction.[1][3]
Nausea, vomiting and dizziness are among Vivitrol’s possible side effects. Their presence in the label does not mean alcohol caused them, and the absence of an Antabuse-like reaction does not rule them out. Tell your prescriber if you drink during treatment or develop symptoms so you can discuss what to do next.[1]
“Will it cause an Antabuse-like reaction?” and “Is drinking safe for me?” are different questions. Ask your prescriber about both.
Before treatment, ask: “If I drink after an injection, whom should I contact, and what symptoms need urgent care?” Having that answer gives you a next step if your plan becomes difficult. Do not use drinking as a test of whether the medication is working.
Do You Need to Stop Drinking Before the First Injection?
Yes. The Vivitrol label says to stop drinking before starting and not to be actively drinking at the first injection. It does not give one alcohol-free day count that establishes readiness for everyone. Your clinician should assess your drinking pattern, withdrawal history, health and other medicines.[1][2]
Advice about the tablet should not be treated as instructions for the injection. Clinical guidance allows oral naltrexone to begin while a person is still drinking, but the Vivitrol label has the specific starting instruction above. Ask about the exact form you are prescribed and how withdrawal will be managed.[1][4]
Vivitrol does not prevent or reduce alcohol withdrawal symptoms. If stopping has previously caused shaking, hallucinations or seizures, tell the clinician before trying again. A plan for alcohol withdrawal may be needed before the injection.[1][2]
Does Vivitrol Work for Alcohol?
Vivitrol is approved to treat alcohol dependence. In the injection study described in its label, outpatients received medication or placebo (an inactive comparison injection) plus psychosocial support, meaning help with behavior and recovery. Vivitrol reduced heavy-drinking days more than placebo. It is not a cure, and it may not work for everyone.[1]
A separate meta-analysis, which combines results from multiple studies, found that naltrexone reduced return to drinking and heavy drinking at about three months compared with placebo.[5]
Useful progress questions include: “Are cravings changing? Have heavy-drinking episodes changed? Are side effects or missed visits making treatment difficult?” Agree with your care team on what to track and when to review the plan. A return to drinking is something to discuss, not a reason to hide what happened.
How Vivitrol Helps with Drinking
Naltrexone is an opioid antagonist, which means it blocks opioid receptors, sites in the body where opioid substances act. The body’s own opioid chemicals may contribute to alcohol’s rewarding effects. The Vivitrol label says the exact brain mechanisms behind reduced drinking are not fully understood.[1]
You do not need to judge success by whether a drink feels different. Bring questions about cravings, drinking, side effects and support to your follow-up visit.
Research in controlled laboratory settings found that naltrexone reduced self-reported craving and the amount of alcohol consumed compared with placebo. Those studies used short medication schedules and artificial settings. They help explain possible treatment effects, but they cannot guarantee that each drink will feel less rewarding or that cravings will steadily disappear.[6]
Vivitrol Versus Antabuse for Drinking
The distinction is about how the medicines work, not punishment or willpower. Vivitrol blocks opioid receptors and can help reduce heavy drinking. Disulfiram blocks the breakdown of a substance produced when alcohol is processed, so drinking can cause a dangerous reaction.[1][3]

| Question | Vivitrol (naltrexone injection) | Antabuse (disulfiram) |
|---|---|---|
| What happens with alcohol? | Does not cause a disulfiram-like reaction.[1] | Can cause flushing, vomiting, chest symptoms and a rapid heartbeat. Severe reactions can be life-threatening.[3] |
| What must happen before starting? | Patients should not be actively drinking at the first injection. A clinician assesses readiness.[1] | The label requires stopping alcohol before starting. A clinician must assess suitability and explain alcohol avoidance.[3] |
| What is its role? | Can reduce heavy drinking with counseling or other recovery support.[1] | Acts as a deterrent to drinking because alcohol can trigger a reaction. It requires informed agreement.[3] |
Neither medicine is automatically the better choice. Discuss your drinking goals, health, other medicines and ability to follow the treatment plan.[7] For a broader comparison, see medications for alcohol use disorder.
Opioid Risks and Other Vivitrol Warnings
Never take more opioids to try to overcome Vivitrol’s blocking effect. This can cause a fatal overdose. People who previously used opioids may also be more sensitive to them after an injection is missed, near the end of a dosing interval or after treatment stops.[1]
Tell your prescriber about opioid pain medicines, tramadol, methadone, buprenorphine and nonprescribed opioids. Starting Vivitrol when you are physically dependent on opioids can trigger sudden, severe withdrawal. Do not stop prescribed opioid treatment on your own to get an injection. A clinician must plan the transition.[1]
Opioids are not the only safety concern. Vivitrol can cause serious injection-site reactions, liver problems and allergic reactions. Discuss concerning symptoms with a clinician. The label also calls for monitoring depression and suicidal thoughts.[1]
Tell medical and dental professionals that you receive Vivitrol, so they can plan pain treatment. Opioid pain treatment is not simply forbidden in every emergency, but if it is needed, the label requires specialized monitoring. Ask about access to an opioid overdose reversal medicine such as naloxone. Call 911 for a suspected overdose.[1]
Getting Help with a Vivitrol Treatment Plan
You can ask for help even if stopping has been difficult. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) explains that alcohol treatment includes medication, behavioral treatment and mutual support, and that primary care professionals can provide medication care. Ask which options fit your situation instead of assuming you must manage the change alone.[7]
- “How will we plan for stopping alcohol before the first injection?”
- “Do I need withdrawal treatment first?”
- “How do my opioid use, medicines and health conditions affect this choice?”
- “Who should I call if I drink, have side effects or need pain treatment?”
For the wider medication picture, read the Vivitrol guide, compare the oral naltrexone approach for alcohol, or learn about alcohol use disorder. Bring your questions and an accurate description of your drinking and medicine use to a prescribing appointment.
Ready to discuss medication and support? Find treatment help or compare alcohol treatment near you. Ask whether the provider offers medication assessment and follow-up.
If you are in crisis or thinking about suicide, call or text 988. For a medical emergency, call 911.[1][8]
Frequently asked questions
Can You Drink Alcohol on Vivitrol?
Vivitrol does not cause the disulfiram-like reaction associated with Antabuse, but that does not make drinking safe. Its label says to stop drinking before starting and not to be actively drinking at the first injection. If you drink during treatment, tell your care team and discuss the next step.[1]
Will You Get Sick If You Drink on Vivitrol?
Vivitrol does not cause an Antabuse-like alcohol reaction. It can still cause nausea, vomiting and other side effects, and that distinction is not a promise that drinking will be harmless. Symptoms should be discussed with a clinician rather than assumed to be either an alcohol reaction or proof that the medicine is working.[1]
Does Vivitrol Reduce Alcohol Cravings?
Naltrexone research has found reductions in craving and drinking in controlled settings, but responses vary. Those results do not guarantee that cravings will disappear after an injection. Vivitrol is used with counseling or other recovery support, and its label says it may not work for everyone.[1][6]
Do You Have to Be Sober to Start Vivitrol?
The Vivitrol label says to stop drinking before starting and not to be actively drinking at the first injection. A clinician should assess withdrawal risk and make a plan. Vivitrol does not treat alcohol withdrawal, and no single alcohol-free day count can establish that starting is appropriate for you.[1][2]
How Is Vivitrol Different from Antabuse for Alcohol?
Vivitrol blocks opioid receptors and can reduce heavy drinking. Disulfiram, known as Antabuse, causes an alcohol reaction that can be dangerous. Vivitrol does not cause that specific reaction, but both medicines require a suitability assessment and a clear plan before starting. Discuss disulfiram and alcohol avoidance with your clinician.[1][3]
Is Vivitrol an Effective Alcohol Treatment?
Vivitrol reduced heavy-drinking days compared with placebo (an inactive comparison injection) in the injection study described in its label, with counseling or other recovery support provided to participants. It is an approved treatment for alcohol dependence, but it is not a cure or a guarantee. Discuss expected benefits, side effects and follow-up with your prescriber.[1]
