Can You Drink Alcohol on Naltrexone?

Yes — and unlike Antabuse, nothing dramatic happens. That is the point.

You can drink on naltrexone, and nothing violent happens if you do. This is the single most common point of confusion, and it comes from conflating naltrexone with disulfiram (Antabuse), which is a genuinely different medication.

Naltrexone is not Antabuse

Disulfiram works by deterrence: it blocks alcohol metabolism, so drinking causes flushing, nausea, vomiting and a racing heart. It is designed to make drinking punishing.

Naltrexone does nothing of the kind. It blunts the reward rather than adding a punishment. If you drink on naltrexone, the most likely experience is that the drink is less satisfying than you expected — and that the pull toward the next one is weaker.

Why some approaches involve drinking on it deliberately

Because the reward pathway is being blocked while drinking occurs, the learned association between alcohol and reward can weaken over time. Some treatment approaches use this deliberately rather than requiring abstinence first. Whether that suits you is a clinical conversation, and it depends on your goal and history.

What this does not mean

Naltrexone reduces the reward from alcohol. It does not reduce alcohol's other effects: it does not make you less impaired, less likely to be over the legal limit, or protect your liver. Intoxication and its risks are unchanged.

If you drink daily or heavily Stopping suddenly after sustained heavy drinking can cause withdrawal that is medically serious — shaking, sweating, a racing heart, confusion, or seizures. Do not stop on your own to "get ready" for treatment. Tell a provider how much and how often you drink; that shapes how treatment is started safely. If you are in medical distress, call 911.
Safety check Naltrexone is not safe to combine with opioids, including prescription pain medication. A provider screens for this and other contraindications during evaluation. Individual results vary, and naltrexone is not a substitute for emergency or detox care.

Talk it through with a provider

A 45–60 minute video evaluation with a board-certified psychiatric provider. Same-week appointments are typical.

Common questions

No. That reaction is associated with disulfiram (Antabuse), a different medication. Naltrexone reduces how rewarding alcohol feels rather than causing a physical punishment.

No. It blunts the rewarding sensation but does not reduce impairment. You can still be intoxicated and all the usual risks of drinking still apply.

Naltrexone does not create a dangerous interaction with alcohol the way some medications do. That is not the same as drinking being safe in general — discuss your drinking pattern and any liver concerns with your provider.
