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