Naltrexone reduces alcohol’s pleasurable effects, making it harder to get drunk but not impossible.
How Naltrexone Works and Its Impact on Alcohol Intoxication
Naltrexone is a medication primarily prescribed to help people reduce or stop drinking alcohol. It works by blocking opioid receptors in the brain, which play a role in the brain’s reward system. When you drink alcohol, your brain releases endorphins that bind to these receptors, producing feelings of pleasure and euphoria. Naltrexone essentially cuts off this pathway, dulling the rewarding effects of alcohol.
Because of this mechanism, naltrexone doesn’t prevent you from drinking or absorbing alcohol into your bloodstream. Instead, it lowers the “high” or buzz you might get from drinking, which can reduce cravings and discourage excessive consumption. However, this doesn’t mean it makes you immune to intoxication.
The Difference Between Intoxication and Reward
Alcohol intoxication involves a combination of factors: blood alcohol concentration (BAC), how fast you drink, your body weight, metabolism, and tolerance. Naltrexone doesn’t directly alter BAC or how your liver processes alcohol. Instead, it affects how your brain perceives the effects of alcohol.
You can still become physically impaired or drunk while on naltrexone because the drug doesn’t block all pathways related to intoxication. For example, alcohol’s depressant effects on motor skills and judgment remain intact. The difference is that the euphoric feeling—often what people chase when drinking—is significantly blunted.
Can You Get Drunk If You’re On Naltrexone? The Science Behind It
The short answer is yes—you can get drunk while taking naltrexone—but it’s less likely you’ll experience the same level of pleasure from drinking that often leads to heavy or binge drinking episodes.
Research shows that people on naltrexone tend to drink less because they don’t get as much enjoyment from alcohol. This reduction in pleasure helps break the cycle of addiction for many individuals. Still, if someone drinks enough alcohol quickly enough, they will feel intoxicated due to the direct effects of alcohol on their body.
Clinical Studies and Real-World Outcomes
Several clinical trials have demonstrated naltrexone’s effectiveness in reducing heavy drinking days and increasing abstinence rates among people with alcohol use disorder (AUD). These studies also highlight that while naltrexone reduces cravings and satisfaction from drinking, it does not eliminate intoxication risk entirely.
For instance:
- Participants reported less “high” or euphoria when drinking.
- They drank fewer drinks per occasion.
- Binge drinking episodes were less frequent but still possible.
This means naltrexone acts more like a dampener than a shield against intoxication.
Understanding Alcohol Tolerance vs. Naltrexone Effects
Some people confuse tolerance with medication effects. Tolerance develops when repeated exposure to alcohol causes your brain to require more to feel drunk. Naltrexone does not increase tolerance; rather, it blocks opioid receptors temporarily to reduce pleasure.
If you have high tolerance due to long-term drinking habits, you might still get drunk on naltrexone but with diminished reward sensations. This distinction is crucial because feeling impaired without feeling rewarded can be frustrating and potentially dangerous if someone drinks excessively trying to chase a buzz that won’t come.
The Role of Dosage in Getting Drunk While on Naltrexone
Naltrexone is typically prescribed at doses ranging from 25 mg to 50 mg daily for AUD treatment. The standard dose effectively blocks opioid receptors but doesn’t create an impenetrable barrier against intoxication.
Some patients may be tempted to drink more while on naltrexone because they don’t feel as good after fewer drinks. This behavior can increase BAC rapidly and cause physical impairment despite lowered enjoyment levels.
Side Effects and Risks of Drinking Alcohol While Taking Naltrexone
Mixing alcohol with any medication requires caution. Although naltrexone is designed for use alongside efforts to reduce or quit drinking, there are important safety considerations:
- Liver strain: Both naltrexone and alcohol metabolize through the liver; excessive intake can increase liver damage risk.
- Nausea and dizziness: Common side effects of naltrexone may worsen with concurrent heavy drinking.
- Reduced judgment: Even if pleasure is blunted by naltrexone, physical impairments remain; this increases accident risks.
If someone ignores medical advice and drinks heavily while taking naltrexone, they may still experience harmful consequences associated with intoxication.
Alcohol Consumption Patterns With Naltrexone Treatment
People on naltrexone often show changes in their drinking habits:
| Pattern | Description | Effect with Naltrexone |
|---|---|---|
| Heavy/Binge Drinking | Consuming large amounts quickly leading to high BAC. | Reduced frequency but still possible; less rewarding sensation. |
| Moderate Drinking | Lower quantities spread out over time. | Easier to maintain abstinence or low consumption due to blunted reward. |
| Total Abstinence | No consumption at all. | Naltrexone supports cravings reduction; often combined with therapy. |
This table summarizes how different levels of drinking respond under naltrexone treatment.
The Danger of “Chasing the Buzz” While on Naltrexone
Some individuals try consuming more alcohol hoping for stronger effects since initial drinks offer less pleasure on naltrexone. This behavior risks rapid intoxication without enhanced reward—leading to potential overdoses or accidents.
Healthcare providers caution patients about this possibility because it undermines treatment goals and increases health risks.
Naltrexone vs Other Medications for Alcohol Dependence: A Quick Comparison
Naltrexone isn’t the only FDA-approved drug for AUD; others include acamprosate and disulfiram. Each works differently:
| Medication | Main Mechanism | Effect on Intoxication & Reward |
|---|---|---|
| Naltrexone | Opioid receptor antagonist blocking pleasure signals. | Dampens euphoria; does not prevent intoxication. |
| Acamprosate | Modulates glutamate/GABA balance reducing cravings post-abstinence. | No direct effect on intoxication; supports relapse prevention. |
| Disulfiram (Antabuse) | Blocks aldehyde dehydrogenase causing unpleasant reaction if alcohol consumed. | Makes drinking physically uncomfortable; no effect on intoxication itself. |
Understanding these differences helps clarify why naltrexone allows intoxication but reduces its rewarding aspects uniquely compared to other options.
The Importance of Medical Supervision When Using Naltrexone With Alcohol Use Disorder
Naltrexone should always be taken under medical supervision with clear guidance about safe behaviors around alcohol consumption. Doctors usually recommend:
- Avoiding heavy drinking during treatment periods.
- Mental health counseling alongside medication for best results.
- Liver function monitoring before and during therapy due to potential toxicity risks.
- Avoiding opioids completely since naltrexone blocks their pain-relief effects (can cause withdrawal).
- Cautious use if pregnant or breastfeeding—naltrexone safety data varies here.
Ignoring professional advice can lead not only to reduced effectiveness but also dangerous health consequences.

Frequently Asked Questions
Can You Get Drunk If You’re On Naltrexone?
Yes, you can still get drunk while taking naltrexone. The medication reduces the pleasurable effects of alcohol but does not prevent alcohol from entering your bloodstream or impairing your motor skills and judgment.
This means intoxication is possible, though the euphoric feeling that often encourages heavy drinking is significantly diminished.
How Does Naltrexone Affect Your Ability to Get Drunk?
Naltrexone blocks opioid receptors in the brain, reducing the rewarding sensations caused by alcohol. While it lowers the “high” or buzz, it does not change blood alcohol concentration or how your body metabolizes alcohol.
You can still experience physical impairment and intoxication despite the blunted pleasure response.
Why Might You Drink Less If You Can Still Get Drunk on Naltrexone?
Because naltrexone diminishes the pleasurable effects of alcohol, many people find drinking less satisfying. This reduction in enjoyment helps decrease cravings and discourages excessive or binge drinking.
Even though intoxication remains possible, the motivation to drink heavily often lessens.
Does Naltrexone Prevent Alcohol-Related Impairment?
No, naltrexone does not prevent alcohol’s depressant effects on motor skills, coordination, or judgment. You can still be physically impaired or drunk while on the medication.
The drug primarily targets the brain’s reward system rather than the direct intoxicating effects of alcohol.
What Should You Know About Getting Drunk While Taking Naltrexone?
If you drink enough alcohol quickly, intoxication will occur regardless of naltrexone use. The medication helps reduce cravings and pleasure but does not make you immune to alcohol’s effects or risks associated with drinking.
It’s important to use naltrexone as part of a comprehensive treatment plan for alcohol use disorder under medical supervision.
The Bottom Line: Can You Get Drunk If You’re On Naltrexone?
Yes—you definitely can get drunk while taking naltrexone because it doesn’t stop your body from absorbing or processing alcohol nor does it block all intoxicating pathways.
What changes is how your brain responds emotionally—the pleasurable buzz fades away significantly making heavy drinking less appealing.
However, physical impairment remains just as real as ever.
This means you need extra caution because you might underestimate how impaired you are without feeling “drunk” in the usual sense.
Naltrexone is a powerful tool in fighting alcohol dependence but isn’t a magic shield against getting drunk.
Proper use combined with counseling offers the best chance at long-term success.
