Naltrexone does not produce a high; it blocks opioid receptors and prevents euphoric effects from drugs like heroin or morphine.
Understanding Naltrexone’s Pharmacology
Naltrexone is a medication primarily used to treat opioid and alcohol dependence. It functions as an opioid antagonist, meaning it binds to opioid receptors in the brain without activating them. This binding effectively blocks the receptors, preventing opioids from producing their typical effects, including euphoria or a “high.”
Unlike opioid agonists such as morphine or heroin that activate these receptors and cause pleasurable sensations, naltrexone’s role is to occupy the receptor sites without triggering any reward pathway. This mechanism is crucial in addiction treatment because it reduces cravings and the reinforcing effects of opioids.
Naltrexone also has applications in managing alcohol use disorder. While its exact mechanism in alcohol dependence is less direct, it is believed to modulate dopamine release associated with alcohol consumption, thus diminishing the rewarding feelings linked to drinking.
How Naltrexone Works in the Brain
The brain contains several types of opioid receptors: mu, kappa, and delta. The mu-opioid receptor is responsible for most of the pleasurable effects linked with opioids. Naltrexone has a strong affinity for these receptors but does not activate them. Instead, it competitively inhibits opioid molecules from binding.
Once naltrexone occupies these receptors, even if someone takes opioids afterward, those drugs cannot exert their effects. This blockade reduces or eliminates the risk of overdose and discourages drug use by removing the expected euphoria.
It’s important to note that because naltrexone blocks these receptors, it can precipitate withdrawal symptoms if taken by someone currently dependent on opioids. This happens because existing opioids are suddenly displaced from their receptor sites.
Can Naltrexone Get You High? The Science Behind It
No matter how much naltrexone you take, it will not cause a high or intoxication. Its chemical structure and pharmacodynamics do not allow it to stimulate the reward centers in the brain that are responsible for euphoria.
Some people might wonder if taking very high doses could somehow induce psychoactive effects. However, clinical studies and decades of medical use confirm that naltrexone lacks any intrinsic euphoric properties. Instead, its role is purely antagonistic.
In fact, naltrexone can blunt or block feelings of pleasure if opioids or alcohol are consumed during treatment. This makes it an effective deterrent against relapse but also explains why some patients may find the experience unpleasant if they continue using substances.
Naltrexone Versus Other Opioid Treatments
Comparing naltrexone to other medications used in opioid addiction treatment highlights its unique profile:
- Methadone: A full opioid agonist that activates receptors and can cause a high but is used therapeutically at controlled doses.
- Bupropion: Not an opioid but used for smoking cessation; it affects dopamine pathways differently.
- Bupernorphine: A partial agonist that produces mild opioid effects but with reduced risk compared to full agonists.
- Naltrexone: Pure antagonist with no euphoric effect; blocks all opioid activity.
This comparison clarifies that naltrexone’s lack of intoxicating effect is by design and therapeutic intent.
Side Effects and Misconceptions About Naltrexone
Though naltrexone does not get you high, some users report side effects such as nausea, headache, dizziness, or fatigue. These symptoms stem from its action on brain chemistry and are unrelated to any euphoric experience.
Misconceptions about naltrexone often arise from confusion with other drugs or anecdotal reports where patients felt “different” after starting treatment. However, feeling “different” does not equate to feeling “high.” The medication may alter mood slightly due to withdrawal relief or reduced cravings but never induces intoxication.
Another common myth involves combining naltrexone with opioids to achieve a stronger effect. In reality, this combination leads to blocked opioid activity and can cause severe withdrawal symptoms rather than any pleasurable sensation.
Why Some People Misinterpret Effects
The human brain reacts uniquely when dependent on substances suddenly loses access to those substances’ effects. Some might interpret relief from cravings or anxiety reduction as feeling “high,” but this is a psychological interpretation rather than a pharmacological effect of naltrexone.
Additionally, placebo effects can sometimes mislead individuals into thinking they experience subtle changes when taking medications like naltrexone. Clinical evidence shows no pharmacological basis for euphoria with this drug.
The Role of Naltrexone in Addiction Treatment Programs
Naltrexone plays a crucial role in comprehensive addiction management plans. It supports abstinence by blocking the rewarding effects of opioids and reducing relapse risk.
Treatment programs often combine medication with counseling or behavioral therapy for best outcomes. Patients on naltrexone must be fully detoxified from opioids before starting therapy because initiating while dependent can trigger severe withdrawal.
There are two main formulations:
- Oral tablets: Taken daily; requires strict adherence.
- Extended-release injectable (Vivitrol): Administered monthly; improves compliance.
Both forms maintain steady receptor blockade but differ in convenience and patient preference.
Effectiveness Compared With Other Medications
Studies show that while methadone and buprenorphine reduce illicit opioid use by activating receptors at lower levels, naltrexone works differently by preventing any activation at all.
This difference means some patients respond better to one medication over another depending on their history, preferences, and physiological response.
| Medication | Mechanism | Euphoric Potential |
|---|---|---|
| Methadone | Full agonist at mu-opioid receptor | High (dose-dependent) |
| Buprenorphine | Partial agonist at mu-opioid receptor | Mild (ceiling effect) |
| Naltrexone | Antagonist at mu-opioid receptor | None (blocks euphoria) |
This table highlights why naltrexone cannot get you high—it simply prevents other drugs from doing so.
The Risks of Misusing Naltrexone
While naltrexone itself doesn’t produce pleasurable effects, misuse or improper administration carries risks:
- Precipitated Withdrawal: Taking naltrexone too soon after using opioids causes sudden displacement of opioids from receptors leading to intense withdrawal symptoms.
- Liver Toxicity: High doses over time can strain liver function; monitoring is essential.
- Treatment Non-Adherence: Stopping medication abruptly may increase relapse risk.
Misunderstanding what naltrexone does may lead some individuals to misuse it hoping for a high or enhanced effect with other substances—this is dangerous and counterproductive.
The Importance of Medical Supervision
Starting naltrexone requires medical evaluation including liver function tests and ensuring complete detoxification from opioids. Healthcare providers tailor dosing schedules based on individual needs and monitor side effects closely.
Self-medicating or combining with illicit drugs increases risks dramatically without any benefit related to euphoria or intoxication.

Frequently Asked Questions
Can Naltrexone Get You High?
No, naltrexone does not produce a high. It blocks opioid receptors in the brain, preventing the euphoric effects that opioids like heroin or morphine cause. Its function is purely antagonistic and does not activate reward pathways.
Why Can’t Naltrexone Get You High Like Other Opioids?
Naltrexone binds to opioid receptors without activating them, unlike opioids that stimulate these receptors to create pleasurable sensations. This blockade stops opioids from producing a high, making naltrexone effective in addiction treatment.
Does Taking More Naltrexone Increase the Chance of Getting High?
Increasing the dose of naltrexone will not cause a high. Clinical studies show it lacks any euphoric or psychoactive effects, regardless of dosage. Its role is to block opioid effects, not mimic them.
Can Naltrexone Cause Any Psychoactive Effects if It Doesn’t Get You High?
Naltrexone does not cause intoxication or euphoria. While it may precipitate withdrawal symptoms in opioid-dependent individuals, it does not produce any psychoactive or rewarding sensations itself.
How Does Naltrexone’s Mechanism Prevent It From Getting You High?
Naltrexone competitively occupies opioid receptors without activating them, preventing other opioids from binding and triggering euphoria. This receptor blockade is why naltrexone cannot produce a high on its own.
Conclusion – Can Naltrexone Get You High?
The answer remains clear: naltrexone cannot get you high under any circumstances because it blocks opioid receptors instead of activating them. Its design purposefully eliminates euphoric effects associated with opioids and reduces alcohol-related reward sensations as well.
