Alcohol and Ketamine: what the published research says
PubMed indexes 8 records that name Alcohol and Ketamine together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Alcohol and Ketamine. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
8 studies naming Alcohol and Ketamine.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
The American journal of drug and alcohol abuse · 2025 · PMID 40773768
Systematic ReviewHuman subjects605 participants
“While promising, considerable variability in dosing, therapeutic approaches, and study designs limits the certainty of evidence. Future research examining the long-term safety and efficacy of ketamine is needed.”
Journal of affective disorders · 2024 · PMID 39214377
Randomized Controlled Trial
“IN ketamine appears to induce rapid anti-fatigue effects in individuals with severe MDD and BDep both with and without comorbid AUD. This suggests that IN ketamine holds potential as an alternative, rapid-acting, anti-fatigue option for different medical conditions.”
The American journal of psychiatry · 2022 · PMID 35012326
Randomized Controlled Trial
“This study demonstrated that treatment with three infusions of ketamine was well tolerated in patients with alcohol use disorder and was associated with more days of abstinence from alcohol at 6-month follow-up. The findings suggest a possible beneficial effect of adding psychological therapy alongside ketamine treatment.”
Neuropsychopharmacology : official publication of the American College of Neuropsychopharmacology · 2025 · PMID 40021941
Animal study
“Notably, R-ketamine demonstrated a lasting reduction in alcohol consumption without adverse effects. In conclusion, our preRCT demonstrates R-ketamine's effectiveness in reducing alcohol relapse and supports translation to a clinical RCT that accounts for sex-dependent effects.”
“Ketamine may be an effective therapeutic modality for people with alcohol use disorders who fail to respond to FDA-approved first-line agents. More robust clinical trials are necessary to provide a more accurate assessment of efficacy, safety profile, and dosing strategies for ketamine utilization in alcohol use disorder.”
Neuroscience and biobehavioral reviews · 2021 · PMID 33989669
ReviewHuman subjects
“Ketamine's effect in treating depression and stress disorders, such as PTSD, and preliminary evidence for treating SUDs further suggests a role for treating AUDs. This review explores the behavioral and neural evidence for treating AUDs with ketamine and clinical data on ketamine therapy for AUDs and SUDs.”
“In essence, there are striking similarities between ketamine and alcohol particularly in terms of modulating glutamatergic and dopaminergic signaling in cortico-limbic brain areas involved in learning, reward and mood regulation, thereby, probably mediating both, AR as well as the development of addiction. Moreover, moderate amounts of both drugs have comparable immunoinhibitory effects hypothesized to be involved in AR, too.”
Names both Alcohol and Ketamine in its title.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.
