Alcohol and Pregabalin: what the published research says
PubMed indexes 8 records that name Alcohol and Pregabalin 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 Pregabalin. 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 Pregabalin.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Pregabalin, within a dosage of 150-450 mg/day, showed beneficial effects for alcohol relapse prevention and contrasting results for the treatment of the withdrawal syndrome. Its use appears to be safe and well tolerated.”
“Pregabalin shows promise as a treatment for alcohol dependence. Although limited by a low number of participants and by the open design, this is the first study concerning the efficacy and safety of pregabalin in current alcoholics. In these patients pregabalin was effective and well tolerated. Additional research is needed to explore the clinical relevance of these findings.”

Human subjects
“Mean proportion of HDD significantly decreased on average by 48.7% (SD = 35.1%; median (IQR) = 57.1% (14.3% to 78.6%)). The proportion of abstinent days increased significantly on average by 36.1% (SD = 35.0%; median (IQR) = 17.9% (14.3% to 75.0%); S = 49.5, p = .0005).Conclusions: Pregabalin treatment of AUD appears to be safe and well tolerated in doses up to 600 mg per day.Trial Registration: clinicaltrials.gov identifier: NCT03256253.”

“These data suggest that oxycodone-induced tolerance is mediated by PKC and that reversal of tolerance by ethanol or pregabalin may be a contributory factor in oxycodone overdose deaths.”
“However, the current evidence is promising and provides a platform for future studies, including appropriate randomized, placebo- and/or comparator-controlled studies, to further explore the efficacy and safety of pregabalin for the treatment of withdrawal symptoms. Given the potential for pregabalin misuse or abuse, particularly in individuals with a previous history of substance abuse, clinicians should exercise caution when using pregabalin in this patient population.”

“Clinicians should be cautious in prescribing pregabalin to patients with a history of multiple substance recreational use, and monitor its effects on cognition at dosages above 450 mg/d. Further, well-designed clinical research is still needed for the eventual consolidation of pregabalin's place in the treatment of AD and BD.”
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.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Alcohol, Pregabalin, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
