Alcohol and Methylphenidate: what the published research says
PubMed indexes 8 records that name Alcohol and Methylphenidate 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 Methylphenidate. 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 Methylphenidate.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
Journal of clinical psychopharmacology · 2017 · PMID 28590363
Randomized Controlled Trial
“These findings support drug dispositional interactions between ethanol and MPH as dominant over potential biopharmaceutical considerations. Understanding the pharmacology underlying the frequent coabuse of MPH-ethanol provides rational guidance in the selection of first-line pharmacotherapy for comorbid attention-deficit/hyperactivity disorder-alcohol use disorder.”
Names both Alcohol and Methylphenidate in its title.
Journal of clinical psychopharmacology · 1999 · PMID 10440465
Case ReportsHuman subjects
“Amounts of ethylphenidate detected in whole blood specimens in these two cases (8 ng/mL and 1 ng/mL, respectively) were small relative to methylphenidate and ritalinic acid concentrations. Nonetheless, given the high likelihood that methylphenidate and ethanol coingestion frequently occurs, the detection of ethylphenidate in humans warrants further investigation into the extent of its formation as well as into any associated toxicity in nonoverdose situations.”
Names both Alcohol and Methylphenidate in its title.
Journal of studies on alcohol and drugs · 2026 · PMID 42504879
“The findings of this study showed that HIIT intervention could be associated with significant reduction in adverse effects of concurrent consumption of MPD and ethanol on oxidative stress, mitochondrial fission and mitophagy, and injury in heart of healthy male rats.”
Names both Alcohol and Methylphenidate in its title.
“Both ethanol and MPD produced hypothermia. Some of these results might help explain why users take MPD and ethanol in combination in order to enable consuming larger amounts of alcohol.”
Names both Alcohol and Methylphenidate in its title.
Pharmacology, biochemistry, and behavior · 2016 · PMID 27794433
Animal study
“These data indicate increased impairment of memory function with combined MPH and EtOH use. By understanding how the combination of methylphenidate and alcohol affects memory, we can better assess the risks of taking both substances simultaneously.”
Names both Alcohol and Methylphenidate in its title.
Journal of pharmaceutical sciences · 2014 · PMID 25303048
Research Support, N.I.H., ExtramuralReviewHuman subjects
“C57BL/6 mice model dl-MPH-ethanol interactions: an otherwise depressive dose of ethanol synergistically increases dl-MPH stimulation; a substimulatory dose of dl-MPH potentiates a low, stimulatory dose of ethanol; ethanol elevates blood, brain, and urinary d-MPH concentrations while forming l-EPH.”
Names both Alcohol and Methylphenidate 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.

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, Methylphenidate, 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.
