Alcohol and Amitriptyline: what the published research says
PubMed indexes 8 records that name Alcohol and Amitriptyline 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 Amitriptyline. 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 Amitriptyline.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“There were few differences between drugs after alcohol but with some measures the interaction with amitriptyline was subjective rather than additive or potentiating. This reflected the already substantial effects of amitriptyline alone.”
Names both Alcohol and Amitriptyline in its title.
“In combination with either trazodone or amitriptyline, ethanol caused little additional effect except in the case of manual dexterity which was further impaired. This result may reflect the profound effects of the antidepressants alone and does not suggest that it is safe for patients receiving antidepressant medication to take ethanolic drinks.”
Names both Alcohol and Amitriptyline in its title.
“The combination of amitriptyline and ethanol results in a particularly marked increase in body sway. No sedative nor alerting effect of zimelidine was seen, nor was any interaction between zimelidine and ethanol apparent.”
Names both Alcohol and Amitriptyline in its title.
Research Support, N.I.H., ExtramuralHuman subjects
“For amitriptyline, the data suggest inhibitory effects of CYP1A2 and CYP2A6. Our results demonstrate the importance of functional interactions between multiple P450 species and their decisive role in the effects of alcohol exposure on drug metabolism.”
Names both Alcohol and Amitriptyline in its title.
European journal of clinical pharmacology · 1983 · PMID 6628520
Human subjects
“Ethanol increases free amitriptyline plasma concentrations most dramatically during the period of drug absorption; this is due to a decrease in amitriptyline hepatic clearance, resulting in decreased first-pass extraction. Together with the pharmacodynamic interaction, the kinetic changes provide a rationale for the toxicity of this combination and its deleterious effects on psychomotor skills.”
Names both Alcohol and Amitriptyline in its title.
“Another study of the acute and chronic effects of moclobemide (200 mg 3 times daily) or clomipramine (25 mg twice daily) and their interactions with alcohol (blood alcohol concentration 0.6 g/l) showed that alcohol caused significant impairment, whereas clomipramine tended to enhance and moclobemide to reduce some impairment. Moclobemide appears to be an antidepressant with few psychomotor effects and minimal alcohol potentiation and may reduce some alcohol impairment.”
Names Alcohol and Amitriptyline together in an interaction, co-administration, or pharmacokinetic context.
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, Amitriptyline, 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.
