Alcohol and Tramadol: what the published research says

PubMed indexes 7 records that name Alcohol and Tramadol 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.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Alcohol and Tramadol. 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.

The research

7 studies naming Alcohol and Tramadol.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Pharmacokinetics of tramadol and bioavailability of enteral tramadol formulations. 4th communication: drops (without ethanol).

Arzneimittel-Forschung · 2000 · PMID 10719611

Clinical Trial

“Rate and extent of the absolute bioavailability of tramadol in drops without ethanol were about the same as after administration of drops with ethanol. The results of this study gave no indication of a therapeutically relevant gender difference in the pharmacokinetics of tramadol.”

Lintz et al. · From the abstract

Names both Alcohol and Tramadol in its title.

Pharmacokinetics of tramadol and bioavailability of enteral tramadol formulations. 2nd communication: drops with ethanol.

Arzneimittel-Forschung · 1998 · PMID 9638309

Clinical TrialControlled Clinical Trial

“injection for the total distribution volume and the total and renal clearance were 216 +/- 21 l (Vd,beta), 487 +/- 71 ml/min (Cltot) and 77 +/- 20 ml/min (Clren), respectively. These results show that after administration of the drops (with ethanol) the active ingredient tramadol is rapidly absorbed and that the extent of the absolute bioavailability is about the same as after oral administration of tramadol capsules.”

Lintz et al. · From the abstract

Names both Alcohol and Tramadol in its title.

CYP24A1 and CYP3A4 Levels, Renal, Hepatic Changes, and Incidence of Oxidative Stress in Tramadol-Alcohol Concomitant Misuse.

Cureus · 2023 · PMID 37123794

“In this study 77.4% of participants reported euphoria as reason for combining Alcohol and Tramadol, 6.5% claimed it was for faster pain relief and enhanced sexual performance or prolong penile erection was the response of 58.1% of the test participants. Findings of reduced CYP3A4 with Alcohol and Tramadol concomitant use could be associated with delayed drug inactivation and increased drug euphoric action.”

Dic-Ijiewere et al. · From the abstract

Names both Alcohol and Tramadol in its title.

Pharmacokinetic changes of tramadol in rats with hepatotoxicity induced by ethanol and acetaminophen in perfused rat liver model.

Alcohol (Fayetteville, N.Y.) · 2019 · PMID 30248395

Animal study

“Liver damage caused by ethanol and acetaminophen during 45 days in animals leads to a significant reduction in the level of tramadol metabolites. Therefore, in patients with liver damage caused by ethanol and acetaminophen, caution needs to be considered when prescribing tramadol.”

Mohammadi et al. · From the abstract

Names both Alcohol and Tramadol in its title.

Oral hydromorphone extended-release.

The Consultant pharmacist : the journal of the American Society of Consultant Pharmacists · 2010 · PMID 21172762

Comparative StudyReviewHuman subjects

“Hydromorphone ER is the newest oral opioid to enter a crowded marketplace now totaling 15 different Schedule 2 opioids (including tapentadol), and tramadol, available in oral, parenteral, rectal, transdermal, transmucosal, and intranasal formulations. It does not appear to have any unique assets or liabilities and should be considered as one of many oral opioids available for the management of persistent pain of moderate-to-severe intensity.”

Guay · Authors' conclusion

Names Alcohol and Tramadol together in an interaction, co-administration, or pharmacokinetic context.

Lethal combination of tramadol and multiple drugs affecting serotonin.

The American journal of forensic medicine and pathology · 2000 · PMID 11111800

Case ReportsReviewHuman subjects

“The data in Adverse Event Reporting System of the Food and Drug Administration from November 1, 1997 to September 8, 1999 was reviewed along with a MEDLINE search from 1966 to the present. This case appears to be the first reported death caused by seizure activity in a patient taking tramadol in combination with drugs that affect serotonin.”

Ripple et al. · From the abstract

Names Alcohol and Tramadol 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:

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, Tramadol, 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.
