Alcohol and Lorazepam: what the published research says

PubMed indexes 4 records that name Alcohol and Lorazepam 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.

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 Lorazepam. 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.

4 studies naming Alcohol and Lorazepam.

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

Effect of short-term ethanol administration on lorazepam clearance.

Hepatology (Baltimore, Md.) · 1981 · PMID 6116659

“In dogs and man, ethanol did not significantly alter lorazepam t1/2, plasma protein binding, or distribution volume (Vd beta). The results suggest that short-term ethanol administration impairs the conjugation of lorazepam in dogs and man.”

Hoyumpa et al. · From the abstract

Names both Alcohol and Lorazepam in its title.

Diazepam in the Treatment of Moderate to Severe Alcohol Withdrawal.

CNS drugs · 2017 · PMID 28101764

Comparative StudyReviewHuman subjects

“There is one instance in which diazepam should not be used: when intramuscular administration is the only option, the lipophilicity of diazepam can result in slow absorption-either lorazepam or, when rapid control of symptoms is required, midazolam should be used. The comparative pharmacokinetics of the benzodiazepines used in the treatment of alcohol withdrawal together with a comprehensive review of the literature on their use strongly suggest that diazepam should be the…”

Weintraub · From the abstract

Names Alcohol and Lorazepam 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

Track what you actually take.

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, Lorazepam, 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.
