Alcohol and Suvorexant: what the published research says

PubMed indexes 8 records that name Alcohol and Suvorexant 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 Suvorexant. 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

8 studies naming Alcohol and Suvorexant.

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

The dual orexin receptor antagonist suvorexant in alcohol use disorder and comorbid insomnia: A case report.

Clinical case reports · 2024 · PMID 38698873

Case Reports

“These data support abundant preclinical and emerging clinical data in this space. The findings from this case report highlight the potential for suvorexant to treat comorbid alcohol use disorder and insomnia with fully powered, randomized controlled trials moving forward.”

Campbell et al. · From the abstract

Names both Alcohol and Suvorexant in its title.

Psychomotor effects, pharmacokinetics and safety of the orexin receptor antagonist suvorexant administered in combination with alcohol in healthy subjects.

Journal of psychopharmacology (Oxford, England) · 2015 · PMID 26464455

Randomized Controlled Trial

“In conclusion, co-administration of 40 mg suvorexant and 0.7 g/kg alcohol had additive negative psychomotor effects. Patients are advised not to consume alcohol with suvorexant.”

Sun et al. · From the abstract

Names both Alcohol and Suvorexant in its title.

Evaluation of suvorexant effects on alcohol seeking and self-administration in baboons.

Drug and alcohol dependence · 2026 · PMID 41422738

Animal study

“Low dose suvorexant may acutely reduce drinking, but the magnitude of change may not be clinically meaningful. Higher doses of suvorexant may worsen heavy drinking. These data do not support suvorexant use to reduce alcohol intake during ongoing use.”

Pierce-Messick et al. · Authors' conclusion

Names both Alcohol and Suvorexant in its title.

Suvorexant for alcohol use disorder and post-traumatic stress disorder: study protocol for a phase II randomized clinical trial.

Trials · 2026 · PMID 41630040

Clinical Trial Protocol

“The recruitment of individuals with AUD and PTSD with sleep disturbances and who are intrinsically motivated to quit is a novel approach to screening pharmacotherapies by bridging the gap between experimental studies with non-treatment seekers and clinical trials with treatment-seeking individuals. ClinicalTrials.gov NCT06679062 "Suvorexant for Treatment of AUD and PTSD (SUV)." Registered on November 12, 2024.”

Ray et al. · From the abstract

Names both Alcohol and Suvorexant in its title.

Alternative use of suvorexant (Belsomra(®)) for the prevention of alcohol drinking and seeking in rats with a history of alcohol dependence.

Frontiers in behavioral neuroscience · 2022 · PMID 36620860

“Furthermore, 5 mg/kg SUV prevented the stress-induced reinstatement of alcohol-seeking behavior in dependent rats only. These results underscore the significance of targeting the Orx system for the treatment of substance use disorders generally and suggest that repurposing SUV could be an alternative approach for the treatment of AUD.”

Flores-Ramirez et al. · From the abstract

Names both Alcohol and Suvorexant in its title.

Suvorexant to treat alcohol use disorder and comorbid insomnia: Plan for a phase II trial.

Brain research · 2020 · PMID 31837287

ReviewHuman subjects

“We then highlight the role of the orexin system in both sleep-wake regulation and AUD. Finally, we discuss our plan for a Phase II double blind placebo controlled trial examining the effectiveness of suvorexant for the treatment of comorbid insomnia and AUD.”

Campbell et al. · From the abstract

Names both Alcohol and Suvorexant in its title.

A sleeping giant: Suvorexant for the treatment of alcohol use disorder?

Brain research · 2020 · PMID 30081035

ReviewHuman subjects

“In this mini review article, we explore the therapeutic potential of suvorexant for the treatment of AUD. In particular, we highlight that in addition to altering the motivational properties of alcohol, suvorexant may also address key physiological components associated with alcohol withdrawal and abstinence, such as sleep disruptions, which should in turn help reduce or prevent relapse.”

Campbell et al. · From the abstract

Names both Alcohol and Suvorexant 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:

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, Suvorexant, 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.
