Fluoxetine and SAMe: what the published research says
PubMed indexes 5 records that name Fluoxetine and SAMe 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 Fluoxetine and SAMe. 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
5 studies naming Fluoxetine and SAMe.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
The Journal of clinical psychiatry · 2006 · PMID 16848644
Systematic ReviewHuman subjects
“This systematic review highlighted that there are differences between fluoxetine and specific comparator antidepressants. Several of the differences met a prespecified criterion for clinical significance. The statistical approach adopted in this systematic review could represent a useful tool for putting clinical trial data into practice.”
The Journal of clinical psychiatry · 1996 · PMID 8591971
ReviewHuman subjects
“Sertraline was found to be modestly efficacious and associated with numerous side effects and discontinuation rates in patients who had previously discontinued fluoxetine.”
“The antidepressants bupropion and nortriptyline aid long-term smoking cessation. Adverse events with either medication appear to rarely be serious or lead to stopping medication. Evidence suggests that the mode of action of bupropion and nortriptyline is independent of their antidepressant effect and that they are of similar efficacy to nicotine replacement.”
Names Fluoxetine and SAMe together in an interaction, co-administration, or pharmacokinetic context.
Toxicology and applied pharmacology · 2021 · PMID 34610281
Comparative StudyHuman subjects
“In conclusion, P-gp plays an important role in the pharmacokinetic interaction between olanzapine and fluoxetine in rats. This study may provide a reference for the clinical safety of olanzapine combined with fluoxetine.”
Names Fluoxetine and SAMe together in an interaction, co-administration, or pharmacokinetic context.
The Canadian journal of neurological sciences. Le journal canadien des sciences neurologiques · 1994 · PMID 8000982
Clinical Trial
“No serious side effects were found. In this clinic population, fluoxetine and selegiline were used in combination without major side effects, but further observation is warranted.”
Names Fluoxetine and SAMe 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 Fluoxetine, SAMe, 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.
