Clonidine and Melatonin: what the published research says
PubMed indexes 8 records that name Clonidine and Melatonin 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 Clonidine and Melatonin. 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 Clonidine and Melatonin.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Notably, the incidence of adverse effects did not differ significantly among the three groups. CONCLUSION: The findings of the present study indicate that both clonidine and melatonin are effective treatments for sleep disturbances in children with anxiety disorders.”
“Melatonin was effective for steal induction in 75% of children compared to 88% of children who had clonidine. Melatonin resulted less effective when administered early in the morning.”
“The preoperative anxiolysis with melatonin or clonidine reduced postoperative pain and morphine consumption in patients undergoing abdominal hysterectomy. The effects these 2 drugs were equivalent and greater than with placebo.”
Journal of affective disorders · 2001 · PMID 11511411
Clinical Trial
“Further indication is provided for presynaptic alpha2-adrenoceptor dysfunction in depression with the application of an alternative pharmacological challenge method.”
“Only clonidine 300 micrograms produced a significant elevation in GH release. This study highlights the limitations of oral neuroendocrine challenge studies.”
Romanian journal of anaesthesia and intensive care · 2020 · PMID 34056123
“Melatonin, clonidine, and dexmedetomidine are efficacious for producing preoperative sedation, reducing anxiety, postoperative pain, and emergence delirium.”
Indian journal of anaesthesia · 2020 · PMID 32934404
“Although both the drugs are effective, oral melatonin proved superior to oral clonidine in attenuating the haemodynamic response to laryngoscopy and tracheal intubation without any side effects.”
Names both Clonidine and Melatonin 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:
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 Clonidine, Melatonin, 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.
