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.

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 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.

The research

8 studies naming Clonidine and Melatonin.

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

Efficacy of clonidine and melatonin for treating insomnia in anxious children: a randomized comparison.

BMC pediatrics · 2026 · PMID 41781909

Randomized Controlled TrialComparative Study

“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.”

Jalali Firouzkohi et al. · From the abstract

Names both Clonidine and Melatonin in its title.

Preoperative anxiolytic effect of melatonin and clonidine on postoperative pain and morphine consumption in patients undergoing abdominal hysterectomy: a double-blind, randomized, placebo-controlled study.

The journal of pain · 2009 · PMID 19010741

Randomized Controlled Trial

“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.”

Caumo et al. · From the abstract

Names both Clonidine and Melatonin in its title.

Melatonin responses to clonidine and yohimbine challenges.

Journal of psychiatry & neuroscience : JPN · 1995 · PMID 7647083

Clinical TrialControlled Clinical Trial

“Only clonidine 300 micrograms produced a significant elevation in GH release. This study highlights the limitations of oral neuroendocrine challenge studies.”

Kennedy et al. · From the abstract

Names both Clonidine and Melatonin in its title.

Comparative evaluation of oral melatonin and oral clonidine for the attenuation of haemodynamic response to laryngoscopy and tracheal intubation-A prospective randomised double blind study.

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.”

Choudhary et al. · Authors' conclusion

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:

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 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.
