Doxepin and Melatonin: what the published research says

PubMed indexes 2 records that name Doxepin 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 Doxepin 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

2 studies naming Doxepin and Melatonin.

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

Nocturnal melatonin secretion and sleep after doxepin administration in chronic primary insomnia.

Pharmacopsychiatry · 1996 · PMID 8895944

Clinical TrialRandomized Controlled Trial

“These findings indicate that this tricyclic antidepressant not only improves sleep and but also preserves the secretion of a hormone which is believed to play a special role in the circadian sleep-wake rhythm. Long-term doxepin treatment of chronic insomniac patients not only improves sleep but also restores nocturnal melatonin secretion in these patients.”

Hajak et al. · From the abstract

Names both Doxepin and Melatonin in its title.

Addressing Sleep Disorders in Psychiatry: Comparing the Use of Melatonin, Trazodone, and Doxepin.

Cureus · 2024 · PMID 39872559

“Conclusion In psychiatric patients, trazodone was the most successful medication for enhancing sleep quality; however, other groups cannot use it due to its adverse effects. For patients who were more likely to have side effects, melatonin was a safer option, but doxepin offered a good balance between effectiveness and tolerability.”

Mamoon et al. · From the abstract

Names both Doxepin 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 Doxepin, 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.
