Red-spur Valerian + Doxepin
Doxepin brand names: Sinequan, Doxepin, Zonalon.
We found no known interaction between Red-spur Valerian and Doxepin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Red-spur Valerian and Doxepin
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Doxepin and Red-spur Valerian in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Red-spur Valerian at all — not against Doxepin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Doxepin page
“Doxepin is a sedating tricyclic prescribed for depression, anxiety, and often sleep itself, and the people taking it tend to shop the same shelf where the trouble sits. Of the 186 supplements on file, 78 deepen its drowsiness, with alcohol (beer and wine carry major, well-documented ratings) and kava the clearest examples, and I would…”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Red-spur Valerian is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Red-spur Valerian reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Red-spur Valerian and Doxepin records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Red-spur Valerian
What is Red-spur Valerian?
- Sleep and relaxation
- Anxiety and nervousness
- Digestive upset
- Headaches
Red-spur valerian (Centranthus ruber) is a Mediterranean ornamental plant that has been used in folk medicine as a mild sedative, but there is almost no modern scientific research to support these uses. It is a different plant from true valerian (Valeriana officinalis), and its safety has not been well studied, so caution is warranted—especially during pregnancy, breastfeeding, and in children.
Centranthus ruber · Caprifoliaceae · Roots, leaves, and flowering tops · Rarely sold as a commercial supplement; traditionally used as teas or dried plant preparations

Doxepin Is Linked to Lower Levels of One Nutrient
Natural Medicines records Doxepin as a medicine that can lower these. This is not an interaction with Red-spur Valerian — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
