Red-spur Valerian + Allopurinol
Allopurinol brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric.
We found no known interaction between Red-spur Valerian and Allopurinol 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 Allopurinol
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 Allopurinol 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 Allopurinol, 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 Allopurinol page
“Allopurinol (Zyloprim) prevents gout attacks by lowering uric acid, and I would give this list real weight, because 5 of the 60 supplements and herbs on file carry a major rating. The largest cluster, 38 ingredients, is products that can stress the liver on their own, and regular beer or wine sits in that major group, since alcohol on…”

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 13, 2026. The Red-spur Valerian and Allopurinol 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

About Allopurinol
What Is Allopurinol Used For?
Brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric
Allopurinol tablets (including Zyloprim) are used in adults to treat the signs and symptoms of gout — including gout attacks, tophi (uric acid deposits), joint damage, and kidney problems caused by uric acid. Allopurinol tablets are also used in adults to reduce recurrent calcium oxalate kidney stones when uric acid in the urine is too high, even after lifestyle changes.
For adults and children with leukemia, lymphoma, or solid tumor cancers, allopurinol is used to control uric acid levels that rise during cancer treatment. The injectable forms — Allopurinol sodium for injection and Aloprim — are specifically for patients who cannot take medicine by mouth and are given intravenously (through a vein) in a hospital or clinical setting. Note: allopurinol tablets are not recommended for people who have high uric acid levels but no symptoms.
