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 Clonazepam

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 Clonazepam 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 Clonazepam, 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.

What Clonazepam’s Own FDA Label Lists

This is not an interaction — none of it involves Red-spur Valerian. These are the most notable effects listed in the ADVERSE REACTIONS section of Clonazepam’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Pain or burning when passing urine Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • Dehydration Worth acting on
  • Trouble passing urine Worth acting on
  • Unsteadiness Worth acting on
  • Hallucinations Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • Low mood Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Clonazepam. Read the label on DailyMed › Red-spur Valerian’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Red-spur Valerian side to compare — that is a limit of the record, not a statement that Red-spur Valerian has no side effects.

From our pharmacist’s overview on the Clonazepam page

“Clonazepam (Klonopin) slows brain activity to control seizures and panic, and most of what interacts with it pushes in one of two directions: deepening that sedation or changing how much drug is in your blood. This is a list to approach carefully.”

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).

About Red-spur Valerian

What is Red-spur Valerian?

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

An interaction check asks whether these two react with each other — it does not ask whether Red-spur Valerian is a good idea for someone in your situation. Here is what our Red-spur Valerian record says about it on its own.
