Canadian Fleabane and Clevidipine

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 Clevidipine and Canadian Fleabane 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.

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.

How we checked

Why No Interaction Is Listed for Clevidipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Clevidipine is filed under a single classification — antihypertensive drugs. Canadian Fleabane has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Clevidipine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Clevidipine page

“When you are on clevidipine (Cleviprex), a hospital IV drip used to bring dangerously high blood pressure down fast, every one of the 119 supplements and herbs listed here pushes on the very thing the drug controls, and that earns this list real caution. Most of the 104 moderate entries, everyday products like fish oil among them, add…”

About Canadian Fleabane

What is Canadian Fleabane?

  • Diarrhea
  • Minor bleeding
  • Urinary complaints
  • Digestive upset
  • Sore throat and inflammation

Canadian Fleabane is a common North American weed used in traditional medicine for diarrhea, minor bleeding, and urinary issues, but high-quality human studies are lacking. Because its safety has not been well studied, it is best to talk with your pharmacist or doctor before using it, and to avoid it during pregnancy and breastfeeding.

Erigeron canadensis · Asteraceae · Aerial parts (leaves, stems, flowers) and the essential oil · Tea, tincture, dried herb, liquid extract, essential oil

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

Canadian Fleabane: dosing

There is no established, science-based standard dose for Canadian Fleabane. Traditional preparations such as teas and tinctures vary widely in strength, and product labels differ from brand to brand.If you choose to use a commercial product, follow the directions on the label and do not exceed them. The essential oil is very concentrated and is not meant to be taken by mouth without professional guidance.
