The bottom line No known interaction

Field Scabious and Epoprostenol

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 Epoprostenol and Field Scabious 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 Field Scabious at all — not against Epoprostenol, 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 Epoprostenol’s Own FDA Label Lists

This is not an interaction — none of it involves Field Scabious. These are the most notable effects listed in the ADVERSE REACTIONS section of Epoprostenol’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.

  • A change in thyroid levels Worth acting on
  • A slow heartbeat Worth acting on
  • Blood clots Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on
  • Chest pain Worth acting on
  • A low platelet count Worth acting on
  • Anemia Worth acting on
  • Shortness of breath Worth acting on
  • Hives Worth acting on

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

From our pharmacist’s overview on the Epoprostenol page

“American hellebore tops my concerns for anyone on epoprostenol (Flolan), the continuous infusion that opens blood vessels in the lungs to treat pulmonary arterial hypertension. The herb lowers blood pressure even in small doses, and stacked on a medicine that already relaxes those vessels, the drop can be dangerous.”

About Field Scabious

What is Field Scabious?

  • Skin conditions like eczema and minor wounds
  • Cough and chest complaints
  • Sore throat
  • Mild digestive upset
  • Traditional 'blood cleansing' remedies

Field Scabious is a wild-growing herb used in European folk medicine, mostly for skin problems, coughs, and sore throats. There is very little modern scientific research to confirm any of these uses, so it should be viewed as a traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Knautia arvensis · Caprifoliaceae · Aerial parts (flowers, leaves, and stems), occasionally the root · Tea (infusion), tincture, dried herb, topical washes or compresses

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

Field Scabious: dosing

There is no established, standardized dose for Field Scabious. It has traditionally been prepared as a tea from the dried aerial parts or as a tincture, but reliable dosing guidelines from clinical research do not exist.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Epoprostenol

What Is Epoprostenol Used For?

Brand name: Flolan

Epoprostenol treats pulmonary arterial hypertension (PAH) (WHO Group 1), which is high blood pressure in the arteries of the lungs. It is used to improve exercise capacity.

Both Veletri and Epoprostenol for injection are approved for this use. Studies included mostly people with NYHA Functional Class III–IV symptoms (moderate to severe limits on activity). The causes were mainly idiopathic or heritable PAH, or PAH linked to connective tissue diseases.
