Scarlet Pimpernel and Revefenacin

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 Revefenacin and Scarlet Pimpernel 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 Scarlet Pimpernel at all — not against Revefenacin, 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 Revefenacin’s Own FDA Label Lists

This is not an interaction — none of it involves Scarlet Pimpernel. These are the most notable effects listed in the ADVERSE REACTIONS section of Revefenacin’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. 5 of them are worth acting on rather than waiting out — marked below.

  • Trouble passing urine Worth acting on
  • Wheezing Worth acting on
  • Raised blood pressure Worth acting on
  • A higher chance of infection Worth acting on mentioned in 5.8% of FDA reports for Revefenacin
  • An allergic reaction Worth acting on
  • Cough mentioned in 6.8% of FDA reports for Revefenacin
  • Sore throat

  • Back pain
  • Headache mentioned in 6.6% of FDA reports for Revefenacin

From the ADVERSE REACTIONS section of the FDA label for Revefenacin. Read the label on DailyMed › Where a percentage is shown, it is the share of 740 voluntary FDA FAERS reports for Revefenacin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Scarlet Pimpernel’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Scarlet Pimpernel side to compare — that is a limit of the record, not a statement that Scarlet Pimpernel has no side effects.

From our pharmacist’s overview on the Revefenacin page

“Revefenacin (Yupelri) is an inhaled anticholinergic that keeps airways open in COPD, and this list warrants genuine care rather than a quick skim. Of the 46 supplements on file, three carry a major rating, and most of the rest share revefenacin's drying, anticholinergic action, so combining them can stack up dry mouth, blurred vision,…”

About Scarlet Pimpernel

What is Scarlet Pimpernel?

  • Skin conditions and wounds
  • Liver and gallbladder complaints
  • Respiratory ailments
  • Mild mood or 'melancholy' (folk use)
  • Urinary complaints

Scarlet Pimpernel is a small wild flowering plant with a long history in folk medicine, but there is very little modern scientific evidence to support any of its uses. It contains compounds called saponins that can be irritating and potentially toxic, so it is generally not recommended for internal use. If you are considering it, talk with a pharmacist or doctor first.

Lysimachia arvensis · Primulaceae · Aerial parts (leaves, flowers, and stems) · Dried herb, tinctures, infusions, and topical preparations

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

Scarlet Pimpernel: dosing

There is no established, standardized safe dose for Scarlet Pimpernel. Because of its potential toxicity and the lack of quality research, no specific milligram amount can be recommended.If you find a commercial product, follow the label directions exactly and do not exceed them.

About Revefenacin Oral Inhalation

What Is Revefenacin Oral Inhalation Used For?

Brand name: Yupelri

Yupelri (revefenacin) inhalation solution is approved for the maintenance treatment of COPD (chronic obstructive pulmonary disease) in adults. It is used every day to help keep airways open and make breathing easier over the long term.

Yupelri is not a rescue inhaler — it will not relieve a sudden COPD flare-up or acute breathing attack. A separate short-acting bronchodilator is needed for those situations.
