The bottom line No known interaction

We found no known interaction between Mouse-ear Hawkweed and Donepezil 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.

Mouse-ear Hawkweed and Donepezil

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 Donepezil and Mouse-ear Hawkweed 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 Mouse-ear Hawkweed at all — not against Donepezil, 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 Donepezil’s Own FDA Label Lists

This is not an interaction — none of it involves Mouse-ear Hawkweed. These are the most notable effects listed in the ADVERSE REACTIONS section of Donepezil’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. 3 of them are worth acting on rather than waiting out — marked below.

  • Bleeding in the gut Worth acting on
  • Seizures Worth acting on
  • Bleeding or bruising Worth acting on
  • Weight loss
  • Reduced appetite
  • Muscle pain
  • Trouble sleeping
  • Tiredness mentioned in 4.8% of FDA reports for Donepezil
  • Diarrhea mentioned in 5.0% of FDA reports for Donepezil
  • Nausea mentioned in 4.6% of FDA reports for Donepezil

Showing the 10 most notable of 11 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Donepezil. Read the label on DailyMed › Where a percentage is shown, it is the share of 37,026 voluntary FDA FAERS reports for Donepezil that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Mouse-ear Hawkweed’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Mouse-ear Hawkweed side to compare — that is a limit of the record, not a statement that Mouse-ear Hawkweed has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Mouse-ear Hawkweed 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 Mouse-ear Hawkweed reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Mouse-ear Hawkweed and Donepezil 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 Mouse-ear Hawkweed

What is Mouse-ear Hawkweed?

Mouse-ear Hawkweed
  • Urinary tract and kidney support
  • Mild diuretic (increasing urine flow)
  • Digestive complaints
  • Coughs and respiratory irritation
  • Wound and skin care (astringent)

Mouse-ear hawkweed is a traditional European herb used mainly for urinary, digestive, and respiratory complaints, but modern human studies are very limited. Because good safety and effectiveness data are lacking, it is best used cautiously and avoided in pregnancy and breastfeeding. Talk with your pharmacist or doctor before trying it, especially if you have a health condition or take medications.

Pilosella officinarum · Asteraceae · Aerial parts (leaves, flowers, and stems), usually the whole flowering herb · Tea (infusion), liquid extract or tincture, dried herb, capsules

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

Mouse-ear Hawkweed: dosing

There is no established standard dose for mouse-ear hawkweed. Traditional use has involved teas made from the dried herb and liquid extracts or tinctures, but reliable, science-based dosing is not available.If you choose to use a product, follow the directions on the label and do not exceed the suggested amount.
