Mouse-ear Hawkweed and Phendimetrazine

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 Phendimetrazine 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 Phendimetrazine, 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.

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 Phendimetrazine’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. 2 of them are worth acting on rather than waiting out — marked below.

  • Pain or burning when passing urine Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Phendimetrazine. Read the label on DailyMed › 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.

From our pharmacist’s overview on the Phendimetrazine page

“Of the 17 supplements on file for phendimetrazine, an appetite-suppressant stimulant prescribed short term for weight loss, activated charcoal is the one that demands real caution. Charcoal binds medications in the gut and can sharply cut how much of a drug your body absorbs, leaving you with less appetite control than your prescriptio…”

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).

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.

About Phendimetrazine

What Is Phendimetrazine Used For?

Brand names: Plegine, Metra, Weightrol

Phendimetrazine tartrate is used to help manage exogenous obesity (excess body weight from outside causes like diet and lifestyle) as a short-term addition to a calorie-restricted diet. It is intended for adults with a BMI of 30 or higher, or a BMI of 27 or higher when other risk factors — such as high blood pressure, diabetes, or high cholesterol — are also present.

It is approved for use as monotherapy only, meaning it must not be combined with other weight-loss drugs or stimulants. Both the tablet form and the extended-release capsule form are approved for this purpose. This medication is meant to be used for only a few weeks as part of a broader weight-management plan.
