Mouse-ear Hawkweed + Tipiracil Hydrochloride, Trifluridine
Tipiracil Hydrochloride, Trifluridine brand name: Lonsurf.
We found no known interaction between Mouse-ear Hawkweed and Tipiracil Hydrochloride, Trifluridine 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. Additionally, although there is no interaction, the label for Tipiracil Hydrochloride, Trifluridine states a food rule worth keeping to.
Mouse-ear Hawkweed and Tipiracil Hydrochloride, Trifluridine
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 Tipiracil Hydrochloride, Trifluridine 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 Tipiracil Hydrochloride, Trifluridine, 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.

At least one FDA label for a product containing Tipiracil Hydrochloride, Trifluridine says to take it with food. If you take Mouse-ear Hawkweed on an empty stomach out of habit, keep them separate — and take Tipiracil Hydrochloride, Trifluridine with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Tipiracil Hydrochloride, Trifluridine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
2 DOSAGE AND ADMINISTRATION Recommended Dosage : 35 mg/m 2 /dose orally twice daily with food on Days 1 through 5 and Days 8 through 12 of each 28-day cycle.
