Pyrethrum and Florbetaben F-18

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 Florbetaben F-18 and Pyrethrum 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 Pyrethrum at all — not against Florbetaben F-18, 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.

Pyrethrum safety at a glance

What to actually watch for

What Pyrethrum Itself Has Been Linked To

This is not an interaction — nothing below involves Florbetaben F-18. It is the side-effect record for Pyrethrum on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Pyrethrum, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    “Pyrethrum has limited toxicity. The symptoms of overdose include headache, tinnitus, nausea, tingling of fingers and toes, respiratory disturbances, and other symptoms of neurotoxicity (18). The pyrethrum flower or derivatives of it might cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family.”

Everything above comes from the Natural Medicines adverse-effect record for Pyrethrum — expand a row for the licensed statement it rests on. We haven’t matched Florbetaben F-18 to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Florbetaben F-18.

About Pyrethrum

What is Pyrethrum?

  • Natural insect repellent
  • Killing fleas, lice, and other pests
  • Garden and household insecticide
  • Traditional use against parasites

Pyrethrum is a daisy-like flower whose extracts (called pyrethrins) are widely used as a natural insecticide for plants, pets, and lice. It is not a supplement meant to be taken by mouth, and there is no good evidence supporting any internal health use. If you use pyrethrum products, treat them as pesticides and follow label directions carefully.

Tanacetum cinerariifolium · Asteraceae · Dried flower heads · Insecticide powders, sprays, and extracts (pyrethrins); rarely used internally

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

Pyrethrum: dosing

There is no established or recommended internal dose for pyrethrum, and it should not be taken as a supplement. For insecticide, lice, or flea products, the correct amount depends entirely on the specific product.Always follow the directions on the product label exactly, and do not use more or more often than directed.
