Health & prevention Educational zone
Ticks, fleas, worming — educational guides to active substances only, vet-reviewed. We do not rank medicines.
Why we don't rank medicines. Oral tick & flea products (isoxazolines: Bravecto, NexGard, Simparica) are prescription medicines (POM-V in the UK; Rx via FDA in the US), and advertising prescription veterinary medicines to the public is restricted. This zone is educational only — active-substance guides, no ratings, no shopping links for medicines. Always decide with your veterinarian.
Active-substance guide (in preparation)
| Substance | Form | Availability | Worth knowing |
|---|---|---|---|
| Fipronil | spot-on | OTC | contact action; longest market record |
| Imidacloprid + flumethrin | collar | OTC / NFA-VPS (UK) | up to 8 months; size matters; see EPA incident discussions (Seresto) |
| Isoxazolines (fluralaner, afoxolaner, sarolaner) | chewable tablets | prescription | FDA fact sheet: potential neurologic adverse events (seizures) — discuss with your vet, especially with epilepsy history |
