What are the drops for cats called that treat fleas and worms? - in detail
The cat topical medication that simultaneously eliminates fleas and treats internal parasites is commonly referred to as a combination spot‑on treatment. It is applied directly to the skin, usually at the base of the neck, and provides systemic protection against ectoparasites and endoparasites.
Typical commercial products include:
- «Revolution Plus» – active ingredients selamectin (targets fleas, ear mites, heartworm, roundworms, hookworms, and tapeworms) and sarolaner (enhances flea efficacy).
- «Advantage Multi» – imidacloprid (kills adult fleas) combined with pyriproxyfen (prevents flea development) and milbemycin oxime (treats roundworms, hookworms, and heartworm).
- «Broadline» – imidacloprid, pyriproxyfen, selamectin, and milbemycin oxime, covering a broader spectrum of worms including tapeworms.
- «Stronghold» – selamectin and sarolaner, offering flea control and treatment of roundworms, hookworms, and heartworm.
- «Bravecto Spot‑On» – fluralaner (provides long‑lasting flea kill) paired with milbemycin oxime for worm control.
Mechanisms of action:
- Imidacloprid interferes with insect nervous system receptors, causing rapid flea death.
- Pyriproxyfen mimics juvenile hormone, preventing flea eggs and larvae from maturing.
- Selamectin binds to chloride channels in parasites, leading to paralysis and death of fleas, ear mites, and several worm species.
- Milbemycin oxime disrupts neurotransmission in nematodes, eliminating roundworms and hookworms.
- Sarolaner and fluralaner belong to the isoxazoline class; they block GABA‑gated chloride channels in insects, resulting in sustained flea mortality.
Administration guidelines:
- Dosage calculated according to the cat’s body weight; each product provides specific weight ranges on the label.
- Apply the entire dose to a single spot on the skin, avoiding contact with eyes or mouth.
- Re‑application intervals vary: monthly for most formulations, up to three months for long‑acting isoxazoline products.
- Ensure the cat is dry and calm during application; allow the liquid to absorb before handling.
Safety considerations:
- Prescription required in many regions; veterinary assessment confirms suitability, especially for pregnant or lactating queens, kittens under eight weeks, or cats with pre‑existing health conditions.
- Reported adverse reactions include transient skin irritation, temporary lethargy, or mild gastrointestinal upset.
- Over‑dosage may result in neurotoxic signs; follow label instructions precisely.
These combination spot‑on products provide an efficient, single‑application solution for simultaneous flea eradication and worm treatment in domestic cats.
