Zoetis Simparica (Sarolaner) Tick and Flea Control Tablet for Dogs (1 tablet)

Simparica is an ectoparasiticide — meaning it targets external parasites that live on or bite your dog. Its single active ingredient, sarolaner, is absorbed into your dog's bloodstream after they eat the tablet. When a tick or flea bites and begins feeding, it ingests the sarolaner and dies rapidly. This means Simparica does not repel parasites before they bite — instead, it kills them quickly once they do, preventing them from feeding long enough to cause disease or lay eggs.

• Tick Control: Simparica is effective against the tick species most commonly found on Indian dogs, including the brown dog tick (Rhipicephalus sanguineus) — the primary vector for serious diseases like canine ehrlichiosis and babesiosis across Indian cities. It also kills the black-legged tick, American dog tick, lone star tick, Gulf Coast tick, and Asian longhorned tick. In clinical studies, Simparica maintained 100% effectiveness against ticks through 35 days after dosing (per Zoetis data on file), meaning even if you're a few days late on the next dose, your dog remains protected.

• Flea Control: Simparica begins killing adult fleas within 3 hours of your dog eating the tablet and reduced live flea counts by more than 96% within 8 hours in controlled studies (per veterinary consensus). Critically, it kills fleas before they can lay eggs — breaking the flea life cycle and helping to clear an existing infestation in your home over time. For dogs with flea allergy dermatitis, a condition where even a single flea bite triggers intense itching and skin reactions, this speed of kill makes a significant difference to day-to-day comfort.

• Extra-Label Use - Mange: Some veterinarians prescribe Simparica off-label for the treatment of demodectic mange, sarcoptic mange, and ear mites in dogs. If your vet has recommended Simparica for this purpose, follow their instructions carefully, as the dosing schedule and duration may differ from standard monthly tick and flea use.
