Whether your dog is big or small, Simparica protects them against harmful fleas, ticks and mites. A tasty chewable tablet that’s easy to give, with or without food.

Works fast and lasts for dogs from 1.3kg and 8 weeks of age.

Simparica can be used as a strategic tool for dogs with flea allergy dermatitis (FAD). Dogs that suffer from FAD need fast relief. It starts killing fleas 3 hours after administration and completely kills all fleas in 8 hours. Remember, more fleas will jump on your pet from the environment - Simparica will provide sustained protection for 5 full weeks.

Easy to remember; 1 tasty chewable tablet that your dog will love, that offers 5 weeks protection.

  • Proven protection from reinfestation
  • Kills fleas fast before they can lay eggs
  • Controls mites reducing skin irritation
  • Kills ticks fast for rapid relief without losing efficacy
  • Effectiveness isn’t compromised by intensive bathing regimes.
