Capstar for Dogs: Fast-acting Oral Flea Treatment

Capstar is an oral flea treatment for dogs that generally resist messy topical treatments requiring application and rubbing. This vet-recommended tablet starts working fast and provides quick relief to your dog from the irritation of flea infestations. You may see the dead fleas falling off your dog after a single dose. Capstar is suitable for dogs and puppies aged 4 weeks and above, and weighing at least 2 lbs.

Capstar for Dogs Coverage

  • Kills adult fleas, including fleas that cause flea allergy dermatitis (FAD)
  • Treats flea infestations in dogs
  • Single treatment lasts for 24-48 hours
  • Helps treat flea outbreaks quickly

How Do Capstar Flea Tablets Work?

Capstar for Dogs contains nitenpyram, a powerful ingredient that targets the nervous system of parasites, causing rapid flea death. It starts killing fleas within 30 minutes and provides quick relief to your dog from infestations. In studies conducted by the manufacturer, Capstar showed over 90% effectiveness against adult fleas within 4 hours of administration. Additionally, you may give another dose of Capstar to your dog as often as once per day in case of flea re-infestations.

Instructions To Use Capstar

  • Weigh your dog prior to administration. Do not administer Capstar to dogs weighing less than 2 lbs.

  • Remove the Capstar tablet from the package.
  • Place the tablet directly into your dog’s mouth or hide it in food.
  • If you hide it in food, observe your dog closely to ensure that the entire dose is consumed.
