This tablet delivers nitenpyram, an oral insecticide that enters the pet's bloodstream and is ingested by fleas as they feed, causing paralysis and death of the parasite. It is intended for dogs, puppies, cats and kittens weighing between 2 and 25 pounds and at least 4 weeks of age. The medication begins acting on adult fleas within 30 minutes of administration and is effective against the majority of fleas within a few hours. Each tablet is given orally, either placed directly in the pet's mouth or hidden in a small amount of food, and no additional equipment or preparation is required. Because the product targets only fleas already on the pet, it does not leave a residual barrier against new fleas picked up from the environment. This bulk pack supplies sixty individually dosed tablets, making it suited to households or facilities treating multiple animals or repeated infestations.
