Overview of Lufenuron for Dogs and Cats

  •  Lufenuron, also commonly known as Program®, is used to control flea populations in dogs and cats.  Lufenuron is commonly bombed with other drugs for various flea prevention medications.
  • Control of insect parasites, such as fleas, can be achieved by a number of approaches. One of the most novel methods is the use of insect growth regulators. These drugs arrest the development of insect parasites while demonstrating great safety when administered to animals.
  • Lufenuron belongs to a class of drugs known as insect development inhibitors/insect growth regulators and the formal class is called “Chitin synthesis Inhibitor”.
  • Lufenuron inhibits insect development within the insect egg. This prevents the egg from maturing to an adult insect.  Lufenuron is most commonly administered for flea control in dogs and in cats. It does not control ticks.
  • Dogs and cats already affected with fleas, or those with flea-allergy dermatitis, first should be treated with an insecticide approved for that species.
  • Lufenuron is a prescription drug and can only be obtained from a veterinarian or by prescription from a veterinarian.
