How to Administer: Flea populations are more prevalent in the spring when cold temperatures turn warmer, making it a more hospitable climate for parasites. You are more apt to encounter fleas in warm, humid areas. However, because weather patterns are always variable and unpredictable, it is important to use PROGRAM Flavor Tabs all year-round. Give PROGRAM Flavor Tabs oral flea control once a month. Always give PROGRAM with a meal to ensure proper absorption. Make sure all pets in your home are protected against fleas.

PROGRAM Flavor Tabs are available in four sizes for oral administration to dogs and puppies according to their weight (see Dosage section). The active ingredient of PROGRAM Flavor Tabs is lufenuron, a benzoylphenylurea derivative with the following chemical composition: N-[2,5-dichloro-4-(1,1,2,3,3,3, -hexafluoropropoxy)-phenylaminocarbonyl]-2,6-difluorobenzamide. Benzoylphenylurea compounds, including lufenuron, are classified as insect development inhibitors (IDIs). As an insect development inhibitor, PROGRAM Flavor Tabs does not kill adult fleas, but effectively and safely controls flea populations on your pet through a mode of action which breaks the flea's life cycle at the egg stage. PROGRAM Flavor Tabs are labeled for use in dogs and puppies, six weeks of age and older, for the prevention and control of flea populations. Lufenuron controls flea populations by preventing the development of flea eggs and does not kill adult fleas. Concurrent use of insecticides may be necessary
