CapShield Maxx is a once-monthly beef-flavored oral flea tablet for dogs 8 weeks and older. It pairs nitenpyram, which starts killing fleas within about 30 minutes, with lufenuron, an insect growth regulator that stays in the bloodstream for roughly 30 days and stops new fleas from reproducing. That fast-kill plus life-cycle break is the same two-ingredient approach as Capstar plus Program, but in one tablet instead of two products. It suits owners who want to skip topical drops or collars and dose by mouth; it does not repel or kill ticks, so tick protection has to come from elsewhere.

CapShield Maxx Flea Protection Flavored Tablets are a once-monthly oral flea control for dogs. Each beef-flavored tablet combines two active ingredients. Nitenpyram starts working within 30 minutes. Lufenuron is an insect growth regulator (IGR) that stays in the bloodstream for about 30 days.
After the first day, any new flea that bites the dog will not fully reproduce, which breaks the flea life cycle. The tablets are color-coded by dose, which helps when dosing more than one pet in a household.
Give one tablet by mouth once a month, always with food. Choose the dose by your dog's weight. The tablets are for dogs and puppies 8 weeks or older and weighing at least 2 pounds. Do not use the dog formula on cats.
