What is Advantage®?
Advantage ® is a range of medications used to treat and prevent flea infestations in cats and ferrets, and fleas and lice in dogs. Advantage® is effective against adult fleas and flea larvae. It is available in various formulations (combined with other drugs) and strengths. Only use certain Advantage ® products as recommended by your vet.
Advantage Multi ® contains the drug moxidectin, which helps prevent Advantage ® for dogs and cats in addition to preventing heartworms, hookworms, and roundworms. Advantage Multi ® for cats also protects against ear mites, while Advantage Multi ® for dogs also protects against whipworms and sarcoptic mange. It is only available by prescription. Talk to your vet about whether Advantage Multi ® is right for your pet. Always read and follow all label instructions carefully.
K9 Advantix ® II is only used on dogs to treat, prevent and repel fleas, ticks, lice, mosquitoes and bitflies. It contains permethrin, which is not safe for cats.
These medications are dosed separately for dogs and cats and given by weight. Therefore, it is important that you use the right type and size of medicine for your pet. Using cat medicines on dogs or using canine medications on cats can cause serious problems, including lack of effectiveness or an overdose.
How Advantage®, K9 Advantix® II, and Advantage Multi® work
The main ingredient in the Advantage product line is imidacloprid, which blocks certain naturally occurring chemicals found in parasites and are responsible for transmitting nerve signals. Imidacloprid disrupts their central nervous system and causes the parasite to die. When used as a topical product, imidacloprid does not enter your pet’s bloodstream.
The second active ingredient in Advantage ® and K9 Advantix ® II is pyriproxyfen, which mimics a growth hormone that is naturally found in parasites. Pyriproxyfen targets young and immature parasites by preventing them from growing into adulthood. It may also prevent egg production in female insects.
K9 Advantix ® II also contains the ingredient permethrin, which acts similarly to imidacloprid. Permethrin blocks certain chemical messengers in ticks and overwhelms their nervous systems, leading to paralysis and death.
Permethrin is toxic to cats. K9 Advantix ® II should never be used on cats. Cats should not be near dogs that have been treated with K9 Advantix ® II within the first 24 hours after use.
Advantage Multi® products also contain the ingredient moxidectin, which moves chloride, a naturally occurring electrolyte, across the cell membranes of certain susceptible worms, such as heartworms, roundworms, and hookworms. By overloading chloride into these worms, it impairs electrical activity in their nervous system, leading to muscle paralysis and death.
