Over time, generations of fleas can begin to develop a tolerance to the anti-pest spot ons on the market. By adjusting formulations, companies are able to keep their products effective. Advantage II has some differences, in terms of ingredients and effectiveness, as compared to its predecessor, Advantage. There are 3 new ingredients, all insect neurotoxins. These new ingredients make Advantage II more effective at killing pests than the original Advantage formulation.
WHAT TYPES OF PESTS DOES ADVANTAGE KILL?
The original Advantage was effective at killing adult fleas within 12 hours of application. This meant that your infected dog or cat or could find quick relief from adult fleas. Fleas in the larval stage would hatch and mature (a process that only takes a few days), and would then be killed.
Advantage II still provides relief from adult fleas within 12 hours, but the new formula offers additional protection as well. Advantage II breaks the flea lifecycle by stopping larval fleas from ever developing. This means your cat or dog receives complete flea protection for an entire month, at all stages of the flea lifecycle.
Advantage II for Dogs also kills lice.
Advantage topicals will not protect your pet from ticks -- K9 Advantix for Dogs, however, does protect against ticks.
HOW LONG DOES A DOSE LAST?
Both Advantage and the new Advantage II last for a full month after application. This is true even after baths or swimming, as the Advantage products are waterproof.
SHOULD MY PET BE KEPT INSIDE OR ALONE AFTER THE DOSE?
Your dog or cat should be kept away from other animals or close contact with people for approximately 30 minutes while the medication settles into their skin. In the first 30 minutes, other pets or children run the risk of getting the medication in their mouth or eyes if they touch your dog.
ARE THERE ANY SIDE EFFECTS TO ADVANTAGE OR ADVANTAGE II?
Both Advantage and Advantage II can potentially cause some temporary skin sensitivity. If such sensitivity lasts for more than a day or two, talk to your veterinarian. Do not get Advantage II in your pet’s eyes or mouth, and do not allow children to have contact with the application area. Because there are more chemicals in Advantage II, the risks are a bit higher than they were with Advantage, but not to a degree that should cause concern.
MY PET IS ONLY A FEW WEEKS OLD. CAN I STILL USE ADVANTAGE?
- Advantage II should not be used until puppies are at least 7 weeks of age.
- Advantage products should not be used until kittens are at least 8 weeks of age.
CAN I USE ADVANTAGE ON MY PREGNANT OR ELDERLY PET?
HOW DOES ADVANTAGE II WORK, AS COMPARED TO ADVANTAGE?
- Advantage II, like Advantage, is a topical medication. The medicine is applied to your cat or dog’s skin, typically between their shoulder blades where they can’t reach with their mouth. As with other topical parasite treatments, pests are killed on contact; fleas do not have to ingest Advantage II to die.
Advantage required adult fleas to ingest the medication, at which point they would be impacted by the insect-specific neurotoxins and die. Advantage II kills fleas on contact, with the addition of three new chemicals to its formula, that makes your dog or cat’s skin an entirely inhospitable environment for pests. Eggs are killed before they hatch. Adult fleas are killed and will fall off, or will be washed off in your dog’s next bath.
With proper and consistent use, Advantage II will provide superior pest control for you cat or dog, even above and beyond that of the original Advantage formula.
