Vet Review

Belonging to the latest generation of flea/tick parasiticides(known as Isoxazoline medications), these palatable, beef flavored chewable tablets kills fleas quite effective, with most adult fleas being killed within 8 hours. One of the downsides, as compared with Vectra 3D is that Credilio does not repel either fleas or ticks, and has no effect on biting mosquitoes, which are the main vectors that transmit heartworms to dogs. Credilio and products of its class are one of the most effective products against several species of severe disease transmitting ticks, including ones that transmit Lyme Disease, Ehrlichiosis, Rocky Mountain Spotted Fever and Anaplasmosis, which have been increasing in incidence in recent years. As with other members of this drug class, we have also used this drug in treatment and prevention of both demedex mites and scabies mites, although this is an off label use. Giving with a full meal reduces risks of digestive reaction. Overall the tablet is well tolorated, but occasional diarrhea, vomiting or digestive upset is seen. I would look to one of the other products like Vectra 3D, if there is a history of significant neurologic disease or seizures. I give this product an overall rating of a 4 out of 5.

As most exterminators will tell you, the battle with external parasites and pests is an always evolving battle, as over time, parasites will develop partial resistance to products that had once worked almost perfectly in the past. This has been my experience with some of the older flea/tick formulations and has been reported by my veterinary colleagues and clients alike on occasion. While the older products are mostly still effective, companies are always researching new formulations to stay one step ahead of the development of resistance in the parasites. One of the latest formulations, Frontline Gold takes advantage of newer technologies and now has added an additional insect growth regulator, Pyriproxyfen, to its original formulation, to help enhance the efficacy of the Frontline plus product. The Frontline product is thus able to kill the next generation of flea larvae and eggs even more effectively by breaking the life cycle of the flea. The likelihood of flea immune resistance to this new triple action formula is thus significantly reduced. Given the increasing global warming seen in recent years, the expanding and increasing flea populations in heavily infested areas, however, do require a truly holistic approach by the animal guardian in treating the home, environment and yard for optimal flea control, as it is important to keep in mind that much of the flea life cycle still occurs in the home. While many clients find the more easily applied, self-puncturing tube dispensing method(often only requiring the use of one hand) to the old product, other clients find it difficult to see if all of the product has been dispensed from the colored tube. This new product, however, is quite effective, with only rare topical irritation at the site of the application an only rare complication. With that being said, I give this product an overall rating of a 5, with an ease of application of 4.

For clients that prefer an outstanding topical medication that has thus far had an excellent record of efficacy against both fleas and ticks. This product includes 3 very powerful and synergistic flea/tick pesticides that work in slightly different ways, with one preventing development of flea eggs and larvae, while another ingredient quickly kills; killing probably the fastest of any products on the market, starting to act within 5 minutes. Ticks will take somewhat longer, but within 2 days most ticks are killed. The addition of the permethrin ingredient does add the benefit of this product in BOTH repelling and killing ticks, , as well as the additional benefit of killing and repelling mosquitoes, the main vectors of heartworm disease in dogs and cats. As with other topicals, occasionally pets will develop an irritation or sensitivity at the sight of application, with some pets being occasionally restless, agitated, or fidgety. On rare occasions vomiting and/or diarrhea may be seen but this has not been much of a problem in clinical practice, where most pets seem to tolerate the product quite well. While the trio of main ingredients in this product seem to provide additional efficacy and coverage of various stages of the external parasites, including the benefit of repelling them, I am always a bit cautious about combination products like this, which rarely may lead to unknown chronic side effects that we are not yet aware of. With that consideration, this product is still an excellent and effective choice. I give this product an overall rating of 4 out of 5.
