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. | This reliable and more economical alternative to Frontline comes from a very reliable company, Elanco. Its main ingredient, fipronil, probably has the most clinical record of experience of efficacy over many years, in killing both adult fleas before they lay eggs, as well as various species of ticks. Its safety is touted by supposedly targeting only the nervous system of the pests. With cats, we always must be careful when evaluating the newer generation of emerging pesticides for fleas and ticks that are coming out, as kitties' detoxification pathways are typically more sensitive than dogs'. Most kitties tolerate this single spot application quite well. In addition to being waterproof, so important for outdoor kitties, this product is easier to apply than most competitors, as well as leaving no pungent or chemical smell like many over the counter competitor products. Most of my clients have found it as effective as Frontline, but not as quick as Advantage. Some clients have complained that it does not seem to repel the ticks, who can occasionally be found attached to the skin before they die. Not only it is important in using products like Easy Spot to prevent flea bite anemia in cats, and unsightly tapeworms, but in recent years, fleas have been shown to carry an increasing number of serious diseases and infections, including Bartonella species, amongst others. Another benefit of this product is that it is labeled as safe to use in pregnant or nursing cats. Side effects, although rare, may include topical irritation at the site of application, lethargy, as well as rare twitching reactions, agitation, and/or restlessness. These are typically short-lived, and fortunately, are very uncommon across pet populations that the product has been used. Some veterinarians and experts have wondered about the recent resistance of fleas to some of the fipronil-based products, but that has not been my experience. I give this product an overall rating of a 4, with an ease of application and efficacy of 4, as well. | 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. |
