Vet Review

An exciting and brand new product now available combines the main ingredient of Interceptor milbemycin with a powerful flea insecticide known as spinosad. Given as a once monthly heartworm preventative, this product also will control and prevent whipworms, hookworms and roundworms, in addition to preventing heartworms. The additional ingredient spinosad allows effective flea and these internal parasite control all in one pill, making it quite convenient for clients. As with any pesticide rare digestive tract and neurological side effects may occur but this has not been a major problem in clinical trials. Since it is relatively new I will have to see how this product performs on the fleas but it seems to have excellent potential. I give this product an overall rating of a 5 with an ease of administration a 5 as well, taste a 5.

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.
