Vet Review

This topical product that has been around for years is really a potluck type product in my opinion and experience. Many of my clients, who could not afford the other commonly veterinary recommended topical flea/tick pesticides, have found this product a quite helpful much more economic and effective product than the more expensive competitors. . However I have had equal number of clients, who have used this product, been quite disappointed with the results, and their infestations seemed to have gotten worse after starting with this product. I personally don't recommend this product,for my biggest concern that overrides any economic savings that clients have, are the sometimes serious side effects I have seen with certain sensitive pets in my practice and experience. This has ranged from local irritation and greasiness in the coat, to an almost burn like eruption at place of application, to more serious systemic effects like excess drooling, ear itching/irritation and in rare cases neurological side effects including suspected seizures shortly after application. Although these side effects are not common, I feel their severity over rides my ability to recommend this product, I would stick with the more widely veterinary recommended products like Frontline, Advantage or Advantix. I therefore give this product an overall rating of a 2. Its efficacy is a 2 and its ease of use is a 4.

While an economical alternative to the more expensive topicals like Advantage or Frontline, because of safety concerns I cant recommend this product to my clients. Over the years I have seen too many side effects from topical irritation to rare and sometimes severe neurological and/or seizures in some pets. I have also found it to not be as effective in flea control as with advantage or front line. While it is marketed to work against adult fleas, prevent development of flea eggs into larvae and adults, as well as killing ticks for 3 months, once an infestation is in place I have not found this product to be as effective as the competitors in my opinion and experience. One of the nice few benefits I have seen is the killing and repelling of mosquitoes with use of this spot on product. While it is easy to apply and water based, many of my clients have reported irritation reactions as well as greasy fur at the site of application. It is for these reasons that I give this product an overall rating of a 2 with an efficacy of a 2 with ease of use a 5.
