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.

I have started to use this product over the past several months and have mixed feelings about it. A big advantage is the ease of administering the beef and pork flavored tablet but it should be administered on full stomach. And while it avoids the oily liquid pesticides on the back that many clients don ' t like, if a pet is allergic to beef or pork this is a big disadvantage. The best thing about this product (which is similar to Capstar) is the quick kill of adult fleas working within 30 minutes and being almost 100 percent effective against fleas within 4 hours of giving it, and lasting for a month!!! (much longer than a Capstar pill.) A big problem is not only the expense but it also has no tick coverage. In my experience and opinion, I have also seen several dogs vomit when given this pill and it is really not supposed to be used in patients with seizure disorders, which is also a concern of mine in terms of safety. Along the same line, it is not supposed to be used in pregnant or nursing females, as from what I understand when the product was tested there were supposed loss of litter during pregnancy, poor weight gain of puppies and vomiting, the latter symptom which I have seen in clinical practice. In general I am always a little worried about products not approved for young puppies, as the puppies have to be at least 14 weeks of old, according to the label use of this product. It is not a cheap product, and for the above reasons I don't use it often even though it is tremendously effective against fleas. For the reasons stated above, I therefore give this product an overall rating of 2 with effectiveness (for fleas) of 4, the ease of use a 5, and the taste a 4. I still prefer Front line, Advantage and K9 Advantix despite the oily spot because of the increased coverage of parasites, and my concerns about safety

This product is a wonderful economic alternative for clients who have used the Frontline product. It contains the same exact main ingredient as Frontline, Fipronil, which has been probably the number one used flea and tick preventative ingredient by veterinarians over decades now. Not only does it kill fleas and many species of ticks that carry Lyme and other diseases, but also can help in controlling scabies mange mites, as well, in those cases. It certainly is a much cheaper alternative to Frontline or Advantage products. Some excellent advantages include it being waterproof, as well as being safe to use in pets as young as 8 weeks of age. There may be a rare skin irritation side effect at the site of application, but other reactions are even more rare. I have occasionally seen digestive upset with this product. I would also not use it in dogs with a history of chronic seizure disorders. Because of its long-term reliability and safety, I give this product an overall rating of a 4.5, with an ease of application of 4.5.
