Vet Review | 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. | Fleas are easily the most common external parasite that plague cats throughout the country. Fleas have been shown to not only cause weakness and anemia in affected cats, but also transmit dangerous infectious diseases, including bartonellosis, an also increasing threat to humans. Cheristin is made with the same main ingredient as Comfortis for cats, and acts uniquely on the nervous system of the flea. Unlike flea prevention tablets, Cheristin starts killing fleas within 30 minutes and almost 100 percent of fleas within 12 hours. With the easy to use applicator, this product has been shown to be quite effective for one month. The most common, yet rare side effect I have seen in cats is an allergic reaction or hair loss at the site of application, and even less commonly vomiting and lethargy. It is an excellent and fast acting, effective product with an overall rating of a 4.5 with an ease of administration of a 5. | 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 |
