Vet Review

When the Activyl product line came out several years ago, it was touted as a totally novel new product on the market that would not have the problems of emerging flea resistance to products that has believed to been increasing in recent years with the old standby products in some cases. It supposedly works through a unique process of bioactivation using only the flea enzymes in activating the main ingredient, indoxacarb, in killing fleas. Along with the permethrin ingredient for tick coverage and control, it would seem like this would be a first line or excellent choice for those looking for a novel and comprehensive flea/tick product for their dogs. And while it is also effective in preventing flea eggs and larvae from developing as well, and can be highly effective in today's war against fleas and ticks, I have seen occasional problems with this product, as reported by clients. While its deeper penetration in the fatty oils of the skin may be a benefit, and while the product is not reported to be absorbed systemically, I have seen occasional and severe side effects reported by animal guardians. As with most other topical products in this venue, this particular product can occasionally cause irritation and itching at the site of application, which while usually only transient for a day or two, in some pets the itching and allergic reaction has been noted to intensify, necessitating anti-itch medications for relief. Some clients have also reported an odd odor from the application site for a while, as well as an oily film, which may persist for a few days. While many clients do report this product highly effective when other competitor products may have failed them recently, these occasional reactions are important to note, especially in a very sensitive or geriatric animal, and/or one with a chronic medical condition. On very rare occasions, clients have reported digestive side effects, as well as rare neurological weakness, stiffness or even spasms. While the vast majority of clients are satisfied with this product's performance and reliability, the decision on using this stronger, newer way of flea and tick control, should be made after careful consideration of patient history, as well as discussion with the local veterinarian. I give this product an overall rating of a 4, with an ease of use of a 5, with a mid-rating safety level of 3.

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
