Vet Review

The non-greasy, non-odor formulation is a definite plus when used on sensitive patients, especially cats.I find that advantage kills fleas and larvae more quickly than some of the other products out there, often resulting in quicker relief of flea allergy dermatitis symptoms in dogs and cats. Overall I have found it quite safe and have seen the fewest topical or rare systemic reactions in my practice over the years. The main disadvantage I have found is that in heavy flea infestations that the efficacy may wear off in less than one month, necessitating some vets to recommend more frequent off label use of this product every few weeks. It also does not control ticks as well on dogs and cats. I find that advantage works most effectively when combined with good environmental flea control at home.

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

I find that the effective combination of an ingredient like fipronil, along with the insect growth regulator methoprene, provides the best spectrum of activity and protection against all stages of the flea life cycle from egg through larval stage on to adult. Because of these two main ingredients and their method of action, I find that clients don't have to treat the environment as much. I find that this product tends to be safer in smaller breed animals when compared to its competition. I find its tick efficacy quite good. The fact that it is waterproof also allows clients, whose pets swim frequently, to confidently use this product during the swimming months. I also find that this product works the longest for fleas, while some of the competitive products have to be reapplied before the end of the month. The lack of label efficacy against mosquitoes and flies, as well as the fact that this product does not repel fleas or ticks are the two main disadvantages. As with any insecticidal products, I find that every pet is an individual, in terms of which of the products works best on them. When I am dealing with more of a flea issue in a patient, this is the product I will likely reach for first.
