Vet Review | Currently under review | 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. | Within the past year there has been an exciting development in the battle against fleas and ticks.For years, veterinarians have relied on topical medications for control of fleas and ticks, however many formulations are greasy, as well as some sensitive pets may have an allergic reaction to contact some of them. Many clients also worry about the exposure of humans to topical flea and tick pesticides. That is why the exciting new product from Merial known as Nexgard has been such a welcome addition to our flea and tick treatment and prevention options. By using a the ingredient, afoxolaner, Merial has come out with a new product that most fleas and ticks are certainly susceptible. Dogs also LOVE the soft, beef flavored chewable, even without meals. It has also been shown to be safe at up to 5 times the recommended dose.The only down side to this product is that the parasites must bite the dog to be affected, and in some cases this may take up to many hours for this to occur. However, studies as well as clinical experience with this product show that is it very effective in preventing Lyme, Anaplasmosis, Ehrlichiosis and Rocky Mountain spotted fever. This makes it essential as part of any year round parasite prevention program in our dogs. The only rare side effects I have seen are mild digestive upset. I therefore give this product an overall rating of a 4.5, with an ease of use of a 5 out of 5. |
