Vet Review | 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. | Parastar Plus combines the proven performing main ingredient of fipronil with cyphenothrin, which allows for more rapid killing and treatment of fleas, ticks, certain mites, and lice. This combination allows for this topically applied product to begin killing within an hour. In my experience, most of my clients have reported higher efficacy and better satisfaction for tick control over fleas. It seems to be easier to dispense out of the applicator over competitor products, and especially with lighter colored dogs the product does not seem to stain. However on occasion, I have seen a sensitive darker coated dog have some mild bleaching at the site of application. With some longer haired dogs, I have seen it leave an occasional slightly sticky spot at the site of application as well. Like many of the competitor products, it is touted as waterproof, however, I try and recommend that clients do not bathe dogs for 2 or 3 days before or after application, as some feel that this may affect the efficacy of the product. In my experience, I have found that this product is better at preventing problems rather than controlling already heavy flea infestations, in which case I usually will go to one of the newer oral tablets for flea/tick control that usually kill rapidly within 30 minutes. Another limitation of the product is that you can't use Parastar Plus on less than 4-pound dogs, which is an added benefit of topical prescription products like Revolution. As with any product of this type, occasional itchiness, and/or irritation/agitation from applying the product may be seen, but I find this side effect less common than with competitor products. It is also important for clients to understand that it is critical, especially with heavy flea infestations, to also focus on treating the environment as well. Overall this product has performed better for tick control and prevention than for fleas. I give it an overall rating of a 3, with an ease-of-application rating of 4.5 out of 5. | This versatile topical product has the widest range of protection of both internal and external parasites. In both cats and dogs, all 3 stages of the flea life cycle are effectively controlled,in addition to ear mites. For dogs, there is also the wonderful treatment benefit of killing hidden scabies mites on the skin, which are so difficult for veterinarians to find on routine skin scrapings at our offices. In fact, when either I or veterinary dermatologists are presented with a very itchy dog, in addition to our allergy workups, we will often treat with this topical every few weeks to treat and rule out any hidden scabies mites contributing to the pet's itching. It is amazing how many dogs will respond to this treatment, leading me to believe that scabies mites are involved with a lot more itching problems in dogs than I first learned about in vet school. With the increased recognition and understanding of feline heartworm disease, this is often the first heartworm preventative that I will reach for in cats, especially given all of the other benefits above. While it is often effective for canine heartworm prevention as well, I have heard of rare lapses in protection, so I usually combine this topical in dogs with one of the oral heartworm prevention medications like Heartgard or Interceptor. The only disadvantage I have seen is the rare reaction on cats of mild digestive upset and temporary hair loss at the site of application. It also has the wonderful benefits of being water proof in only 2 hours after application, and in being approved for use in puppies as young as 6 weeks of age. |
