Vet Review | 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. | 1800petmeds is very excited to now offer an economic and reliable alternative to the brand name Front line plus in the war against flea and tick infestations on dogs and cats. By storing itself in the oil glands of the skin, the ingredients self distribute through the hair follicles and provide protection against fleas, ticks and lice for up to a month. While most of the competitors' products kill only the adult fleas on pets, the two main ingredients in this product, fiprinil and methoprene, not only kill the adult fleas and ticks, but also eggs and larvae, which may represent up to 95% of the total flea population. Recent studies in dogs have shown that these ingredients together start killing fleas within 4 hours, and within 12 to 24 hours 100% of the fleas are killed. While many competitors' products require the fleas to bite the pet, Flea 5x kills on contact. Another wonderful advantage of using Flea 5x is that the product is water proof, and will not be washed away with bathing or swimming, as long as animal guardians wait until the product is completely absorbed into the oil glands, which usually takes 48 hours, before bathing the pet or allowing pet to swim. Veterinarians and guardians should also know that this product is safe to use in breeding, pregnant and lactating dogs and cats. However kittens and puppies should be at least 8 weeks of age before applying this product. Because fleas and ticks pose many health threats to both dogs and cats, including dangerous anemia, rickettsial diseases, flea allergy dermatitis, and tapeworms, it is important to have all pets on a comprehensive flea and tick control program such as Flea 5x. And with the reliable 1800petmeds brand name, animal guardians can confidently rely on the performance of this product as comparable to the brand name. I see very few disadvantages in using this product. Rarely there may be a mild contact dermatitis at the site of application, where occasional pets experience crusting and hair loss. Even less common are idiosyncratic digestive or neurologic upset in very sensitive patients. Any pet with a chronic health condition or prior sensitivity to chemicals or vaccination should have a thorough veterinary exam and evaluation before applying any topical or oral pesticide product. I also recommend that the application of products such as Flea 5x be done on a different day(preferably at least 7 days apart) from other parasite control products such as heartworm prevention or immune challenges such as vaccination. Occasionally clients may see more fleas on their pets after immediately applying Flea 5x plus, but this is just the dying off of the flea population, as they rise to the top of the coat. Because of the often presence of eggs in the environment before the application of this product, it may take a few months to kill the total population of fleas in the home, which is why I often suggest treating the home as well when starting pets on a product like flea 5x plus. While flea 5x does not repel fleas and ticks, I have not found any current products on the market effective with that in my experience and opinion. I give this product an overall rating of 4.5(on scale of 1-5) with the efficacy and ease of use of a 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. |
