Vet Review | 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 is one of my favorite and most effective products in preventing tick infestations on dogs of all sizes, as well as preventing the tick born diseases such as Lyme disease, Rocky Mountain Spotted Fever, Ehlrichia and Anaplasmosis. When some of the topical products have failed in some patients, I have found this collar quite valuable in significantly cutting down on tick burdens in these dogs. The effects are long lasting for up to 3 months preventing ticks from even attaching to dogs, and thus cutting down on tick exposure to humans as well. The only problems in terms of efficacy I have even seen with this product is when animal guardians apply the collar too loosely to their pets, which can cut down on its efficacy against ticks.. In order for this collar to work effectively, it must be fitted snugly against the pet's neck, where one is just able to get two fingers under the collar. If the collar is applied too loosely I have occasionally seen pets ingest this collar, leading to serious systemic reactions. The only other downside in using this collar is if the pet spends a significant time swimming during the warmer months. The collar's efficacy is cut down significantly if it is submerged in water or exposed to drenching rains. However when properly fitted to a dog's neck, this is one of the most effective products in preventing tick infestations on the market. | Sentinel is a wonderful combination of the heartworm prevention pill interceptor and the flea control product program both in this one pill. Many clients enjoy the convenience of having such broad acting internal and external parasites in one pill, without having to worry about giving two separate medicines. Lufenuron, which is the main flea control ingredient, stops the flea life cycle in its track at the egg and larval stage, thus being like a birth control pill for fleas who get on our pets. Given that the main problem of fleas is how rapidly they reproduce, this pill literally stops escalating growth of flea populations, before they can become established in our homes, where most of the flea life cycle occurs. The main disadvantage to this product is that it does not kill or repel adult fleas, so in situations with already established heavy infestations, it is best combined with a great topical product like advantage or front line or with the oral adulticide flea pill Capstar for maximal effect. The only other rare disadvantage I see is the slight increase in reactions when two products are combined into one like this, but fortunately this is not common in clinical practice. With milbemycin for prevention of heartworms and controlling and treating most common intestinal worms, I overall highly recommend this versatile product. |
