Vet Review | Certifect is the new flea and tick control product by Merial, the makers of Frontline® Plus. It is EPA-approved for sale in the USA. It is new to the market and not yet rated. | One of my favorite and most widely prescribed flea and tick control products in practice front line top spot offers not only the ease of application in one spot, where it collects in the hair follicles and skin oils and gradually released over the month, but also a wide area of safety in most pets, including breeding, pregnant and lactating dogs. . It will kill adult fleas and larvae by selectively affecting the parasite's nervous system. Efficacy against flea eggs is variable in my experience and opinion. It will also kill chewing lice and some veterinarians, including myself have seen it work to help control demodectic mange and ear mites, although it is it not approved for use for these uses. This versatile product will also kill all stages of various ticks including brown dog ticks, american dog ticks, lone star ticks and deer ticks. I have also used it to control sarcoptic mange infestations in dogs, but will often go to topical revolution first in sarcoptic mange or ivermectin as my first choices for scabies. In general I find that fleas and ticks are generally killed before they have the chance to transmit diseases in patients, usually being close to 100% effective within 24 to 48 hours. The formulation is water proof so it is certainly appropriate to use in those outdoor dogs who love to swim. I have only seen occasional/rare side effects at the sight of application, and even more rare systemic reactions like digestive upset or neurological reactions or blood disorders in extremely sensitive pets. However these reactions are rare in my experience. In geriatric patients or sick patients or those with chronic disease it is important to consult with your veterinarian before applying this or any other topical flea and tick product. | Because of the difficulty for some clients in getting their cats to take pills, the development of this flavorable suspension to mix easily with their wet food has made compliance and efficacy of flea control a lot easier. Getting felines to take medication can always be a challenge. When not accepted in food, many clients have found mixing in various tuna or clam juices, oil, broth, gravy or sardines another way of administering this and other medications. As mentioned in my product review on program tablets, this product works best when given with meals for maximal absorption as well as before fleas are firmly established on the pet and in the home. It works by preventing development of flea eggs and larvae by in essence sterilizing the adult fleas who happen to bite the animal. The product does not kill existing adult fleas and must be combined with other products like Capstar or topical Advantage or Frontline in pets with active flea populations. I find it works best as a preventative before flea season. Many clients will chose to use this and other flea products year round due to the warming of the climate and the unpredictability of the flea season. I give this product an overall rating of a 4 with an ease of use and taste a 5 and efficacy a 4. |
