Comfortis is an oral medication used for controlling and preventing flea infestations in canines and felines. The product takes effect within 30 minutes of administration and lasts an entire month. The tablets are available in 90mg, 140mg, 270mg, 560mg, 810mg, and 1620mg.
What the product cures
Comfortis can prevent/treat flea infestations, as well as decrease the risk of other conditions caused by fleas from developing.
Fleas are one of the most common parasites found in pets, mainly due to their adaptability and speedy reproduction cycle. They have the ability to leap up to 2 feet in the air, live for a year, and produce thousands of offspring. In dogs and in cats, the most common flea is the Ctenocephalides felis, but there are other flea species that can lead to an infestation.
Examining your pet’s skin/coat on a regular basis is one way to help prevent a flea infestation from developing. The tail, rear end, and neck are some of the areas where fleas are more likely to be seen. A flea comb can be used to provide a more thorough inspection and catch fleas (if present). During the exam, you can also check for “flea dirt,” which is a term used to describe dirt-like feces left behind by adult fleas that have been feeding off of your pet’s blood. Particles that look like grains of sand may also be detected; these are the flea eggs. Additional symptoms that may indicate flea presence or even an infestation include; skin inflammation, redness, scratching, chewing or licking affected areas, alopecia, and tapeworms, which separate into segments and are commonly described as rice-like.
Murine typhus, tapeworm infection, bartonella, anemia, flea allergy dermatitis, rocky mountain spotted fever, and Lyme disease are some of the ailments in dogs and cats related to flea infestation.
