Comfortis for Dogs & Cats - 1800PetMeds
Capstar flea medication begins to kill fleas within 30 minutes of dosing. Within 6-7 hours of dosing, 100% of adult, blood sucking fleas present on the animal's body will be dead. New fleas will of course jump onto your pet's body from the environment and the Capstar flea medication will get rid of these fleas very well for 24 hours after dosing (a 2003 study in the Journal of Medical Entomology showed that Nitenpyram actually maintained high effectiveness for up to 48 hours, though pills are generally administered daily). Capstar is excreted rapidly from the body via the urine and once-daily dosing is required if one is to maintain nitenpyram's excellent flea killing effect (should Capstar flea medication be the only treatment elected for that animal).
A 2008 study, published in the journal of Veterinary Parasitology, examined the effect of various flea control products, including Capstar flea medication, on flea feeding times and blood consumption quantities. The first thing noticed in the study was that 38% of fleas were dead within 1 hour of nitenpyram (Capstar flea pills) dosing and that 100% had died or were dying within 4 hours of dosing (again - fast acting). Capstar flea control pills also caused significant reduction in blood consumption by fleas. Nitenpyram-affected fleas only fed for about 15 minutes before starting to die. Only topical selamectin (Revolution) was found to be similar in its ability to greatly limit flea feeding times and blood consumption. Note that Spinosad (Comfortis) was not around when this study was conducted so wasn't compared at this time. The abstract ends by stating: "In this study systemically acting insecticides such as nitenpyram, and the topically applied but systemically active insecticide selamectin, were more effective in interfering with flea blood feeding than were imidacloprid and fipronil."
Many people use as an alternative to other flea prevention products, like flea drops or flea collars. As with most other products used for flea control, there are several types of pills that have different purposes. Some flea pills only kill the adult fleas and some hits the fleas on every stage in . There are also different types of flea pills for dogs and cats that are given either monthly or daily. Most of the pills for dogs are dangerous for cats, so be sure you get the correct product for your pet.You have to decide whether you want to give your dog or cat daily or monthly flea pills. Usually the monthly pills are meant to keep the larvae and eggs from developing into adult fleas. This is great for preventing fleas, but if your pet already has fleas, you want to get them off as fast as possible. This is where the daily pills excel, killing every living adult flea within a day or so. This pill combined with general could be enough to get rid of your flea problem, if your pet spends all its time indoors. If this was the case though, you probably wouldn’t have a flea problem in the first place. If you want to prevent fleas with flea pills, I recommend you use the monthly pills for longer term use. It’s easier to administer and the total protection level is much higher than with a daily flea pill.I recommend that you get flea pills that treat and prevent fleas on every stage, including eggs, larvae and adult fleas. One female flea produces thirty or more eggs a day, so even if you kill all the adult fleas, you are still left with lots of eggs that are just waiting to hatch. Compare the different flea pills to each other and find the ones that are best suited for your pet. As with medication for humans, some might not work on your pet even though they work on others. I believe it’s always better to start with smaller amounts and see if they work, as you have to remember that you are dealing with medicine designed to kill small organisms, and some pets may get allergic reactions to different kinds of flea control products.Comfortis is a 30 day pill that gets rid of fleas by killing the adults and breaking the flea cycle. It was approved in August 2012 for use in cats but word has been slow to get out.
