About Comfortis For Dogs - Monthly Flea Control Pill
There have been a few oral flea control products that have come out in the past,
including Capstar, Sentinel and Program. However, the comfortis flea pill
is the first one that kills adult fleas for an entire month.
Program and Sentinel are also oral flea meds, however, they are designed to
kill fleas in the larvae and pupae stages only - they do not kill adult fleas
like Comfortis does. Comfortis flea is just the opposite, it kills fleas
in the adult stages only and will not prevent the hatching and growth of larvae.
Like Comfortis, Capstar is also a chewable given by mouth. But capstar flea killer only acts on fleas
that are on the dog at the time the pill is given. Capstar does not offer the month
long residual effect that Comfortis does.
Comfortis, made by the pharmaceutical company Eli Lilly, contains the ingredient Spinosad which
works by circulating within the dog's bloodstream where it targets the biting flea's
nervous system to cause paralysis and death - but without having the same
effect on the dog's nervous system as it does on the biting flea itself.
