How does Comfortis work?

The active ingredient in Comfortis, spinosad, works on the nervous system of a flea, causing paralysis and death.

Is there a generic equivalent available?


How is it given?

Comfortis is a chewable tablet that is given orally with food for maximum effectiveness. If vomiting occurs within one hour of administration, redose with another full dose.

Comfortis is preferably started one month before fleas become active and should be given monthly through the end of the flea season. In areas where fleas are common year-round, monthly treatment should continue the entire year without interruption.

This medication should only be given to the pet for whom it was prescribed.

What results can I expect?

Comfortis will start to kill fleas within 30 minutes and it should remain effective for one month. If the pet was already infested with fleas when Comfortis was given, you may see fleas after that period of time as the immature forms of the fleas in the environment hatch.

What form(s) does it come in?

Comfortis comes in a chewable tablet form.
