Comfortis Basics

Q: What are Comfortis® (spinosad) tablets?

Comfortis is a beef-flavored tablet you give to your dog or cat to kill fleas and prevent flea infestations for one month. Comfortis chewable tablets are recommended for monthly use in dogs 3.3 pounds or greater, cats 2 pounds or greater and puppies and kittens 14 weeks and older.

Q: What is spinosad?

Spinosad is the active ingredient in Comfortis. It belongs to a new novel class of antiparasitics known as spinosyns, which are derived from a naturally-occurring soil microbe. It works by attacking the nervous system of insects, causing rapid death of adult fleas.

Q: How long does Comfortis last?

Comfortis has demonstrated full effectiveness for an entire month.1 View a short video testimonial about the many benefits Comfortis offers.

Q: When should treatment with Comfortis begin?

Treatment with Comfortis chewable tablets can begin at any time of the year. Comfortis is most effective when given one month before fleas become active and monthly dosing is continued through the end of the flea season. In areas where fleas are common year-round, monthly treatment with Comfortis chewable tablets should continue throughout the entire year without interruption. To minimize the likelihood of flea reinfestation, it is important for you to treat all animals in your household with a veterinarian-approved flea protection product.

My two dogs were having a dreadful time with fleas last year until I discovered Comfortis. Easy to use and very effective. The price from this website is excellent

I had been treating our cat with a topical flea product over the summer with little effect. I tried comfortis out of desperation after reading about it. Our cat just ate the tablet, no fuss. Within 2 hours the fleas were dropping off dead or dying. He was sitting on my knee and suddenly jumped up kicking and licking which went on for a couple of hours, all the while dead or dying fleas were appearing. We had our home sprayed for fleas the next day. It is so good to see him sleeping peacefully again.
