Product description

Comfortis is a once-a-month chewable tablet for the treatment and prevention of flea infestations in dogs.

Active ingredients

Each Comfortis chewable flavored tablet is formulated to provide:

  • minimum spinosad dosage of 13.5 mg/lb (30 mg/kg)

Indications for use

Comfortis kills fleas and is indicated for the prevention and treatment of flea infestations (Ctenocephalides felis) for one month, on dogs and puppies 14 weeks of age and older and 5.0 pounds of body weight or greater and on cats and kittens 14 weeks of age and older and 4.1 pounds of body weight or greater.

Administration and dosage

  • Comfortis is a chewable tablet that can be consumed by cats when offered by the owner just prior to or after feeding. Alternatively, Comfortis may be offered in food or administered like other tablet medications. Comfortis should be administered at monthly intervals.

  • If vomiting occurs within an hour of administration, redose with another full dose. If a dose is missed, administer Comfortis with food and resume a monthly dosing schedule.

  • Treatment with Comfortis may begin at any time of the year, preferably starting one month before fleas become active and continuing monthly through the end of flea season. In areas where fleas are common year-round, monthly treatment with Comfortis should continue the entire year without interruption.

To minimize the likelihood of flea reinfestations, it is important to treat all animals within a household with an approved flea protection product.

Comfortis for dogs:

Comfortis is given orally once a month, at the recommended minimum dosage of 13.5 mg/lb (30 mg/kg).
