Dosage and Administration: for Dogs

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

Do not use the dosing schedule below when administering Comfortis to cats, as it can result in an underdosage.

*Dogs over 120 lbs should be administered the appropriate combination of tablets.

Administer Comfortis with food for maximum effectiveness

Comfortis is a chewable tablet and is readily consumed by dogs when offered by the owner just prior to 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 reinfestation, it is important to treat all animals within a household with an approved flea protection product.

Storage:

Effectiveness:

In a well-controlled laboratory study, Comfortis began to kill fleas 30 minutes after administration and demonstrated 100% effectiveness within 4 hours. Comfortis kill fleas before they can lay eggs. If a severe environmental infestation exists, fleas may persist for a period of time after dose administration due to the emergence of adult fleas from pupae already in the environment. In field studies conducted in households with existing flea infestations of varying severity, flea reductions of 98.0% to 99.8% were observed over the course of 3 monthly treatments with Comfortis. Dogs with signs of flea allergy dermatitis showed improvement in erythema, papules, scaling, alopecia, dermatitis/pyodermatitis and pruritus as a direct result of eliminating the fleas.
