Precautions

  • The safe use of Comfortis in breeding, pregnant, or lactating cats has not been evaluated.

Mode of Action:

The primary target of action of Comfortis in insects is an activation of nicotinic acetylcholine receptors (nAChRs). Spinosad does not interact with known binding sites of other nicotinic or GABAergic insecticides such as neonicotinides, fiproles, milbemycins, avermectins, and cyclodienes. Insects treated with spinosad show involuntary muscle contractions and tremors resulting from activation of motor neurons. Prolonged spinosad-induced hyperexcitation results in prostration, paralysis, and flea death. The selective toxicity of spinosad between insects and vertebrates may be conferred by the differential sensitivity of the insect versus vertebrate nAChRs.

What are the potential side effects of Comfortis?

For cats: The most common adverse reaction recorded in clinical trials was vomiting. Other adverse reactions were: lethargy, decreased appetite, weight loss, and diarrhea. Use with caution with concomitant extra-label use of ivermectin.


Effectiveness

In a well-controlled laboratory study, Comfortis began to kill fleas 30 minutes after administration and demonstrated 98% effectiveness within 4 hours. Comfortis kills fleas before they can lay eggs. In a separate well-controlled laboratory study, Comfortis demonstrated 100% effectiveness on the first day following treatment and >90% effectiveness on Day 30.

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.

Instructions

Administer Comfortis with food for maximum effectiveness.

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 (spinosad) is available in four sizes of chewable flavored tablets for oral administration to cats and kittens according to their weight. Comfortis should be administered at monthly intervals.

Cat 1,9 to 2,8 kg BW 1 tab.140 mg 

Cat 2,9 to 3,6 kg BW 1 tab.180 mg 

Cat 3,7 to 5,4 kg BW 1 tab.270 mg  

Cat 5,5 to 8,5 kg BW 1 tab.425 mg


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.
