Comfortis is a monthly flea control treatment for dogs. It kills fleas rapidly and controls flea infestation for one month. The beef-flavored tab destroys adult fleas before they lay eggs. Comfortis comes in a convenient chewable tab for monthly flea treatment. The fast-acting formula starts working within 30 minutes and prevents further flea infestation. It controls flea borne diseases and protects dogs from fleas for full one month.
Comfortis can be given to dogs at least 14 weeks of age.
How it works?
Comfortis contains Spinosad. This active ingredient causes involuntary muscle contractions and tremors resulting from activation of motor neurons. Prolonged spinosad-induced hyperexcitation results in prostration, paralysis, and flea death. The oral tab protects dogs and puppies from harmful flea bites and flea allergy dermatitis.
