Comfortis is a chewable medication prescribed by veterinarians for dogs and cats to help treat -- and possibly even prevent -- flea infestations for up to one month. These flavored tablets can be added to your pet's favorite food and only need to be given to your canine companion once a month to help combat fleas.
Possible Side Effects
The most common side effect reported in dogs is vomiting.
Dose varies based on pet's weight. Use according to your veterinarian's instructions. Comfortis is generally given once a month, but you should always follow your veterinarian's directions. It is recommended to give Comfortis chewable tablets with food.
