FLEA MEDICINE FOR DOGS AND CATS THAT STARTS KILLING FLEAS IN JUST 30 MINUTES
Comfortis® (spinosad) is a fast, safe and effective flea treatment for flea infestations on your dog or cat. It starts killing fleas faster than Nexgard® (afoxolaner)3,* and killed 100% of fleas on dogs and 98% of fleas on cats in just four hours in controlled laboratory studies.
*Data from two laboratory studies conducted in different locations using different dogs and strains of fleas.
The worst part of a flea infestation is not what you can see—it's what you can't. Microscopic flea eggs, larvae and pupae can permeate your home and keep the flea infestation cycle going. Comfortis kills fleas before they lay eggs and keeps killing fleas for a full month with each dose. Use Comfortis for at least three months to treat a current flea infestation, then continue routine use to prevent a re-infestation on your pet. In a field study conducted in households with existing flea infestations in dogs, flea count reductions of 97.9% were observed one month after the first treatment and 99.9% after three monthly treatments with Comfortis.4
When you want to get rid of fleas, choose Comfortis. It’s the brand trusted by veterinarians, prescribed more than 80 million times.5
Comfortis is approved for use in cats 14 weeks of age or older and 4.1 pounds of body weight or greater and dogs 14 weeks of age or older and 5.0 pounds of body weight or greater.
