Comfortis® (Spinosad) Receives Approval for Flea Control in Cats and Small Dogs

    GREENVILLE, Indiana, August 24, 2012—Comfortis® (spinosad), approved for flea control in some dogs since 2007 has now been approved for use in cats and smaller dogs. As a result of the recent FDA approval, Comfortis can now be used in cats and kittens greater than 2 lbs and 14 weeks and older. In addition, the new 90 mg tablet will allow veterinarians to prescribe Comfortis for smaller dogs weighing 3.3–4.9 lbs and 14 weeks and older.

    “Veterinarians have been requesting that Comfortis be approved in cats and smaller dogs since it launched,” said Stephen Connell, DVM, director, technical, academic, and consumer services at Elanco Companion Animal Health. “Comfortis is ideal for pet owners who have an immediate need for flea control due to its fast speed of kill,” Connell added. “It is also a solution for pet owners who are concerned about their children or other pets being exposed to topicals, have pets that are bathed or groomed frequently, or are concerned about topicals rubbing off on furniture and carpeting.”

    • Starts killing fleas in 30 minutes
    • Kills fleas before they lay eggs
    • Lasts a full month
    • Can’t be washed, rubbed or groomed off

    In addition to providing effective flea control, Comfortis features product tracking, designed to help keep Comfortis within the context of the veterinary/client/patient relationship. Every box and carton of Comfortis can be tracked from manufacturer to distributor to clinic. Elanco proactively purchases products found in non-veterinary channels and investigates the source of diverted products; monitors abnormal clinic purchasing activity; and constantly evaluates new ways to identify and stop diverters. More than 400 veterinarians have been permanently banned from purchasing Elanco companion animal products as a result of being caught diverting products.

    With this FDA approval, Comfortis is labeled for use in both cats and dogs. The new 90 mg tablet for cats (2–4 lbs) and dogs (3.3–4.9 lbs) is now available to veterinarians. Veterinarians seeking more information about Comfortis may contact their Elanco representative, distributor representative, or call 888-545-5973.
