Product Description

Trifexis (spinosad + milbemycin oxime) is the monthly, beef-flavored tablet that kills fleas and prevents flea infestations, prevents heartworm disease, and treats and controls adult hookworm, roundworm and whipworm infections. Trifexis is approved for use in dogs and puppies 8 weeks of age or older and 5 pounds of body weight or greater.

Trifexis is a prescribed pet medication for the prevention of fleas and parasites such as roundworm, hookworm and heartworm. Follow your veterinarian's directions on when to give this medication. If you are advised to give it seasonally for heartworm prevention, remember to give it during the mosquito season and 3 months beyond, preferably on the same date each month.

Trifexis should be used as recommended by your veterinarian. If you have difficulty giving the medication to your dog, contact your veterinarian.
