Afoxolaner (INN)[2] is an insecticide and acaricide used in dogs. It is indicated for the treatment and prevention of flea infestations, and the treatment and control of tick infestations in dogs and puppies 8 weeks of age and older, weighing 4 pounds (~1.8 kilograms) of body weight or greater. It is given once a month.[3]
Unlike most other flea treatments which are applied topically to the animal's coat, afoxolaner is administered orally in meat-flavoured tablets, and poisons fleas once they start feeding. It is used either alone or as a combination treatment with milbemycin oxime.[4][5][6]
