Ingredients

NexGard Spectra contains the following active ingredients: Afoxolaner and Milbemycin Oxime.

Afoxolaner is an ectoparasiticide, meaning it targets external parasites such as fleas, ticks, and mites. It effectively kills fleas before they can lay eggs, helping to reduce contamination of the dog's environment. Afoxolaner is also highly effective against various types of ticks, including paralysis ticks, bush ticks, and brown dog ticks.

Milbemycin Oxime serves as an endo parasiticide, targeting internal parasites such as worms that reside inside dogs. It is effective against different types of worms, including roundworms, hookworms, and whipworms. Milbemycin Oxime helps in preventing and controlling these internal parasites in dogs.
