How Nexgard Spectra Works?

Nexgard Spectra for dogs contains Afoxolaner and Milbemycin oxime as active ingredients. Both the active ingredients of Nexgard Spectra act by interrupting the neurotransmission in the nervous system of the parasites causing paralysis and death of the organisms.

Important Note: Merial is now acquired by Boehringer Ingelheim. So, the manufacturer’s name on product packs may vary according to the available stock.

Ingredients: Afoxolaner, Milbemycin Oxime
