Product Detail: NexGard Spectra

NexGard Spectra

Get adequate treatment and prevention of flea infestations, control of ticks and mites, prevention of heartworm, and treatment and control of intestinal worms in dogs and puppies from 8 weeks of age with NexGard Spectra. NexGard Spectra rapidly kills adult fleas and is indicated for the treatment and prevention of flea (Ctenocephalides spp.) infestations, for the control of newly acquired adult fleas, and for the control of Flea Allergy Dermatitis (FAD). Following administration, fleas are killed within 6-8 hours. Rapid onset of action kills newly acquired fleas before they can lay eggs. Fleas can transmit flea tapeworm (Dipylidium caninum). 


How NexGard Spectra works

NexGard Spectra paralyzes parasitic organisms by interfering with the way signals are passed between nerve cells (neurotransmission) in the nervous system of parasites that live in the fur of animals, such as fleas and ticks, and then kills it. Afoxolaner kills fleas before they can lay eggs and so helps to reduce contamination of the dog's environment.

Effective flea control with NexGard Spectra prevents flea tapeworm infestation in dogs. NexGard Spectra treats and controls Paralysis ticks (Ixodes holocyclus), Brown Dog ticks (Rhipicephalus sanguineus), and Bush ticks (Haemaphysalis longicornis) for one month. NexGard Spectra provides effective control of pre-existing Paralysis tick infestations within 24 hours. Ixodes holocyclus ticks do not occur in Western Australia. In tick season, daily searching for, and removal of, any ticks found is recommended. NexGard Spectra treats and controls demodectic mange caused by Demodex spp., sarcoptic mange caused by Sarcoptes scabiei, and ear mite (Otodectes cynotis) infestations. NexGard Spectra prevents heartworm disease caused by Dirofilaria immitis and treats and controls roundworms (Toxocara canis and Toxascaris leonina), hookworms (Ancylostoma caninum and A. ceylanicum) and whipworms (Trichuris vulpis).
