Method of working
Nexgard contains afoxolaner as the active ingredient. Afoxolaner keeps releasing for one continuous month. It creates hyper excitation in the central nervous system of fleas and ticks, and destroys them. The continued activity for 30 days prevents any chances of re-infestations. Additionally, flea tapeworm infestation is prevented by the action of afoxolaner on the primary intermediate host, the flea. The active ingredient rapidly kills fleas, which effectively prevents maturation of the immature stage of tapeworms, and thereby prevents flea tapeworm infestations in dogs. The treatment is highly effective for Paralysis ticks, Brown dog ticks and Bush ticks. The flavoured chewable reduces flea egg production and flea population. It is safe to use on puppies from 8 weeks of age.
