Nexgard Spectra Chewable Tablets are used for the treatment of flea and tick infestations in dogs when the concurrent prevention of heartworm disease and/or treatment of gastrointestinal nematode infestations is indicated.
Nexgard Spectra Tablets have an efficacy against flea infestations for up to 5 weeks and against tick infestations for up to 4 weeks. Nexgard Spectra kills parasites by interfering with the way that signals are passed between the nerve cells of their nervous system, resulting in paralysis and death of the parasitic organism.
Nexgard Spectra Tablets are presented as mottled red to reddish brown circular (Extra Small Dog) or rectangular shaped chewable tablets (Larger strengths).
A Veterinary Prescription is required for Nexgard Spectra
