NexGard kills adult fleas and is indicated for the treatment and prevention of flea infestations (Ctenocephalides felis), and the treatment and control of Ixodes scapularis (black-legged tick), Dermacentor variabilis (American dog tick), Amblyomma americanum (lone star tick), Rhipicephalus sanguineus (brown dog tick), and Haemaphysalis longicornis (Longhorned tick) infestations in dogs and puppies 8 weeks of age and older, weighing 4 pounds of body weight or greater, for one month. NexGard is indicated for the prevention of Borrelia burgdorferi infections as a direct result of killing Ixodes scapularis vector ticks.
NexGard makes monthly dosing a rewarding, shared experience between pet owner and dog. Dogs prefer the beef-flavored flea and tick chew.3
NexGard chews can be administered with or without food. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes to ensure that part of the dose is not lost or refused. If it is suspected that any of the dose has been lost or if vomiting occurs within 2 hours of administration, re-dose with another full dose. If a dose is missed, administer a NexGard chew and resume a monthly dosing schedule.
Flea Treatment and Prevention: Treatment with NexGard chews may begin at any time of the year. In areas where fleas are common year-round, monthly treatment with NexGard chews should continue the entire year without interruption. To minimize the likelihood of flea reinfestation, it is important to treat all animals within a household with an approved flea control product.
Tick Treatment and Control: Treatment with NexGard may begin at any time of the year.
