Treatment with NexGard may begin at any time of the year. In areas where fleas are common year-round, monthly treatment should continue the entire year without interruption.

If fleas or ticks are already present, discuss what other control measures should be used. Talk about what flea products to use on any other pets in the household, since all pets should be treated if there is an infestation. Have your veterinarian explain the life cycle of the flea and how that influences the effectiveness of monthly flea products.

NexGard should be used with caution in dogs with a history of seizures. The safety of NexGard has not been evaluated in pregnant, lactating or breeding dogs. Tell your veterinarian if your pet has epilepsy, could be pregnant, is lactating or is used for breeding.

As with any medication, notify your veterinarian of any other medications or supplements your pet is taking, and also if your pet has had any reactions to previous medications or supplements.

If you miss a dose, give it as soon as you remember, then resume giving it every 30 days (once a month). If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give 2 doses at once. If you are unsure whether to give a dose, contact your veterinarian.

Not for use in animals hypersensitive (allergic) to afoxolaner. Use with caution in dogs with a history of seizures. Consult your veterinarian before using NexGard in breeding, pregnant or lactating dogs (female animals nursing their young).
