NexGard Chewables for Dogs

Eliminating your dog’s fleas and ticks is essential to keeping your pet safe from biting pests and all the threats they pose to your entire household -- from persistent itchiness and allergic reactions to potentially fatal pest-borne illnesses like Lyme disease.

The active ingredient in NexGard, afoxolaner, works on the nervous system of fleas and ticks, causing hyperexcitation and death.

NexGard is a soft chewable that is given orally and can be given with or without food.

NexGard kills adult fleas and is indicated for the treatment and prevention of flea infestations (Ctenocephalides felis) and the treatment and control of American Dog Tick infestations (Dermacentor variabilis) in dogs.

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. To minimize the likelihood of flea reinfestation, it is important to treat all animals within the household (along with the environment) with an approved flea product.

NexGard comes in a beef-flavored soft chewable.

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).

May see vomiting, dry/flaky skin, diarrhea, lethargy or lack of appetite. Consult your veterinarian if you notice any of the above side effects.

If your pet experiences an allergic reaction to the medication, signs may include facial swelling, hives, scratching, sudden onset of diarrhea, vomiting, shock, seizures, pale gums, cold limbs, or coma. If you observe any of these signs, contact your veterinarian immediately.

Store at or below 86 degrees Farenheit. Keep out of reach of children and pets.
