What is Nexgard®?
Nexgard ® is an oral chewable tablet used to treat and prevent fleas and certain ticks in dogs. To prevent ticks, Nexgard ® is indicated for the treatment and control of American dog ticks, black legged ticks, solitary star ticks and brown dog ticks.
Nexgard® is also used as an additional name to treat demodicosis, sarcoptic mange and ear mites in dogs. In addition, it has also been used in cats to treat ear mites and fleas, pigs to treat scabies, and birds to treat bird lice. The term “extra labelled” or “unapproved use” means that a drug can be used in a way or in a particular species of animal that is not specified on the drug label. While vets often prescribe medications for additional use, your vet will decide whether this medication is right for your dog.
How Nexgard® works
The active ingredient in Nexgard ® is afoxolaner, which belongs to a newer class of flea and tick repellents called isoxazolines. Isoxazolines eliminate fleas and ticks by overwhelming their nervous systems, leading to paralysis and death.
Nexgard ® works within the first few hours after administration to kill fleas that are on your pet. It is dosed by weight for dogs, so it is important that you use the right size medication for your pet. Weighing your dog regularly ensures that you are using the correct size product.
Follow the instructions on the drug label or as directed by your vet. This medication is given orally once a month to dogs that weigh 4 pounds or more and are 8 weeks of age or older. You can give Nexgard ® with or without food. If your dog vomits this medication within two hours of administration, repeat the dose by chewing it all over again.
Have you missed a dose?
If you forget to give a dose of Nexgard ®, enter it when you remember and continue on a monthly dosing schedule. Do not give extra or double doses. If a long time has passed since the last dose, fleas may appear temporarily during the missed period.
