NexGard Basics

NexGard is available by prescription only. It is used once monthly to treat and prevent infestations of fleas, american dog ticks, black-legged ticks, brown dog ticks, and lone star ticks. It is for use in dogs and puppies that are 8 weeks of age and older and weigh more than 4 pounds. The active ingredient in NexGard is afoxolaner. Afoxolaner blocks the transfer of chloride ions in insect cells, attacking the central nervous system of fleas and ticks. This product comes in easy to administer, beef-flavored chews. It comes in the following sizes based on your pet’s weight:

  • 4 – 10 lbs (Orange Box)
  • 10.1 – 24 lbs (Blue Box)
  • 24.1 – 60 lbs (Purple Box)
  • 60.1 – 121 lbs (Red Box)

NexGard Directions

Use as directed by your veterinarian, and always follow the instructions printed on the prescription label. Give 1 tablet by mouth once a month. For pets weighing over 121 pounds, give two chews equaling the appropriate weight of the pet. This medication can be given with or without food.

Store at room temperature, protected from light and moisture.
