Before giving NexGard to your dog, talk to your veterinarian about your dog’s health history, current medications, and any previous reactions to flea or tick products.
Neurologic Side Effects
NexGard belongs to the isoxazoline class of flea and tick medications. In rare cases, medications in this class have been associated with neurologic side effects, including tremors, loss of coordination (ataxia), and seizures.
Use NexGard with caution in dogs that have a history of seizures or neurologic disorders. Contact your veterinarian right away if your dog develops shaking, stumbling, weakness, unusual behavior, or seizure-like activity after taking NexGard.
Pregnancy, Breeding, and Lactation
The safe use of NexGard has not been evaluated in pregnant, breeding, or lactating dogs. If your dog is pregnant, nursing, or intended for breeding, speak with your veterinarian before using NexGard. Your veterinarian can help decide whether NexGard is appropriate or whether another flea and tick prevention option may be safer.
Missed, Lost, or Vomited Dose
Give NexGard exactly as prescribed based on your dog’s current body weight. If a dose is missed, give the usual dose as soon as you remember, then continue with the regular once-monthly dosing schedule.
If you think the dose was lost, not fully swallowed, or if your dog vomits within 2 hours of taking NexGard, contact your veterinarian. Another full dose may be recommended depending on the situation.
Follow Weight-Based Dosing
NexGard dosing is based on your dog’s weight. Do not split, adjust, or give extra doses unless your veterinarian tells you to do so. Giving the wrong dose may reduce protection or increase the risk of side effects.
Important Reminder
NexGard is for dogs only and should be used under veterinary guidance. Keep the chewables out of reach of children and other pets, and contact your veterinarian if you notice any unusual symptoms after administration.
