Can a dog have a seizure after taking NexGard, and if so, how soon might it happen?

Yesterday, I gave my dog NexGard for the first time, as advised by our vet. Since then, I've been nervous after hearing some stories about seizures occurring in dogs after taking it. Could you tell me if there's a chance my dog might have a seizure from NexGard, and if so, how soon after taking it might this occur?

Answer

NexGard is a commonly used and generally safe oral flea and tick preventative, but there have been some reports of neurological side effects including seizures in some dogs.

  • Monitor your dog for any unusual behavior or seizures following administration.
  • Common side effects are generally mild, such as vomiting or diarrhea.
  • More serious side effects can include neurological issues like seizures, though these are rare.

It’s important to consider that while these side effects are possible, they are not common and the benefits of preventing flea and tick-borne illnesses are significant. If you notice any concerning symptoms, contact your veterinarian immediately. Additionally, your veterinarian can discuss any potential risks based on your dog's unique health history.
