My dog has epilepsy. Is Bravecto safe? What are the seizure risks?

Updated on September 23rd, 2025

Pet's info: Dog | Maltese | Female | unspayed | 7 years and 7 months old

I just bought Bravecto for my dog. She has epilepsy and I mentioned this to the vet. She said bravecto can still be used but with caution. My dog doesn't have seizures often, maybe once a year from what I have noticed. Do you think I should still give my dog Bravecto? Will her seizures be more severe or what are the risks giving it to a dog with epilepsy? Death?

There are less than a handful of cases of dogs that had break-through seizures some time after given Bravecto. However, unlike other products (i.e. Comfortis, Trifexis), Bravecto has NOT been proven to increase the seizure threshold. Many many pets do well on it and therefore it has been considered relatively safe across the board. Seizures rarely cause death in pets fortunately if Bonita does happen to have a break-through seizure. Report any adverse events to your veterinarian. Also, keep in mind that pets that have seizures and are on anti-seizure medication, can still have seizures but they should not be frequent (less than 1 per calendar month) and should not last more than 3-5 mins in duration.

Best wishes with your pet Bonita moving forward. Take care! : )

    Thanks for using Petco Pet Education Center, formerly Petcoach! Every medication has side effects and seizures is a side effect of this medication. It is mostly seen in unhealthy pets or dogs that already have seizures. If your pets are healthy and don’t have seizures, I wouldn’t be concerned. Kisses to your pups!
