Does Bravecto Flea and Tick Treatment Cause Seizures in Dogs?

Bravetco Flea and Tick Treatment causes seizures in dogs

Flea and tick control is an essential part of keeping our furry friends healthy and comfortable. However, for dogs with epilepsy, the choice of treatment requires careful consideration. One popular product, Bravecto, has gained attention in recent years, with concerns raised about its potential link to seizures in dogs. In this blog post, we delve into the topic and explore the relationship between Bravecto flea and tick treatment and seizures in dogs with epilepsy.

Toxicity Risks for Dogs with Epilepsy

It's important to note that not all flea and tick treatments are suitable for dogs with epilepsy. Many conventional flea and tick control products contain chemicals that can potentially trigger seizures or interact with anti-epileptic medications. Certain active ingredients, such as pyrethroids or organophosphates, have been associated with neurological side effects in dogs. Therefore, it is crucial to prioritize the safety of your epileptic dog when selecting a treatment option.

The Concerns Surrounding Bravecto

Bravecto is an oral medication that provides extended protection against fleas and ticks. While it is generally considered safe for most dogs, there have been reports and concerns regarding its potential association with seizures. It's important to emphasize that the incidence of seizures associated with Bravecto appears to be rare, but the main concern is that Bravetco tablets contain Isoxazoline.

Mechanism of Action

Isoxazoline acts on specific receptors in the nervous system of ticks and fleas, known as the gamma-aminobutyric acid (GABA) receptors and glutamate-gated chloride channels (GluCl). By binding to these receptors, isoxazoline interferes with the normal transmission of nerve signals, leading to hyperexcitation and ultimately causing paralysis and death of the parasites.

Potential Impact on the Dog's Nervous System

While isoxazoline is generally safe and effective for most dogs, it's important to understand that this class of medications can also interact with the dog's nervous system. Although the mode of action of isoxazoline primarily targets the nervous system of parasites, it can have some impact on the dog's nervous system as well.

The the US Food and Drug Administration has issued the following public notice about Isoxazoline:

  • Isoxazoline products have been associated with neurologic adverse reactions, including muscle tremors, ataxia, and seizures in some dogs and cats

  • Although most dogs and cats haven’t had neurologic adverse reactions, seizures may occur in animals without a prior history

  • The FDA considers products in the isoxazoline class to be safe and effective for dogs and cats but is providing this information so that pet owners and veterinarians can take it into consideration when choosing flea and tick products for their pets

Discussing Treatment Options with Your Veterinarian

When it comes to choosing the right flea and tick treatment for your dog with epilepsy, it's essential to consult with your veterinarian. They have the expertise and knowledge to assess your dog's individual needs, consider any potential drug interactions, and recommend the most suitable options. Your veterinarian will take into account your dog's medical history, current medications, and overall health to ensure the safety and well-being of your furry companion.
