Is Bravecto Killing Dogs?

Is Bravecto Killing Dogs?

Recent news stories have implicated Bravecto in the deaths of many dogs.

This is unfortunate as we have prescribed over 4000 doses of Bravecto without a major incident. Many of our staff and veterinarians use Bravecto for their own dogs. We love that it’s a very effective flea and tick preventative, killing ticks faster than most other preventatives and thus leading to a much lower incidence of diseases (Babesia, Anaplasmosis, Lyme disease, and Ehrlichia) spread by ticks.

We have, from time to time, have owners tell us that their dog vomited the medication, but none have become ill and certainly none have died due to Bravecto. Like every other oral flea/tick preventative (Comfortis, Trifexis, and Simparica), dogs with a history of neurological disease (such as epilepsy) should not consume Bravecto. With the dogs that died after consuming Bravecto, there’s no knowledge of underlying neurological disease or severe liver disease that Bravecto may have potentiated. Nor do we have a pathology report to verify a relationship between the consumption of Bravecto and the dogs’ deaths.

As a whole, Merck has prescribed 34 million doses with serious adverse reactions very rare – less than .01 percent.

Bravecto is not an unregulated medication. This is an FDA approved medication that’s heavily monitored. Merck says that if a label change was necessary, the company would be first to recommend it.

As of right now, there’s no reason to suspect that Bravecto is killing dogs. Below is the study for the FDA approval of Bravecto with the group of dogs receiving Bravecto and the control group dogs receiving a placebo. Please use studies like this to make up your mind whether Bravecto is killing dogs.
