Is Trifexis Killing Our Dogs?

BY:  Laurie Brzostowski, President, Snaggle Foot Dog Walks and Pet Care-Round Lake, IL

There has been a lot of news lately about dogs dying after being given Trifexis.  This is very sad.

Because it is so sad I thought I would do some research on this particular drug and get some facts for everyone.

What is Trifexis?
Trifexis, a flea killer and heartworm preventive was introduced in 2011. Trifexis, a beef-flavored chewable tablet, is available in five dosages based on a dog’s weight. The drug is indicated to prevent and treat flea infestations, prevent heartworm disease, and treat and control adult hookworms, roundworms and whipworms.

This particular drug is being blamed for nearly 1,000 dog deaths, but both the manufacturer and the U.S. Food and Drug Administration cautioned that no evidence has been found tying the drug to the claims.

Pet owners have debated the drug’s safety on multiple websites and even started a Facebook page called Does Trifexis Kill Dogs?

FDA, which approves and regulates human and animal drugs, acknowledged that dog owners and veterinarians have lodged formal complaints about Trifexis (spinosad and milbemycin oxime).

“FDA is aware of adverse event reports in connection with Trifexis and continues to closely monitor them,” the agency reported in a prepared statement. “It is very important to realize that reports of adverse events do not necessarily mean that the product caused the event. Other factors, such as existing disease, exposure to chemicals or contaminants, foods, or other medications may have triggered or contributed to the cause of the event.”

The drug’s manufacturer in March 2012 added ataxia and seizures to the list of reported adverse reactions. The drug’s initial approval noted mild side effects such as vomiting, itching, lethargy and diarrhea.

Dog owners should raise any concerns about Trifexis with their veterinarian and any pet owners who have had problems they believe are attributable to any FDA-regulated products to work with their veterinarians to file a report with the agency.

What Should You Do?
If you have had issues with this drug it is important to notify the FDA and file a report.  You can do so at this link:  http://www.fda.gov/AnimalVeterinary/SafetyHealth/ReportaProblem/ucm055305.htm

Let's make sure our pets are kept safe and if you are not comfortable giving your dog this medication, then don't do it.
