FDA: Some flea and tick medications can increase seizure risk in pets

When it comes to pets, we try to do everything we can to protect them. But, did you know that dogs and cats that are treated with certain flea and tick products might be at an increased risk for neurologic events, including seizures?

The warning applies to drugs in the isoxazoline class, the FDA said.

The FDA monitors adverse drug event reports received from the public or veterinarians, other publicly available information (such a peer-reviewed scientific articles), and mandatory reports from the animal drug sponsor (the company that owns the right to market the drug).

If you have used the products on your pet and notice any adverse reactions, it's important to consult your veterinarian and report the reaction to either the drug manufacturer or directly to the FDA.

The flea and tick medicine are in the isoxazoline class, the FDA said Thursday.

FDA-approved drugs that contain the pesticide isoxazoline are sold under the brand names Bravecto, Credelio, Nexgard and Simparica. Fleas and ticks carry a range of diseases, including Lyme disease and plague, which can affect not only the animals but their owners.

If your dog or cat experiences an adverse reaction to the process, it is important to contact your veterinarian to see what is safe to use on your pets. These drugs are not being recalled or banned, but the FDA has felt the need to alert pet owners to the possibility that the drugs can be potentially troublesome for some pets. The FDA has been collecting and monitoring reports of these types of reactions from drugs in this class and urges pet owners who notice anything odd to contact either the FDA directly or any of the manufacturers who produce the drugs, including Merck, Elanco, Merial, and Zoetis.
