STATEN ISLAND, N.Y. -- The U.S. Food & Drug Administration is warning pet owners and veterinarians that common pet and tick medications can cause serious neurological problems in animals.
The alert includes drugs that are in the isoxazoline class, such as Bravecto, Credelio, Nexgard and Simparica. Most of the medications are sold as flavored chews.
"Isoxazoline products have been associated with neurologic adverse reactions, including muscle tremors, ataxia, and seizures in some dogs and cats," the FDA said in a news release. "Although most dogs and cats haven't had neurologic adverse reactions, seizures may occur in animals without a prior history."
While these products can and have been safely used in majority of dogs and cats, the FDA encourages pet owners to consult with their veterinarian to review medical histories and determine whether a product in the isoxazoline class is appropriate for their pet.
Many products are available for prevention and control of flea and tick infestations, the FDA said.
If your pet experiences any adverse effect while using an isoxazoline product, first consult with your veterinarian. The FDA also advises pet owners to report the incident to the drugs' manufacturers.
