The Food and Drug Administration (FDA) has issued a warning to pet owners and veterinarians about some flea and tick prevention medication.
The FDA says the pills and chews are sold under the brand names Nexgard, Simparica, Bravecto and Credelio and all include the pesticide Isoxazoline.
The products have all received FDA approval, but the organization says some of the adverse reactions associated with Isoxazoline products include muscle tremors, ataxia and seizures.
While the products already mention the risk of the neurological side effects, the FDA said it was requiring clearer labels.
“If your pet experiences a bad reaction from a spot-on product, immediately bathe the pet with mild soap, rinse with large amounts of water, and call your veterinarian,” the FDA advises.
