Recently the FDA posted an alert that the flea and tick medications in the isoxazoline class are now carrying a possible seizure risk in dogs and ataxia in cats. We have used Nexgard and Bravecto in not only our patients but our own cats and dogs for many years. We do not recommend these products in pets with neurological disorders.
