Reports of neurological problems in dogs and cats prompted the FDA to issue an alert Thursday to pet owners and vets about isoxazoline drugs used to treat flea and/or tick infestations.
“...data received by the agency as part of its routine post-marketing activities indicates that some animals receiving Bravecto, NexGard or Simparica have experienced adverse events such as muscle tremors, ataxia, and seizures,” the alert read. “Another product in this class, Credelio, recently received FDA approval. “
The FDA says it’s working with drug makers to get labels on these drugs to warn of these potential issues so each vet and pet owner can make an informed decisions for the pet family member(s).
“The FDA carefully reviewed studies and other data on Bravecto, Credelio, Nexgard and Simparica prior to approval, and these products continue to be safe and effective for the majority of animals” the alert said.
