Mort
N - Unlikely The product is not anticipated to cause serious neurological disorders such as seizures after appropriate topical product administration as the controlled release mechanism assures release of only low doses of active ingredient at a time. Reported death is not expected either following appropriate topical product application as inconsistent with product's pharmacological profile. Oral exposure to the collar is not expected to cause serious signs. But seizure was reported in connection with product use in dogs. However, it is known that overdose of 5 collars around the neck of adult dogs for an 8 months period and in 7 week old puppies for a 6 months period did not cause serious signs. This is supported by the extremely low systemic exposure with imidacloprid and flumethrin, particularly during the first week after application and also thereafter. Even with oral product exposure, seizures are not seen. Merely gastrointestinal signs may occur. Any action or treatment may trigger seizures in an animal with a respective disposition. Various etiologies exist for seizure events or paroxysmal signs, e.g. heart disorder, development disorder, metabolic disorder, infection, intoxication, idiopathic epilepsy, trauma, neoplasms. In this case, concomitant condition of hypothyroidism must also be considered in this geriatric dog. Time to onset is long. Considering the known product profile sufficient information exists to conclude that the product did not cause the event and product involvement was ruled out. Overall, a product involvement is considered unlikely.
