[MAH (GDS)]: O - Unclassifiable/unassessable 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. But seizures were 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. Other causes are more likely. Time to onset is long after initial collar application. Fleas were reported long time after collar removal. Hence not related to product. Further reported death is not expected with appropriate collar application. It is not consistent with pharmaco-toxicological product profile. Time to onset is short for later reported seizure and subsequent death after reapplication of collar. However other underlying causes should be considered for this geriatric dog. Product involvement is considered unassessable.
