O - Unclassifiable/unassessable Serious nervous system disorders such as seizures are not anticipated with topical administration of the product. From a toxicological point of view, neither imidacloprid nor pyriproxyfen does have the potential to provoke seizures in vertebrates. In case of oral ingestion of a considerable amount of product or after administration of an overdose shortly after product application, neurological symptoms such as tremor, ataxia, depression, miosis or mydriasis may occur. But seizures are not expected. Various etiologies exist for seizure events or paroxysmal signs, e.g. heart disorder, development disorder, metabolic disorder, infection, intoxication, idiopathic epilepsy, trauma, neoplasms. Time to onset is unknown. Weakness and anorexia are unspecific, however in this case signs may be associated with reported seizure. Further reported death is inconsistent with pharmaco-toxicological product profile and experience. Product has wide margin of safety. Oral LD50 in rat is 642 mg/kg BW. 24-fold overdosage tolerated by cats without showing any side effect. Considering limited information such as animal details, health status, medical history, time to onset and necropsy details, a product relation is unassessable.
