19. Provide supplemental information here

O - Unclassifiable/unassessable Off label use of product as partial pippete of appropriate size used. Serious nervous system disorders such as seizures are not anticipated with topical administration of Advantage II. 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. Unknown whether seizures were confirmed by vet or only observed by owner. Death is inconsistent with pharmaco-toxicological product profile and experience. No signs of allergic/anaphylactic reaction reported. 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. Furthermore some information (e.g. medical history, state of heath and necropsy results) missing, hence a product relation is unassessable.
