19. Provide supplemental information here

O - Unclassifiable/unassessable Reported signs of behavioral change may occur initially after collar application. But time to onset seems too long. further reported swollen tongue, foaming at the mouth, and difficulty breathing are not expected after product application and rather associated with seizure-like episode that the dog experienced. However, 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/convulsions were reported in connection with product use in dogs and were requested by authorities to be content of the EU SPC. 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. 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. Subsequently reported death is not expected following appropriate topical product application as inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause serious signs either. An overdose of 5 collars around the neck was investigated in adult cats and dogs for an 8 months period and in 10 week old kittens and 7 week old puppies for a 6 months period without causing serious signs. No signs of anaphylaxis reported which would have occurred in close proximity to the collar application. Considering the product profile, product involvement is deemed unlikely, however due to limited information, case is considered unassessable.
