O - Unclassifiable/unassessable SLEE/fleas. Reported pruritus is not expected with appropriate topical product use. If any, skin reaction would be located at the application site of the collar. Skin disorder in this case rather associated with current flea infestation. However, presence of fleas is not a sign of inefficacy. Product is not a repellent. Fleas have to be on the animal to come into contact with the product to be killed. Fleas were reported after a flea-free time. Sudden appearance of fleas after flea-free time suggests re-infestation with fleas from environment (e.g. other untreated pets, wildlife). This may lead to new establishment of a flea population in pet¿¿¿¿¿¿s environment requiring several weeks of treatment to disappear. Duration of flea infestation is unknown. Moreover, potential contributing factors such as high environmental infestation pressure not clarified. Further, fatal outcome of death is not expected following appropriate topical product application as inconsistent with product¿¿¿¿¿¿s 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. This is supported by the extremely low systemic exposure with imidacloprid and flumethrin, particularly during the first week after application and also thereafter. Previous exposure was well tolerated without any adverse event. However, health details are unknown for the geriatric dog. Time to onset is long. Considering limited information (no necropsy details) provided in the case, a product relation for this case is unassessable.
