Off label use of the product as product was administered in ear. Initially reported unspecified neurological signs are not anticipated with appropriate topical product administration. Even with oral product exposure which was not reported only transient gastrointestinal signs but no neurological signs would be expected. Worsening of pre-existing tumor and diagnosed tumor in another ear is not expected after product administration as not in line with pharmaco toxicological product profile. Later observed neurological signs, anorexia and discomfort likely associated with reported tumor in ears. Reported application site disorders are not expected after appropriate product administration, moreover in this case reported application site disorders associated with worsening of ear tumor. 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. Animal involved in this case was geriatric and had concomitant condition of tumor which may have further contributed to the death of the animal. Time to onset is unknown for initial reported signs but it is too long for later observed signs. In case of suspected product involvement adverse event would have been reported in close proximity not long time after (almost 7 months later). Even though some information is not available (animal health status and necropsy report), sufficient information exists to rule out product relation completely. Overall, a product relation is consider as unlikely.
