Reverse sneezing: low death-coded share in the FDA AER plate

Signature read: Reverse sneezing's 5.2% death-coded share is among the lowest in the openFDA reaction corpus. Report volume sits in the middle third of the reaction corpus. Death-coded share is lower-third: 16 of 309 reports (5.2% of named reports). Nearest volume peer: Cloudy eye (for Miosis, Mydriasis, Anisocoria, Nystagmus - see 'Neurological') (±1 reports). Lead species Dog (303). Lead co-reported drug Oclacitinib Maleate (38).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Oclacitinib Maleate appears in filings alongside this reaction; that is association, not causation. Browse the full reactions index or the about page for how PlainBreed frames FDA CVM extracts.
