Blepharitis: low death-coded share in the FDA AER plate

Signature read: Blepharitis's 2.4% 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: 2 of 82 reports (2.4% of named reports). Nearest volume peer: Injection site haematoma (±0 reports). Lead species Dog (73). Lead co-reported drug Oclacitinib Maleate (8).

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.
