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

Signature read: Irritability's 7.5% death-coded share is among the lowest in the openFDA reaction corpus. Report volume is upper-third scale: 360 named reports in the openFDA extract. Death-coded share is lower-third: 27 of 360 reports (7.5% of named reports). Nearest volume peer: Application site blister (±0 reports). Lead species Dog (203). Lead co-reported drug Buprenorphine (23).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Buprenorphine 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.
