What the FDA AER plate says about Sleep disturbance NOS
Signature read: 551 reports place Sleep disturbance NOS in the upper third of FDA AER volume (#605 of 2,481). Report volume is upper-third scale: 551 named reports in the openFDA extract. 48 of 551 reports were death-coded (8.7% of named reports, not a population mortality rate). Nearest volume peer: Gastric ulcer (±0 reports). Lead species Dog (487). Lead co-reported drug Trilostane (70).
Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Trilostane 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.
