What the FDA AER plate says about Halitosis
Signature read: 69 death-coded reports is a heavy tail count for Halitosis in the CVM extract. Report volume is upper-third scale: 458 named reports in the openFDA extract. 69 of 458 reports were death-coded (15.1% of named reports, not a population mortality rate). Nearest volume peer: Swollen vulva (±2 reports). Lead species Dog (413). Lead co-reported drug Imidacloprid + Moxidectin (116).
Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Imidacloprid + Moxidectin 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.
