What the FDA AER plate says about Nasal congestion

Signature read: 51 death-coded reports is a heavy tail count for Nasal congestion in the CVM extract. Report volume is upper-third scale: 353 named reports in the openFDA extract. 51 of 353 reports were death-coded (14.4% of named reports, not a population mortality rate). Nearest volume peer: Increased weight (±0 reports). Lead species Dog (210). Lead co-reported drug Maropitant Citrate (47).

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