What the FDA AER plate says about Hypersalivation

Signature read: 10,540 reports place Hypersalivation in the upper third of FDA AER volume (#43 of 2,481). Report volume is upper-third scale: 10,540 named reports in the openFDA extract. 886 of 10,540 reports were death-coded (8.4% of named reports, not a population mortality rate). Nearest volume peer: Itching (±200 reports). Lead species Dog (5,415). Lead co-reported drug Imidacloprid + Moxidectin (1,097).

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.
