What the FDA AER plate says about Alkaline urine

Signature read: 465 reports place Alkaline urine in the upper third of FDA AER volume (#669 of 2,481). Report volume is upper-third scale: 465 named reports in the openFDA extract. 50 of 465 reports were death-coded (10.8% of named reports, not a population mortality rate). Nearest volume peer: Ear pain (±0 reports). Lead species Dog (433). Lead co-reported drug Milbemycin Oxime + Spinosad (75).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Milbemycin Oxime + Spinosad 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.
