What the FDA AER plate says about Hyperhidrosis
Signature read: 13 death-coded reports is the most distinctive absolute-outcome stamp on Hyperhidrosis. Report volume sits in the middle third of the reaction corpus. 13 of 104 reports were death-coded (12.5% of named reports, not a population mortality rate). Nearest volume peer: Application site hot spot (±0 reports). Lead species Horse (91). Lead co-reported drug Ceftiofur Crystalline Free Acid (10).
Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Ceftiofur Crystalline Free Acid 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.
