Increased skin sensitivity: low death-coded share in the FDA AER plate

Signature read: Increased skin sensitivity's 4.5% death-coded share is among the lowest in the openFDA reaction corpus. Report volume sits in the middle third of the reaction corpus. Death-coded share is lower-third: 13 of 291 reports (4.5% of named reports). Nearest volume peer: Lack of efficacy (protozoa) (±0 reports). Lead species Dog (188). Lead co-reported drug Milbemycin Oxime + Spinosad (25).

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.
