Correct answer: DSubmit a Yellow Card report and advise urgent clinical review

Jaundice after flucloxacillin suggests potentially serious cholestatic hepatitis and requires urgent clinical assessment. Suspected serious adverse drug reactions should be reported through the Yellow Card scheme, even when causality is not proven. Rechallenge could cause further harm.
