Flucloxacillin Hypersensitivity: Patient Outcomes in a Multicenter Retrospective Study

ConclusionsImmediate hypersensitivity reactions to flucloxacillin are more common than delayed. Cross-sensitization to other penicillins appears higher in delayed reactions than in immediate. The negative predictive value of intradermal testing is higher in the immediate group than in the nonimmediate group. Drug provocation testing remains the diagnostic criterion standard.
