AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
PRE-PEN is a diagnostic agent containing benzylpenicilloyl polylysine, used as a skin test reagent to assess penicillin allergy status in patients. It functions as a hapten-carrier complex that binds to IgE antibodies specific to penicillin metabolites, enabling detection of Type I hypersensitivity reactions. This injectable formulation helps clinicians identify true penicillin allergy before prescribing beta-lactam antibiotics.
