Indications And Usage Pre-Pen Is Indicated For The Assessment Of Sensitization To Penicillin (Benzylpenicillin Or Penicillin G) In Patients Suspected To Have Clinical Penicillin Hypersensitivity. A Negative Skin Test To Pre-Pen Is Associated With An Incidence Of Immediate Allergic Reactions Of Less Than 5% After The Administration Of Therapeutic Penicillin, Whereas The Incidence May Be More Than 50% In A History-Positive Patient With A Positive Skin Test To Pre-Pen. These Allergic Reactions Are Predominantly Dermatologic. Whether A Negative Skin Test To Pre-Pen Predicts A Lower Risk Of Anaphylaxis Is Not Established. Similarly, When Deciding The Risk Of Proposed Penicillin Treatment, There Are Not Enough Data At Present To Permit Relative Weighing In Individual Cases Of A History Of Clinical Penicillin Hypersensitivity As Compared To Positive Skin Tests To Pre-Pen And/or Minor Penicillin Determinants.
