In this edition of the "Peer to Peer" audiocast series, Dr. Vincent DeLeo speaks with Dr. Susan T. Nedorost about using patch testing as a diagnostic tool for suspected drug eruptions. Dr. Nedorost discusses challenges dermatologists may encounter when using patch testing in cohorts that present with potential drug eruptions and describes settings in which this technique may be most useful for patients. She also emphasizes that drug reactions sometimes may be caused by the product's excipients, not the drug itself.
