#66 – The Swinging PEN-dulum: Evolving Approaches to Cephalosporin Use in Penicillin Allergic Patients

Dr. Kimberly Blumenthal (@KimberlyBlumen1), Dr. Meghan Jeffres (@PharmerMeg), and Dr. Eric Macy (@EricMacyMD) join Dr. Julie Ann Justo (@julie_justo) to summarize the history of cephalosporin avoidance in penicillin allergies, evidence-based pros and cons of giving cephalosporins in penicillin allergy, how to leverage technology to improve treatment of patients with penicillin allergies, and much more!
