An Introduction Video to Penicillin Delabeling
Do you Know?
• Penicillin is the most common drug allergy in hospitalized patients
• 10 - 20% of the US population have a documented Penicillin allergy
• More than 95% of Penicillin allergic patients are not Penicillin allergic
• 80% of people lose their allergy after 10 years.
• Serious allergies such as anaphylaxis are rare - estimated to be< 0.04%
• The most common allergic reaction is a cutaneous eruption/rash

When there is a penicillin allergy label in the electronic health record (EHR) there are increased risks for:
- Treatment failures and suboptimal treatments
- Adverse drug events - vancomycin nephrotoxicity
- Clostridioides difficile infections
- Development of antibiotic resistance
- Surgical site infections


Positive clinical effects from Penicillin allergy delabeling
- Enable beta-lactam antibiotic treatment options
- Lower adverse drug events (ADEs)
- Reduce exposure to antibiotics causing Clostridioides difficile infections
- Enable use of appropriate preoperative prophylactic antibiotic
There are significant financial benefits from delabeling patients
- Shortened length of stay (LOS)
- Decreased readmission rates
- Reduction in healthcare expenses
