Your Answer: True

  • Penicillin allergy is the most frequently documented drug allergy in medical records, with a prevalence of approximately 10% of all patients.
  • However, in up to 90% of patients with a reported allergy, penicillins are tolerated on allergy testing.
  • Amongst patients labeled as having a penicillin allergy, alternative (and typically broader-spectrum) antibiotic classes are often prescribed, with potentially poorer efficacy and safety profiles. This can lead to increased antimicrobial resistance, risk of C. difficile infection, treatment failure, healthcare costs and prolonged hospitalizations.
