Penicillin Allergy


10% of the people in United States report that they are allergic to penicillin/amoxicillin. However, studies have shown that 98% of patients who were labeled as penicillin allergic can actually take penicillin after an appropriate allergy evaluation, and has seen an oral challenge. A person who is labeled as penicillin allergic may be exposed to broader–spectrum antibiotics that may be more toxic, less effective, and more costly.


Symptoms of Penicillin allergy include:

  • Hives
  • Swelling
  • Wheezing


The first step will would be skin testing per standard protocol. If the skin tests are negative, then you (or your child) would return for a short in–office oral challenge, followed by a short outpatient course. If you (or your child) remained asymptomatic, then you can be considered not allergic to penicillin/amoxicillin, and related medications.
