Translated & summarized from Maariv by baba
A new study from Hillel Yaffe Medical Center found that nearly all children suspected of penicillin allergy are not actually allergic. Dr. Vered Shichter-Konfino highlighted that misdiagnoses can lead to unnecessary use of alternative antibiotics, increasing resistance. The study recommends re-evaluation for children previously labeled as allergic to penicillin.

- Most children suspected of penicillin allergy are not allergic, a new study from Hillel Yaffe Medical Center found.
- Approximately 99% of children tested showed no allergic reaction to penicillin in a recent study.
- Misdiagnosing penicillin allergy can lead to the use of broader-spectrum antibiotics and increased resistance.
- The study followed children for five years, finding many resumed penicillin use without issues.
- Parents and physicians are urged to re-evaluate previous penicillin allergy diagnoses.
A new study conducted at Hillel Yaffe Medical Center has revealed that the vast majority of children suspected of penicillin allergy are, in fact, not allergic to the drug at all. Dr. Vered Shichter-Konfino, Director of the Immunology and Allergology Unit, stated that a misdiagnosis of penicillin allergy can have significant consequences.
The research found that approximately 99% of children who underwent an oral challenge test did not develop an allergic reaction, indicating they were not allergic to penicillin. The study also followed up on penicillin use for five years after the initial assessment. Among 240 children with full tolerance and available follow-up data, 63.7% resumed using penicillin without reporting adverse reactions, while 36.3% did not have a documented repeat use, either due to lack of clinical need, parental fear, misunderstanding of instructions, or physician hesitation.
Dr. Shichter-Konfino emphasized the importance of ensuring parents understand the implications of allergy test results, so children can receive appropriate treatment when needed. She explained that failing to administer penicillin when appropriate may lead to the use of alternative, sometimes broad-spectrum, antibiotics, increasing the risk of side effects and contributing to antibiotic resistance.
The study's message is that a rash during antibiotic treatment does not necessarily indicate an allergy. The medical center recommends that children previously identified as penicillin-allergic consult an allergy specialist for evaluation rather than avoiding the medication lifelong without medical justification. It is also advised not to renew treatment independently before a proper assessment is completed.
