Background. - Penicillin hypersensitivity is a common cause of suspected and proven drug allergy and drug-induced anaphylaxis in medical records and causes social and economic burdens. Objective. - Since the rate of clarithromycin hypersensitivity is low in the general population, we aimed to investigate whether clarithromycin can be prescribed to patients with penicillin allergy without a provocation test.Methods. - The medical records of 186 patients referred to our clinic between 2015 and 2021 with a history of penicillin allergy were evaluated retrospectively. Patients having a history of at least two immediate-type hypersensitivity reactions with penicillin antibiotics or having a history of immediate-type hypersensitivity with penicillin and diagnosed by positive penicillin V/G specific IgE and/or penicillin skin tests were included in the study. Penicillin skin tests were performed according to the manu-facturer's instructions. Concentrations of serum specific IgE against phenoxymethylpenicillin (pen V) and benzylpenicillin (pen G) were determined using The Phadia CAP System FEIA method. An oral drug provocation test with clarithromycin was performed in all patients. Results. - The data of 64 patients diagnosed with penicillin allergy and who underwent clarithromycin oral provocation test were analyzed. Oral provocation test with clarithromycin was positive in only two of these patients (3%). These two patients had a history of multidrug hypersensitivity, and one of them also had food and venom allergies.Conclusion. - We suggest that clarithromycin can be given without an oral provocation test when an alter-native antibiotic is required in patients with penicillin allergy and without multidrug hypersensitivity.& COPY; 2023 Elsevier Masson SAS.
