Intrapartum antibiotic exposure for group B Streptococcus treatment did not increase penicillin allergy in children

To the authors' knowledge, this is the first study to evaluate intrapartum exposure to penicillin for GBS treatment and subsequent development of penicillin allergy in the child. In contrast to other atopic diseases, intrapartum antibiotic exposure does not alter the risk of penicillin allergy. Parents and obstetricians should be reassured when using penicillin for prevention of neonatal GBS.
