Up to 10% of children are reported to be allergic to penicillin, but many allergy labels are unverified and may require formal testing.

Patients with hematological disorders may experience frequent and severe infections; those who have been incorrectly labeled penicillin allergic may benefit from allergy de-labeling (ADL) efforts to facilitate access to beta-lactam antibiotics.
