    The frequency of cephalosporin cross-reactivity in a penicillin-allergic patient is reported to range anywhere from 7% to 18% of patients.

    The package insert for most cephalosporins currently states, "Crosshypersensitivity among the β-lactam antibiotics has been clearly documented and may occur in up to 10% of patients with penicillin allergy."
