In addition, later generation (e.g. third and fourth) cephalosporins exhibit a near 0% cross-reactivity rate. The cephalosporin referred to in the question, cefdinir, is classified as a third generation cephalosporin. It would be extremely uncommon for a penicillin allergic patient to experience a cross-reactivity reaction on this medication.Cephalosporin administration with a penicillin allergy history.
