Cephalosporins can be prescribed safely for penicillin-allergic patients

Michael E Pichichero. J Fam Pract. 2006 Feb.

Abstract

The widely quoted cross-allergy risk of 10% between penicillin and cephalosporins is a myth. Cephalothin, cephalexin, cefadroxil, and cefazolin confer an increased risk of allergic reaction among patients with penicillin allergy. Cefprozil, cefuroxime, cefpodoxime, ceftazidime, and ceftriaxone do not increase risk of an allergic reaction.
