To the Editor We read with great interest the article by Sousa-Pinto and colleagues1 on cefazolin and penicillin allergies. This is an important topic on administration of preferred antibiotics for prophylaxis of surgical site infection (SSI). The authors reported a meta-analytical frequency of 0.7% for patients with penicillin allergy history and allergy to cefazolin (dual allergy).1 They suggested that most patients with a history of penicillin allergy may safely receive cefazolin, with the exception of patients with confirmed penicillin allergy.1 However, given the low frequency of penicillin-cefazolin dual allergy, determined cefazolin should be administered regardless of penicillin allergy history.1
