title: Potential Cross-Reactivity Between Penicillin Derivatives and Cephalosporins.
abstract: Allergic reactions to both penicillins and cephalosporins are relatively common. Patients who have had a previous allergic reaction to a penicillin derivative may also be prone to a further reaction if treated with cephalosporins. This case illustrates several important points about potential cross-reactivity between penicillin derivatives and cephalosporins, as well as the benefits of an extended-hours pharmacy service in a longterm care facility.
