Drugs within a group have similar R1-side chains and display cross-allergic reactions (whereas drugs in different groups are not cross-allergic): Penicillin, aminopenicillins & selected G1-G2 cephalosporins Cefazolin Nafcillin Piperacillin-tazobactam Cefepime & most G3 cephalosporins Ceftazidime & aztreonam Ceftaroline Carbapenems types of drug reaction types of drug reaction Drug reactions vary greatly
