From: Penicillin and cephalosporin cross-reactivity: role of side chain and synthetic cefadroxil epitopes
a The diagnostic algorithm includes skin tests (STs) to PPL/BP-OL, MDM/DM and amoxicillin (AX) and if negative drug provocation tests (DPT) to penicillin V (PV) and AX. Patients were classified into two groups, allergic to the whole group of penicillins or selective reactors to AX. b Cross reactivity to cefadroxil (CX) was analysed by STs and DPT and AX-allergic patients classified into two groups: Group A with good tolerance and Group B with cross-reactivity. In all cases cross-reactivity with cefuroxime (CO) was also analysed by ST and DPT
