Cross hypersensitivity between penicillin cephalexin

Penicillin and other βlactam antibiotics act by inhibiting penicillinbinding proteins, which normally catalyze crosslinking of bacterial cell  as a consequence, ddtranspeptidase cannot catalyze formati. The rate of ige mediated crossreactivity between penicillin and cephalosporins is less than 10 for the first and second generations and less than 5 for the third and fourth generations. According to th. There is i think 10 cross sensitivity between penicillin and cephalosporin allergy, so most of us would use cefalexin only if there are no alternatives in penicillinallergic patients.
