Cross-reactivity among penicillins and cephalosporins is attributed to similarity in side chains. 3. Cephalosporin cross-reactivity with penicillins is much lower than reported in early studies partly due to contamination of study drugs with penicillin. 4. Cross-reactivity between cephalosporins is about 2% and with carbapenems is <1%. crosman tr77 nps australia Webthe cephalosporins are close relatives of penicillins. and share a structure called the beta-lactam ring, the risk of a cross-reactivity reaction between penicillins and cephalosporins remains <5%. Therefore, even with a true allergy to penicillin, there is an excellent chance you could tolerate cephalosporins.
