The commonly quoted figure of 10% of patients with allergic hypersensitivity to penicillins and/or carbapenems also having cross-reactivity with cephalosporins originated from a 1975 study looking at the original cephalosporins, [9] and subsequent "safety first" policy meant this was widely quoted and assumed to apply to all members of the ...
The simplest β-lactam possible is 2-azetidinone. β-lactams are significant structural units of medicines as manifested in many β-lactam antibiotics. [2] Up to 1970, most β-lactam research was concerned with the penicillin and cephalosporin groups, but since then, a wide variety of structures have been described. [3] [4]
Nevertheless, the risk of cross-reactivity is sufficient to warrant the contraindication of all β-lactam antibiotics in patients with a history of severe allergic reactions (urticaria, anaphylaxis, interstitial nephritis) to any β-lactam antibiotic. Rarely, allergic reactions have been triggered by exposure from kissing and sexual contact ...
Additionally, those with penicillin allergies can usually tolerate cephalosporins (another group of β-lactam) because the immunoglobulin E (IgE) cross-reactivity is only 3%. [5] Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens. [6]

Pathway of penicillin and cephalosporin biosynthesis, illustrating the role of isopenicillin N synthase in the formation of beta-lactam antibiotics Following the IPNS pathway, further enzymes are responsible for the epimerization of isopenicillin N to penicillin N, the derivitazation to other penicillins, and the ring expansion that eventually ...
Penicillin-sensitive patients may also be allergic to the cephalosporins, depending on the side chain and it's relation to the penicillin allergy. Most patients with penicillin allergy can tolerate the majority of cephalosporins without allergic reactions. The previous percentage of 10% cross reactivity rates are a gross overestimation. [7]
Monobactam antibiotics exhibit no IgE cross-reactivity reactions with penicillin but have shown some cross reactivity with cephalosporins, most notably ceftazidime, which contains an identical side chain as aztreonam. [8] Monobactams can trigger seizures in patients with history of seizures, although the risk is lower than with penicillins.
