Unexpected cefazolin anaphylaxis in a 5-month-old girl.

摘要

As far as we know, our patient may be the first and the youngest case to experience cefazolin anaphylaxis in this age group. In conclusion, although it is very rare, children can experience cefazolin anaphylaxis without a documented cefazolin or penicillin allergy due to cross-reactivity among all (3-lactam antibiotics. Pediatricians must be careful when administering cefazolin to patients through the parenteral route and be familiar with the management of anaphylaxis.
