Signs and symptoms of an [[allergic reaction]] include rash, itching, swelling, trouble breathing, or red, blistered, swollen, or peeling skin. Overall, cefalexin allergy occurs in less than 0.1% of patients{{Citation needed|date=August 2023|reason=The claim that adverse side effects only in 0.1% of patients is simply not credible}}. Evidence suggests that it is seen in 1% to 10% of patients with a penicillin allergy.<ref name="AustriaCodex">{{cite book|title=Austria-Codex|editor=Haberfeld, H|publisher=Österreichischer Apothekerverlag|location=Vienna|year=2009|edition=2009/2010|isbn=978-3-85200-196-8|language=de}}</ref>
