Blanket 'cephalosporin allergy' is a myth, immunologists say

Are patients missing out on safe treatment options?

Patients who report an allergy to a specific cephalosporin are unlikely to be allergic to others in the same class of antibiotics, immunologists say.


They warn that patients are being wrongly labelled with “cephalosporin allergy”, which might lead to unnecessarily avoiding safe treatment options and unwarranted use of other broad-spectrum antibiotics.

Writing in Australian Prescriber, the specialists say an allergy to one cephalosporin should not rule out the use of others, and a penicillin allergy should not rule out the use of cephalosporins.
