Title |
Minimal Risk Of Severe Type 1 Hypersensitivity Reaction To Third Generation Cephalosporin In Patients Who Experience Type 1 Hypersensitivity Reaction And Allergy To Penicillin |
Clinical Question |
Do patients who experience a severe type 1 hypersensitivity reaction to penicillin and demonstrate an allergy to cephalosporin experience a severe type 1 hypersensitivity reaction to the cephalosporin? |
Clinical Bottom Line |
It appears that patients who have a severe type 1 hypersensitivity reaction to penicillin do not have an increased risk of anaphylaxis to cephalosporins. This evidence may be skewed however by adherence to the recommendation not to give cephalosporins to individuals with a history of penicillin anaphylaxis. (See Comments on the CAT below) |

by Julie Berkhoff (CO) on 08/04/2011 A more recent systematic review published in 2008 by the Journal of the American Pharmacists Association (PubMed: 18653431) confirmed a very low incidence of cross-reactivity based on oral re-challenge and skin testing to verify true allergic reaction vs non-allergic adverse reaction. This study included both animal and human studies. | |
