Is it possible for you to take cephalexin if you r allergic to penicillins?

Dr. Doanh Nguyen, md, faaaai answered

Specializes in Allergy and Immunology

Yes: Cross reactivity between the two classes are low so Cephalexin is not contraindicated in penicillin allergy patients. You should have your prescribing physician to follow you for any signs of reactions and get proper treatment.
