Question: Can you take ceftriaxone if you are allergic to penicillin?

Cephalothin, cephalexin, cefadroxil, and cefazolin confer an increased risk of allergic reaction among patients with penicillin allergy. Cefprozil, cefuroxime, cefpodoxime, ceftazidime, and ceftriaxone do not increase risk of an allergic reaction.

The risk for penicillin cross-reactivity between most second-generation (cefoxitin) and all third generation cephalosporins (cefixime and ceftriaxone) is negligible (428-431); cefoxitin, cefixime, and ceftriaxone do not have an R group side chain similar to penicillin G.
