Next-line protocol — Penicillin allergy
Acute otitis media with penicillin allergy: what to do when oral cephalosporins have not resolved symptoms
Clinical scenario
This protocol applies to patients with acute otitis media — acute onset, middle ear effusion, physical evidence of middle ear inflammation, and symptoms including ear pain, irritability, or fever — who have a known penicillin allergy.
Previous treatment — expected response not achieved
An oral cephalosporin was the initial antibiotic approach for this penicillin-allergic patient. The expected outcome — improvement or resolution of ear pain and fever within 48 to 72 hours — was not reached. This protocol defines the next step after that failure.
Treatment approach (partial overview)
When an oral cephalosporin has not resolved acute otitis media in a penicillin-allergic patient, alternative options — including a parenteral agent, a different antibiotic class, or a procedural intervention — may be considered.
Full drug selection, regimen details, and the clinical decision sequence are available in the complete protocol.
