Acute Otitis Media When Initial Amoxicillin Treatment Has Not Resolved Symptoms
This protocol applies when acute otitis media — confirmed by acute onset, middle ear effusion, and physical signs of middle ear inflammation, with ear pain, irritability, or fever — persists in a patient without penicillin allergy despite a course of first-line antibiotic therapy.
Clinical Scenario
Acute otitis media is diagnosed with acute symptom onset, middle ear effusion on examination, physical evidence of middle ear inflammation, and symptoms including pain, irritability, or fever. No known penicillin allergy is present, placing the patient within the standard first-line antibiotic pathway — yet symptoms have continued beyond the expected response window.
Prior Treatment & Failure Condition
First-line management with high-dose amoxicillin — the antibiotic of choice in patients without penicillin allergy — did not achieve the expected outcome: improvement or resolution of ear pain and fever within 48 to 72 hours. Persistent symptoms after this window indicate the need for reassessment and escalation to the next treatment step.
Next-Step Approach (Partial Overview)
When amoxicillin has not produced the expected improvement, this protocol covers switching to a second-line antibiotic with broader antimicrobial coverage. The complete regimen — including agent selection, dosing, route, and duration — is available in the full protocol below.

Acute otitis media is diagnosed in patients with acute onset, presence of middle ear effusion, physical evidence of middle ear inflammation, and symptoms such as pain, irritability, or fever.
High-dose amoxicillin (80 to 90 mg per kg per day) is the antibiotic of choice for treating acute otitis media in patients who are not allergic to penicillin.
Children with persistent symptoms despite 48 to 72 hours of antibiotic therapy should be reexamined, and a second-line agent, such as amoxicillin/clavulanate, should be used if appropriate.
