Acute Otitis Media Persisting After Initial Antibiotic Therapy
This protocol applies to patients with confirmed acute otitis media — acute onset, middle ear effusion, physical evidence of middle ear inflammation, and symptoms including ear pain, irritability, or fever — who have no known penicillin allergy and whose condition has not responded to the initial antibiotic course.
When the First-Line Treatment Did Not Work
For patients without penicillin allergy, the initial antibiotic approach — high-dose amoxicillin/clavulanate orally or ceftriaxone parenterally — is expected to produce improvement or resolution of ear pain and fever within 48 to 72 hours. When symptoms persist beyond this window, escalation to a next-line protocol is indicated.
What Comes Next
When acute otitis media fails to respond within 48–72 hours, a next-line approach involving alternative antibiotic combinations — and, in selected cases, parenteral therapy, a procedural intervention, or specialist referral — is indicated. The complete evidence-based regimen is available in the full protocol.

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.
High-dose amoxicillin should be the initial treatment in the absence of a known allergy.
If symptoms persist despite appropriate antibiotic therapy, consider intramuscular ceftriaxone (Rocephin), clindamycin, or tympanocentesis.
Clindamycin (30-40 mg/kg per day in 3 divided doses) plus third-generation cephalosporin
