What is the treatment for otitis media?

Treatment of Acute Otitis Media

High-dose amoxicillin (80-90 mg/kg/day in 2 divided doses) is the first-line antibiotic for most children and adults with acute otitis media, but immediate antibiotics are not always necessary—children ≥2 years with mild-to-moderate symptoms and reliable follow-up can be managed with watchful waiting. 1

Initial Management Decision: Antibiotics vs. Observation

The decision to start immediate antibiotics depends on age, symptom severity, and laterality:

Immediate antibiotics are required for: 1

• All children <6 months of age
• Children 6-23 months with severe AOM or bilateral non-severe AOM
• Adults with severe symptoms
• Any patient when follow-up cannot be ensured

Observation without immediate antibiotics is appropriate for: 1, 2

• Children 6-23 months with non-severe unilateral AOM
• Children ≥24 months with non-severe AOM

When choosing observation, you must establish a mechanism to ensure follow-up within 48-72 hours and provide immediate antibiotic initiation if symptoms worsen or fail to improve. 1

Pain Management: The Non-Negotiable First Step

Pain control must be addressed immediately in every patient, regardless of whether antibiotics are prescribed. 1 This is critical because:

• Antibiotics provide no symptomatic relief in the first 24 hours 1
• Even after 3-7 days of antibiotic therapy, 30% of children younger than 2 years may have persistent pain or fever 1
• Analgesics such as acetaminophen or ibuprofen should be initiated within the first 24 hours and continued as long as needed 1

First-Line Antibiotic Selection

High-dose amoxicillin is the preferred first-line agent due to its effectiveness against common pathogens (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis), safety profile, low cost, acceptable taste, and narrow microbiologic spectrum. 1, 2

Dosing: 1

• Pediatric: 80-90 mg/kg/day in 2 divided doses
• Adult: 1.5-4 g/day

Switch to amoxicillin-clavulanate (90 mg/kg/day of amoxicillin with 6.4 mg/kg/day of clavulanate in 2 divided doses) as first-line when: 1, 2

• Patient received amoxicillin in the previous 30 days
• Concurrent purulent conjunctivitis is present
• Coverage for beta-lactamase-producing organisms is needed (particularly H. influenzae and M. catarrhalis)

The FDA label confirms that amoxicillin-clavulanate 45/6.4 mg/kg/day divided every 12 hours demonstrated 87% clinical efficacy at end of therapy for acute otitis media, with significantly lower diarrhea rates (14%) compared to every 8-hour dosing (34%). 3

Penicillin-Allergic Patients

For patients with penicillin allergy, alternative antibiotics include: 1

• Cefdinir (14 mg/kg/day in 1-2 doses)
• Cefuroxime (30 mg/kg/day in 2 divided doses)
• Cefpodoxime (10 mg/kg/day in 2 divided doses)
• Ceftriaxone (50 mg IM or IV per day for 1-3 days)

Important caveat: Cross-reactivity between penicillins and second/third-generation cephalosporins is lower than historically reported, making these cephalosporins generally safe for patients with non-severe penicillin allergy. 1

Treatment Duration

The duration of antibiotic therapy is age and severity-dependent: 1, 2

• Children <2 years or severe symptoms: 10-day course
• Children 2-5 years with mild-to-moderate AOM: 7-day course (equally effective as 10 days)
• Children ≥6 years with mild-to-moderate AOM: 5-7 day course

Management of Treatment Failure

If symptoms worsen or fail to improve within 48-72 hours of initial treatment: 1, 2

1. Reassess the patient to confirm AOM diagnosis
2. Switch to amoxicillin-clavulanate if initially treated with amoxicillin
3. If already on amoxicillin-clavulanate, consider intramuscular ceftriaxone (50 mg/kg/day for 1-3 days)
4. A 3-day course of ceftriaxone is superior to a 1-day regimen for AOM unresponsive to initial antibiotics 1

For children with multiple treatment failures: Consider tympanocentesis with culture and susceptibility testing to guide antibiotic selection based on actual pathogens and resistance patterns. 1

Research data confirm that beta-lactamase-producing organisms (particularly H. influenzae) are the predominant pathogens in children failing high-dose amoxicillin therapy, supporting the switch to beta-lactamase-stable agents. 4

Special Situation: AOM with PE Tube in Place

Topical fluoroquinolone antibiotics (ofloxacin or ciprofloxacin) are first-line therapy for acute tube otorrhea. 5 The presence of a functioning PE tube converts the infection to an accessible external/middle ear infection that responds well to topical therapy, and oral antibiotics are generally unnecessary. 5

Consider oral antibiotics only when: 5

• Systemic symptoms (high fever, severe illness) or complications like mastoiditis are present
• Topical therapy fails after 48-72 hours
• Concurrent AOM exists in the contralateral ear without a tube

Critical pitfall: Never use aminoglycoside-containing drops when a PE tube is present, as these are ototoxic and have direct access to the middle ear. 5

Post-Treatment Follow-Up and Otitis Media with Effusion

After successful antibiotic treatment, middle ear effusion persists in 60-70% of children at 2 weeks, 40% at 1 month, and 10-25% at 3 months. 1 This is defined as otitis media with effusion (OME) when clinical symptoms have resolved and requires monitoring but not antibiotics. 1, 2

For OME: Watchful waiting for 3 months with age-appropriate hearing testing is recommended, with surgical intervention (tympanostomy tubes) considered for bilateral disease persisting >3 months, hearing loss, or significant effect on the child's well-being. 1

Prevention Strategies

Risk reduction strategies include: 1, 2

• Breastfeeding for at least 6 months
• Avoiding tobacco smoke exposure
• Reducing or eliminating pacifier use after 6 months of age
• Minimizing daycare attendance when possible
• Pneumococcal conjugate vaccination (PCV-13)
• Annual influenza vaccination

Long-term prophylactic antibiotics are discouraged for recurrent AOM. 1 For recurrent cases, tympanostomy tube placement should be considered, with failure rates of 21% for tubes alone and 16% for tubes with adenoidectomy. 1

Critical Pitfalls to Avoid

• Do not use corticosteroids (including prednisone) routinely in the treatment of acute otitis media, as current evidence does not support their effectiveness. 1
• Antibiotics do not eliminate the risk of complications like acute mastoiditis—33-81% of mastoiditis patients had received prior antibiotics. 1
• Do not use topical antibiotics for suppurative otitis media without a functioning PE tube; these are only indicated for otitis externa or tube otorrhea. 1
