Medication for Otitis Media
For acute otitis media, amoxicillin at high doses (80-90 mg/kg/day in children; 1.5-4 g/day in adults) is the first-line antibiotic, with amoxicillin-clavulanate as the preferred second-line agent. 1, 2, 3
Pediatric Treatment Algorithm
Initial Antibiotic Selection by Age and Severity
Children <6 months:
- Immediate antibiotics required regardless of severity 3, 4
- High-dose amoxicillin 80-90 mg/kg/day divided into 2-3 doses for 10 days 3, 4
Children 6-23 months:
- Severe AOM (moderate-to-severe otalgia OR fever ≥39°C) or bilateral AOM: immediate antibiotics 3
- Non-severe unilateral AOM: observation acceptable with reliable 48-72 hour follow-up 3
- If antibiotics chosen: amoxicillin 80-90 mg/kg/day for 10 days 3
Children ≥2 years:
- Severe symptoms: immediate antibiotics, 7-10 day course 3
- Mild-moderate symptoms: observation acceptable with follow-up 3
- If antibiotics chosen: amoxicillin 80-90 mg/kg/day for 7 days (ages 2-5) or 5-7 days (ages ≥6) 3
When to Use Amoxicillin-Clavulanate Instead
Use amoxicillin-clavulanate 90 mg/kg/day (based on amoxicillin component) as first-line if: 3
- Amoxicillin received within previous 30 days
- Concurrent purulent conjunctivitis present
- Recurrent AOM unresponsive to amoxicillin
- Attends daycare (higher risk of beta-lactamase producers) 4
Treatment Failure Management
If symptoms worsen or fail to improve within 48-72 hours: 3, 4
- Reassess to confirm AOM diagnosis
- If initially on amoxicillin: switch to amoxicillin-clavulanate 90 mg/kg/day 3, 4
- If initially on amoxicillin-clavulanate: switch to ceftriaxone 50 mg/kg IM/IV daily for 3 days (maximum 1-2 grams) 3, 4
- Three-day ceftriaxone course superior to one-day regimen 3
Penicillin Allergy Alternatives
For non-type I hypersensitivity (non-severe allergy): 3
- Cefdinir 14 mg/kg/day in 1-2 divided doses
- Cefuroxime axetil 30 mg/kg/day in 2 divided doses
- Cefpodoxime 10 mg/kg/day in 2 divided doses
- Cross-reactivity with second/third-generation cephalosporins is negligible 3
For true type I IgE-mediated allergy: 3
- Macrolides (azithromycin) are safest but have lower efficacy against resistant organisms
- Azithromycin dosing: 30 mg/kg single dose OR 10 mg/kg day 1, then 5 mg/kg days 2-5 5
Adult Treatment Algorithm
First-Line Therapy
Amoxicillin-clavulanate is preferred over plain amoxicillin in adults due to higher rates of beta-lactamase-producing organisms (17-34% of H. influenzae, 100% of M. catarrhalis) 2
- Standard dose: 3 g/day amoxicillin component 2
- High-dose for risk factors: 2000 mg/125 mg twice daily 2
Risk factors requiring high-dose therapy: 2
- Antibiotic use within past month
- Age >65 years
- Moderate-to-severe symptoms
- Comorbid conditions or immunocompromised status
- Geographic regions with high penicillin-nonsusceptible S. pneumoniae rates
Treatment Duration in Adults
5-7 days is appropriate for uncomplicated cases 2
- Shorter courses have fewer side effects than traditional 10-day regimens 2
- Adults have different immune responses and lower treatment failure risk than young children 2
Treatment Failure in Adults
Reassess at 48-72 hours if symptoms persist or worsen: 2
- Consider respiratory fluoroquinolones (levofloxacin, moxifloxacin) or ceftriaxone 2
- Do not simply extend duration of failing antibiotic 2
Penicillin Allergy in Adults
For non-type I allergy: 2
For severe allergy: 2
- Respiratory fluoroquinolones (though avoid as first-line due to resistance concerns) 2
Pain Management (All Ages)
Pain control is mandatory and must be addressed immediately in every patient, regardless of antibiotic decision: 2, 3
- Acetaminophen or ibuprofen in age-appropriate doses 2, 3
- Continue throughout acute phase, especially first 24 hours 3
- Pain relief often occurs before antibiotics provide benefit 3
Critical Pitfalls to Avoid
- Isolated tympanic membrane redness with normal landmarks does NOT indicate AOM 1, 2
- Do not confuse otitis media with effusion (OME) for acute AOM—OME does not require antibiotics 2, 3
- Proper pneumatic otoscopy with visualization of bulging, limited mobility, or distinct erythema is essential 2
- NSAIDs at anti-inflammatory doses and corticosteroids have NOT demonstrated efficacy for AOM 2, 3
- Do NOT use macrolides or trimethoprim-sulfamethoxazole as first-line (>40% and 50% resistance rates respectively against S. pneumoniae) 2
- Do NOT use trimethoprim-sulfamethoxazole or erythromycin-sulfisoxazole for treatment failures due to substantial resistance 3, 4
- Long-term prophylactic antibiotics are discouraged for recurrent AOM 3
Post-Treatment Follow-Up
Middle ear effusion commonly persists after successful treatment: 3
- 60-70% at 2 weeks, 40% at 1 month, 10-25% at 3 months 3
- This post-AOM effusion (OME) requires monitoring but NOT antibiotics unless persisting >3 months with hearing loss 3
Prevention Strategies
Modifiable risk factors: 3
- Encourage breastfeeding ≥6 months
- Reduce/eliminate pacifier use after 6 months
- Avoid supine bottle feeding
- Eliminate tobacco smoke exposure
- Minimize daycare attendance when possible
Immunizations: 3
