II. Pitfalls

  1. Antihistamines and Decongestants are not useful
  2. Antibiotic dosages are often too low

III. Risk factors: Treatment Failure

  1. Otitis Media within the last month
  2. Antibiotic within the last month
  3. Day Care attendance
  4. Bilateral Otitis Media
  5. Age less than 2 years old
  6. Age at first Otitis Media less than 6 months old
  7. Over 3 episodes Acute Otitis Media in last 6 months

IV. Protocol: Observation Protocol

  1. See Observation Protocol for Acute Otitis Media Management
  2. Strongly consider observation <48 hours of symptoms
    1. Age over 2 years OR
    2. Age 6-24 months if no severe symptoms
  3. Antibiotics have few benefits beyond Placebo for ages 2-12 years old with middle ear infection
    1. Otitis Media Diagnosis is highly inaccurate
      1. Asher (2005) Acta Pediatr 94(4): 423-8 [PubMed]
    2. No significant reduction in pain at 24 hours and 2 weeks compared with Placebo
      1. Antibiotics are also associated with adverse effects (Diarrhea, Vomiting, rash)
      2. Venekamp (2015) Cochrane Database Syst Rev (6):CD000219 [PubMed]
    3. Initial antibiotics (versus observation, expectant management) does not reduce Otitis Media complication rates
      1. No difference in Tympanometry at 4 weeks
      2. Marginal difference in Tympanic Membrane Perforation (NNT 33 with antibiotics)
      3. No difference in Otitis Media recurrence
      4. No proven reduction in Mastoiditis
      5. Grossman (2016) Pediatr Infect Dis 25(2): 162-5 [PubMed]

V. Protocol: No Penicillin or Cephalosporin allergy

  1. Antibiotic duration
    1. Age under 2 years: 10 day course
    2. Age 2 to 5 years: 7 day course
    3. Age >5 years: 5 day course (if severe symptoms, use 7 day course)
  2. First Line
    1. Amoxicillin 80-90 mg/kg/day PO divided twice daily for 10 days
    2. If Penicillin Allergy
      1. Use Cephalosporins from second-line list below
        1. Move to third-line therapy if persistent symptoms and signs after 48-72 hours of antibiotics
      2. If unable to use Cephalosporins (due to allergy)
        1. Use alternative agents as shown below
    3. Indications for moving to second-line treatment
      1. Persistent symptoms with bulging, erythematous TM after 48-72 hours on first-line treatment
      2. Amoxicillin in last 30 days
      3. Concurrent Otitis Media with Conjunctivitis
  3. Second Line (10 day course)
    1. Amoxicillin with clavulanate (Augmentin) 90 mg/kg/day divided twice daily for 10 days
    2. Cefuroxime (Zinacef, Ceftin) 30 mg/kg/day divided twice daily for 10 days
    3. Cefprozil (Cefzil) 30 mg/kg/day divided twice daily for 10 days
    4. Cefdinir (Omnicef) 14 mg/kg/day divided one to two times daily fo 10 days
    5. Cefpodoxime (Vantin) 10 mg/kg divided twice daily for 10 days
  4. Third Line
    1. Strongly consider Tympanocentesis for Bacterial culture
    2. Ceftriaxone (Rocephin) 50 mg/kg IM daily for 3 days
    3. Clindamycin 30-40 mg/kg/day divided four times daily for 10 days

VI. Protocol: Agents if Penicillin and Cephalosporin Allergy

  1. Consider Tympanocentesis
  2. Clindamycin (Cleocin) 30-40 mg/kg/day (max 1800 mg) divided four times daily for 10 days
  3. Macrolide antibiotics (High Bacterial resistance rate)
    1. Erythromycin
    2. Clarithromycin (Biaxin) 15 mg/kg/day divided twice daily for 10 days
    3. Azithromycin (Zithromax)
      1. One dose of Azithromycin XR (Zmax) at 30 mg/kg (up to 1500 mg) or
      2. Three days of Azithromycin at 20 mg/kg/day once daily (up to 500 mg/day) or
        1. This high dose approached Augmentin efficacy in one study
        2. Arrieta (2003) Antimicrob Agents Chemother 47:3179 [PubMed]
      3. Azithromycin 10 mg/kg (max: 500 mg) day 1, then 5 mg/kg/day (max 250 mg) for 5 days
  4. Fluoroquinolones (avoid under age 16 years)
    1. Levofloxacin (Levaquin)
    2. Moxifloxacin (Avelox)

VII. Protocol: Topical agents if patent Tympanostomy Tubes

  1. Ciprofloxacin with Hydrocortisone (Cipro HC Otic) 3 drops twice daily for 7-10 days
  2. Ofloxacin (Floxin Otic) 5 drops (10 drops if over age 12) twice daily for 7-10 days

VIII. Follow-up: Persistent Middle Ear Effusion (Otitis Media with Effusion)

  1. Natural course
    1. At 2 weeks: 70% have persistent effusion
    2. At 4 weeks: 40%
    3. At 2 months: 20%
    4. At 3 months: 10%
  2. Persistent effusion at 3 months
    1. See Otitis Media with Effusion
    2. Consider otolaryngology Consultation (including consideration for Tympanostomy Tube)
    3. If Tympanostomy Tubes not placed, recheck effusion every 3 months

IX. Precautions: Higher risk populations

  1. Infants under 8 weeks of age
    1. Associated with increased complications from Otitis Media
    2. All febrile infants under 4 weeks undergo Neonatal Sepsis evaluation (regardless of Otitis Media presense)
  2. Adults with recurrent otitits media (>2 episodes/year) or persistent Otitis Media (>6 weeks)
    1. Consider mechanical obstruction
    2. Consider naspharyngeal mass (especially blocking the eustachian tube)
