      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

            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

      5. Cefpodoxime (Vantin) 10 mg/kg divided twice daily for 10 days
   4. Third Line

      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
6. 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)
7. Protocol: Topical agents if patent Tympanostomy Tubes

   2. Ofloxacin (Floxin Otic) 5 drops (10 drops if over age 12) twice daily for 7-10 days
8. 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
9. 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)
