Age Otorrhea Severe Symptoms (unilateral or bilateral) Bilateral without Otorrhea Unilateral without Otorrhea
6mo-2y Antibiotics Antibiotics Antibiotics Antibiotics
2=≥2y Antibiotics Antibiotics Antibiotics or observation period Antibiotics or observation period

Also Consider In:

  • Age <6mo
  • Ill-appearing
  • Recurrent acute otitis media (within 2-4wk)
  • Concurrent antibiotic treatment
  • Other bacterial infections
  • Immunocompromised
  • Craniofacial abnormalities

Wait-and-see antibiotic prescription (WASP)

  • Rather that routine perscription is an option to avoid over use if the patient does not meet any of the prescription criteria[2]
  • If symptoms worsen or persist for 48-72 then caretaker fill the prescription
  • Fever (relative risk [RR], 2.95; 95% confidence interval [CI], 1.75 - 4.99; P<.001) and otalgia (RR, 1.62; 95% CI, 1.26 - 2.03; P<.001) were associated with filling the prescription in the WASP group

Antibiotics Options

  • Consider treating for a standard of 10 days as opposed to a shorter duration of 5 days to reduce treatment failure in young children[3]
    • Treatment failure for 10 day at 16% and for 5 day at 34% for amoxicillin-clavulanate
    • RTC of 520 children aged 6-23 months

Initial Treatment

  1. Amoxicillin 80-90mg/kg/day divided into 2 daily doses 7-10 days

Treatment during prior Month

  1. Can use Amoxicillin as same dosing as initial treatment
  2. Cefdinir 14mg/kg/day BID x7-10 days
  3. Cefpodoxime 10mg/kg PO daily x7-10 days
  4. Cefuroxime 15mg/kg PO BID x7-10 days
  5. Cefprozil 15mg/kg PO BID x7-10 days

Treatment Failure

defined as treatment during the prior 7-10 days

  1. Amoxicillin/Clavulanate
    • 80-90mg of amoxicillin per kg/day
    • Clavulanate increases vomiting/diarrhea
  2. Ceftriaxone 50mg/kg IM once as single injection x 3 days
    • Use if cannot tolerate PO

Penicillin Allergy

  1. Azithromycin 10mg/kg/day x 1 day and 5mg/kg/day x 4 remaining days
  2. Clarithromycin 7.5mg/kg PO BID x 10 days
  3. Clindamycin 10mg/kg PO three times daily
