Otitis media is a common pediatric complaint seen in the primary care, urgent care, and ED settings. Recommendations for timing of treatment and deferral of treatment have emerged over the last several years, as have recommendations for regimens for recurrent infections in the age of resistant organisms.

When to consider observation over antibiotics:

If symptoms <48 hours, no severe pain, and fever < 39C and child is 2 years or older (either unilateral or bilateral AOM) OR unilateral AOM with symptoms <48 hours, no severe pain, and fever < 39C and child is 6 months to 2 years
If observing, consider either a prescription that parents can fill if symptoms persist or ensure prompt primary care follow up

Initial treatment

High dose amoxicillin (90 mg/kg/day divided BID)

If true penicillin allergy, can use cefdinir or cefpodoxime if tolerated or trimethoprim-sulfamethoxazole or a macrolide (e.g. azithromycin) but rates of resistance are higher
Cefdinir and azithromycin are the most commonly used
Levofloxacin is also an option for age >8 years

Recurrent Otitis Media

If less than 30 days from initial treatment, presumed to be persistent

If previously on amoxicillin, start amoxicillin-clavulanate (extra strength suspension has highest amoxicillin to clavulanate ratio and should be used)
If previously on amoxicillin-clavulanate, ceftriaxone either for 3 days or 2 doses 36 hours apart

If greater than 30 days from initial treatment can treat as new episode (so amoxicillin unless previous documented resistant infections)

Duration of Antibiotics

Less than 2 years, 10 days
2 years and up, 5-7 days

Other Considerations

Amoxicillin-clavulanate should be used as an initial agent if there is concurrent purulent conjunctivitis
Children with tympanostomy tubes and purulent otorrhea may be treated with otic fluoroquinolones (with or without dexamethasone), as long as debris does not obstruct entry of antibiotic drops
Remember that the otic canal and TM can become red with fever and non-purulent effusion is common with URI
Remember to treat pain and fever!
