If You Give Amoxicillin/Clavulanate to Six- to 23-Month-Olds with AOM, 10 Days Is Preferable to Five Days
Am Fam Physician. 2017 Apr 1;95(7):457.
Is five days of amoxicillin/clavulanate (Augmentin) non-inferior to 10 days of amoxicillin/clavulanate in children with acute otitis media (AOM)?
These authors begin with the assumption that we should treat children who have AOM with amoxicillin/clavulanate. They demonstrated that outcomes were slightly better with 10 days of treatment compared with five days of treatment in this group of six- to 23-month-olds with rigorously confirmed AOM. The greatest benefit was in children one to two years of age who had more severe pain and fever. In children with less severe symptoms, observation should still be the preferred option, as recommended by the American Academy of Family Physicians guidelines, accompanied by appropriate treatment of pain and fever.

A previous study by the same lead author (N Engl J Med. 2011;364(2):105–115) found some support for antibiotics in children younger than two years with AOM for the outcome of sustained resolution of symptoms at 14 days (67% vs. 53%; P = .04; number needed to treat [NNT] = 7), but it found no significant difference at two days, four days, or seven days. Children who received amoxicillin/clavulanate had more diarrhea (number needed to treat to harm [NNTH] = 10) and diaper dermatitis (NNTH = 6). Although that seems like a draw, at best, the authors concluded that amoxicillin/clavulanate is appropriate for treatment of AOM.
In this study, the authors identified 520 children, six to 23 months of age, with AOM based on the presence of less than 48 hours of symptoms, a score of 3 or more on a 14-point AOM symptom score, the presence of middle ear effusion, and bulging of the tympanic membrane. A total of 515 were randomly assigned to receive 10 days of amoxicillin/clavulanate or five days of amoxicillin/clavulanate followed by five days of placebo. The dose was 90-mg amoxicillin and 6.4-mg clavulanate per kg. Approximately one-half of the children were six to 11 months of age;
