Randomized Controlled Trial Clinical Trial
Efficacy of 20- versus 10-day antimicrobial treatment for acute otitis media.
The purpose of this trial was to determine whether 20 days of antimicrobial treatment is more efficacious than 10 days of treatment for acute otitis media (AOM) in clearing middle ear effusion and preventing recurrences of AOM, and whether changing to a beta-lactamase-stable antimicrobial agent after the initial 10-day treatment with amoxicillin for AOM is advantageous. ⋯ More children were effusion free by the day 20 visit if given antimicrobial treatment for 20 days rather than for 10 days, but this advantage was present for only a short time; by the end of the 90-day study period, the treatment groups were comparable with regard to effusion status. Recurrence of AOM during the study period was not prevented by the additional 10 days of treatment. Routine use of an additional 10-day course of antimicrobial treatment is therefore not recommended if a child is symptom free after the initial 10 days of treatment for AOM.
