monitoring: Patients with acute otitis media should be reassessed after 48 to 72 hours. By this time, there should be clinical improvement in the signs and symptoms of infection, including pain, fever, and erythema/bulging of the tympanic membrane. If the patient has not responded and antibiotics were withheld initially, they should be instituted now. If the patient initially received an antibiotic, then the antibiotic should be changed (Table 126-1). Most children will become asymptomatic at 7 days.
