Likely causes of amoxicillin-unresponsive AOM include infection caused by amoxicillin-resistant bacteria, inadequate dosing or absorption of amoxicillin, poor penetration of amoxicillin into the middle ear space, reinfection with a second organism, and AOM caused by viral infection or viral and bacterial co-infection.How long does it take for antibiotics to work for bacterial infection?
"Antibiotics will typically show improvement in patients with bacterial infections within one to three days," says Kaveh.
