Ear infections can last anywhere from a couple of days to a week or so depending on how fast the infection was caught by a doctor and what treatment was used. Antibiotics can help speed the healing process if it is a bacterial infection, however if it is viral, then this approach won't help. Also antibiotics won't remove the inner ear fluid.
The doctor will probably suggest a routine of cleaning the ear and putting antibacterial ointment on it. You'll need to have a parent check in with the doctor again if the infection doesn't start going away after 2 days. But if you take care of the infection, it probably will go away completely in 1 to 2 weeks.
