Hard to say: The best way to anticipate success of an antibiotic is to have a culture of the germ where sensitivity is tested. Without that, you rely on clinical change. The germ in these infections has had a head start creating the problem. I would expect a decline in fever within 24/36 hrs after starting the med as a good sign it will work. I would not expect it to change the symptoms in 4 hours.
