What if ciprofloxacin doesn't work for an ear infection?

Bacterial infection?: First, is the diagnosis correct? Most upper respiratory infections are viral, particularly in adults. Because it is unlikely that a culture was taken, a physician will select an antibiotic empirically. That is, he or she will choose an antibiotic that is pharmacodynamically the best. Finally, if it is a bacterial infection, it may be that Cipro (ciprofloxacin) is not effective. Need a correct diagnosis.

Other choices : If the diagnosis is correct, the chances of antibiotic failure with the first drug runs about 5-10% for any drug.Since there are other meds available, another can be selected.
