pneumonia
"Unfortunately, although Azithromycin is a very good antibiotic, it is prescribed mostly for viral infections in the acute care setting based on people's symptoms and not on x-rays of the chest. If you have bronchitis which is mostly viral, Azithromycin is not going to do you any good. The color of the phlegm does not correlate with bacterial infections and therefore should not be used as a criteria for prescribing antibiotics. Fever does not mean much initially but after a URI or brochitis for 7-10 days fever is more significant and a bacterial source should be assessed. Sinusitis is not a shoot from the hip diagnosis. There are four pairs of para nasal sinuses and the doctor or PA cannot look inside your head. Do an x-ray or CT. Beware."
