If your doctor is worried that you might have pneumonia
, a chest x-ray can look to see if there's an infection, especially for
those who have coughed for
more than 3 weeks.
With a viral bronchitis, you should avoid antibiotics especially zpacks (Zithromax / azithromycin) which are overprescribed for these symptoms , and can lead to side effects and adverse drug reaction such as rash, antibiotic drug resistance and yeast infections.
