Last week, I went to my primary care doctor last week after 3 weeks of cough/congestion. She sent me for chest xrays and started me on Albuterol inhaler, ZPak antibiotic (Azithromycin) for 5 days and mucinex. The xrays came back negative for pneumonia but indicated lungs were minimally hyperinflated. I've never smoked. I feel a bit better but still have the cough.(4 weeks now). Would Erythromycin be a better antibiotic to stop this cough?
