Thanks for your question on Health Care Magic. I can understand your concern. No, this is not correct way to treat pneumonia. You already completed the course of broad spectrum antibiotic and now again develop cough and fever. So possibility of worsening of pneumonia is more. So better to first isolate the causative organism and then start appropriate antibiotic treatment. So consult pulmonologist and get done sputum culture and sensitivity report. If sputum is not available then get done Bronchoscopy and BAL (bronchoalveolar lavage) analysis. Culture report will isolate the causative organism and sensitivity report will guide about effective antibiotic treatment. By this we can achieve quick recovery with minimal antibiotics. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
