[|AI|]  Thanks for posting your query to Chat Doctor. As you are having couch for 3 weeks first I would suggest you some investigation.1.gram stain and Zn stain microscopy of sputum.2. Culture and sensitivity of sputum. It will help in detection of cause. However you can take syrup containing Ambrose, terbutalin and guaniphesin 2 tea spoonful 3 times a day, tablet cetirizine 10 mg with monteleucast5mg once at night and pantoprazole 40 mg once in morning.it will give you symptomatic repaid. Further treatment will be based on your investigation report because you have already taken antibiotic .feel free to ask if any query. Review me after report come. Regards, Chat Doctor.
