I have gone through your query and understood your concerns. I think bacteria is resistant to azithromycin
and if it is the reason you need to change the drug. I suggest tab.levofloxacin
to you. As it is a prescription drug you need to consult your doctor for this. You need to have an chest xray done to rule out other possible causes. I also advise you to take tab.pantop for 7 days once daily. Thank you.
