Sir, my son 21 years old had cold and cough couple o weeks back. Doctor prescribed augmentin 625, pulmocare, zedex syrup, otrivin nasal spray and esmeprazol for 7 days. He was tested covid negative. Fever, soar throat, runny nose are gone now. However, even after 12 days frequent coughing is not subsiding. Other doctor suggested ascoril ls with allegra m which has been taken for last 5 days. He is still having blocked nose and with frequent coughing and thin transparent white phlegm is coming out. He has past record of allergic nose blocking problem which gave coughing problem for long couple of years back. Could you please advise to alleviate coughing at the earliest?
