question: hello doctor,my daughter aged 3.5 has been having quite a bad cough on and off since past 2 to 3 weeks along with some phlegm that she coughs up too.ive tried giving her bricanyl/levolin continously for 5 days after which it subsides, although not completely but after yesterday's holi,her cough seems to have gone up.this looks like its due to the change in weather here in delhi but plz do suggest a suitable medicine to arrest this .
