Dear Sir/Madam, I Am Staying In Bangalore Currently And Getting

Dear Sir/Madam,
I am staying in bangalore currently and getting the frequent cough problems like chest congestion etc. When i go to my native in Rajasthan, I do not face any such problem. It looks like a bronchitis asthama. Sometimes I tend to use foracart with rotohaller and for the current month (winter) this problem is recurring fast.
What do you suggest me as solution. Though I dont want use medication permanently, any other way to take care of it? What are the side effects of using foracart with rotohaller ?
Thank You
