Wheezing from birth. From my life.

Dear Sir, I am not sure if it is too late, I have wheezing problem since I was a 6months baby. My parents tried their best to get my disorder resolved taking me to various consultants, However no change. Last, I met Dr. Raju in Raju hospitals for this wheezing problem. He had taken some tests on both my hands and then he suggested me to go with Cipla Inhalers. Since then I have been using CIPLA ROTOCAPS Seroflo 100. (Almost 15+yrs now), I know I cant live without this reliefer. If this medicine get extincted from the world, I am for sure I will die within a week of its extinction :) .. Now, this year, I had severe wheezing due to frequent travel and cold climate, though I live in Chennai. Can you suggest me what can I do.. Is it good to continue using Seroflo 100 rotocaps or I need to do extra medication to get rid of Wheezing from my life.
