Hi, I am 48 years old, an Asthma patient for long 10 years, previously it was seasonal,, with climate change, now it happens through out the year,, even after dieting as per my Alergy test,, at the beginning I was given Decaden & Deriphylin injections,, then other Doctor changed to Salbutamol inhalers, later on seroflo250,, when those were not enough ,, I started on Duolin & Boticort Nebuliser,, But now its only giving me 18 hrs of relief,, is there any other medicine that I need to take alongwith ?
