Hello doctor, I have been suffering from chronic asthma for the past 10 years. I am presently using seroflo 250 and tiova 200 inhalers. Every two months I fall sick due to cough and chest congestion and have to take antibiotics. I wish to reduce my medications gradually as its not good in the long run. Is levolin inhaler safe for use, can it taken in place of both the above inhalers? Or are there any other alternative therapies to increase my lung capacity? I have also purchase airphysio from amazon for breathing exercises. Kindly suggest suitably, thanks!
