I had a breathlessness after I journeyed by train for 12 hrs (hyd-mum ). Oxi conc. Was 92 %.after treatment 4 days 1 augmentin tab + duolin .25 +budecort .5 in a week I recovered. I was prescribed sequadra inhaler 1/day by chest specialist (dr. Nair -nanavati hos. Mumbai) since last 2 years I use sequadra but as such I don't feel any significant/really -comfort-breathing. It's a period costly inhaler comparatively. I was asked by Dr. Not to stop this. Where as if I take tab. Derifyline 150 retard, the cough loosens & in 2-3 days I breathe very comfortably. The problem I get when humidity is high (mumbai). Pl advise is this sequandra worth continuing? What is the speciality of this inhaler comparative with other inhalers in india not so very costly?
