i am an asthmatic. i was diagnosed at 14 yrs of age. it exacerbates in cold climates and when exposed to dust. right now i am 26 yrs old and i study in a cold place. my asthma is pretty bad now, with frequent wheezing and dyspnea . i was placed on seroflo powder inhalors, and it reduced dramatically, with no episodes. i tapered down the meds. now,after 2 weeks, the asthmas is back, and i was wondering if there were any side effects to prolonged usage of this medicine. kindly advice...
