Most of them complain that even after using the inhalers, i am not getting releif. but the reason is improper use of the inhalers. even i use to not use properly. after doctors advice i discard 1 puff outside, take a deep breathe 2-3 time and leave the air out. then take a deep breathe, take the fumes inside, hold the breathe for some times and then remove the inhalers.
