Hi Doctor, My son is 9 yrs old and suffers from cold climate,dust allergy with difficulty in breathing at night/early morning times. We hear wheezing sound also..we used to have 100mcg budecort inhaler 2-3 puffs,but recently we have to nebuluze him with budexort .5mg and levolin .63mg mixture resuples to make him sound sleep... Iam quite worried on this change and his health now...Please advise on which method is better and how to avoid both of them in near future and improve his health better. Thanks Sankar
