Wheezing and cough. Inhalers required?

My 6 year old daughter is suffering from wheezing and cough. On and off since last 2 years. She was absolutely fine during summer months and neubilization was not required but condition worsened during winters in Delhi.Doctors have diagnosed it as allergic bronchitis.  She is been given budesal 0.5 and salbair 0.31 and 5ml montair syrup Her conditions improves a lot after neubulization.. Now the doctor has advised to give budecort inhaler 2 puffs twice a day and she is taking it. She is advised to stay away from dust, moulds, cold food and water .Her allergy panel report was normal Serum Ige = 10. The paediatrician has diagnosed as allergic bronchitis. Pls advise if the paediatrician has given the right treatment? Are the inhalers safe without any side effects.? Will the child get dependent on inhalers? Can steroids slow the growth (height/weight)? For how long are the inhalers required ?
