I was wondering if there were any other parents out there who have a child who is sensitive/intolerant to inhalers? My son, 4yrs old, has an intolerance or sensitivity to most of the inhalers. He gets very tired, irritable and pale. At first the paediatrician and I thought it was worsening asthma but it has become clear over two years of experimenting that there is something in the inhalers which bothers him. The hospital says this is very rare but is as a result of my son being hypersensitive. He is now on Singulair and we hope he responds better. Has anyone else had this experience?
