I have been on Fostair now since June 2016. I have noticed a big difference in my breathing. It is much better, however constantly getting oral thrush. I got it cleared up with Fluconazol and then started to take it through a spacer. No different. I have a drink and garggle straight after taking it but makes no difference. I have tried all sorts. I am loath to go to the doctor again as she will probably change it and apart from constant oral thrush which is quite sore, it has made my breathing and staying well chest wise much better. Any ideas?
