I am new to fostair and am hoping for a improvement from sybmbicort after a short try on seretide that didn't work for me. I have only been on it for 3 days now and also I don't want to get thrush so am swilling with mouth wash as I take my medication roughly the same time as daily hygiene. I don't know if this is a good idea or not. Does any one else use mouthwash to swill with and what are the chances of getting oral thrush on fostair. I am new to fostair and dont know yet if it will benefit me.
