Hi, I'm new to the forum. I've had mild asthma from childhood, characterised by repeated bronchial infections which have diminished with age. Some years ago I was prescribed "Seretide" which had the strange effect of changing my "wheezing" to coughing. I didn't take too much notice at the time. More recently I was prescribed "Fostair" which I thought increased my coughing. I spoke to the "asthma nurse" about this but she convinced me to persevere with it, which I dutifully did. Six weeks ago I developed a nasty cold with a cough so severe that I pulled all my intercostal muscles and self-medicated with codeine to try and suppress the cough. (There was no bacterial infection and phlegm was clear.) So, six weeks go by with no let up in the cough and I decided to stop taking the Fostair. My cough all but disappeared within 24 hours. I'm convinced that Fostair was the culprit. Has anyone else experienced this effect? Also, it's almost impossible to clean off the spacer that I use.
