I expect this has been asked before but do asthma preventative inhalers cause reflux (GERD). I was changed to Fostair Next inhaler a few months ago and I have felt breathless and tight chested since and keep burping and coughing. Thinking it was my asthma I went to the doctors and he said my chest is clear and it was reflux. I have been prescribed Lanzaprazole which he wants me to stop on long term but I am not happy about that. I have had reflux in the past but not as bad as this. It just seems to mimic asthma symptoms with the breathlessness and tight chest!
