For the last 4 weeks i have been severe breathing problems. Last night it was so bad that i had to visit the hospital. They did x ray, blood test and ECG and all were clear. Eventually the Doctor gave me "Carbocisteine", has anyone tried this and does help with clearing chest to ease the breathing problem.
Hi Surinder 
Carbocisteine works to loosen the mucus/phlegm that builds up in your lungs, throat and/or respiratory tract.
It’s a strange thing because it only seems to work on some patients and not others, I was prescribed it and it didn’t do anything to clear my chest.
I attend a local pulmonary rehabilitation class and, from chatting with other patients over the years, approximately 50% find it works well, whereas t’other folks find it useless.
All I can say it try it and see if it works for you
