When my cough started after about 6 months after I was diagnosed I wasn’t sure whether it was the IPF cough or just a normal one. But it never left. so I guess it is the IPF cough. I have jut started a clinical Trial on the IPF cough in Sydney, Australia. I’ve been on some medication called Ifenprodil for 8 weeks now and I definitely feel that my cough has improved immeasurably. I still do have an occasional cough, but I’m pretty sure that is due to the cold that I caught. It is so nice not to be constantly coughing. I have another 4 weeks to go on the trial.
