My wife who is 51 years old was diagnosed for symptoms of fibrosis (ILD) and has been using Wysolone steroids for last six months to control the continuous dry cough. The dry cough has since ceased and she has stopped taking wysolone. But wet cough with while phlem has started immediately accompanied by weakness. She has been on relent tablets since then for last one week which is effective for only 5 to 6 hours. Pl advise.
