i was put on propanalol a few years ago because of severe anxiety but for a long time I have had a slight wheeze and its not connected to breathing difficulties or COPD or anything like that. I had a blood test and doctor was happy with it and am not in any way breathless. I have stopped taking one capsule every third day and my slight wheeze is better. I take 25mg amitriptyline every night and am fine with it. My problems with anxiety was always related to my son’s health. Type 1 diabetes and multiple sclerosis. That will never change I can just handle it better I think. does anyone find they have a wheeze on propanalol I think it was too big a dose for me
