jmoore I had a lingering cough for a long time over a year (almost 2). I was on Lisinopril for blood pressure. My doctor changed my script. I had the cough so bad at times that I could hardly talk without coughing. It affected my job. Every time I turned around, I was coughing with almost every breath. The script change made a big difference. Also, I have an upper denture that hasn't fit right from day one. If I use too much adhesive, it makes me cough. Almost all blood pressure medications side effect includes a persistent cough. My chest exrays all showed clear with no signs of pneumonia or anything else. I coughed so hard one day, I cracked 3 ribs. I have scoliosis (curvature of the spine) and believe me that didn't help. I rarely cough any more and am able to conduct business (on the phone a lot)and relax. A simple change of script may be all that's needed.
