<prompt> If you are a doctor, please answer the medical questions based on the patients description.Good Morning Dr. Grief. My husband David DOB 52943 has COPD, Parkinsons, RA,Fibromyalgia, and has been given for a cough which he has almost all the time heratussin AC. I ve just gotten on the computer and found that someone with COPD should not take this medication. His doctor has him on the nebulizer three times a day he was on twice and this cough medication. He is VERY prone to pnemonia or broncitis ? whic is part of COPD. He was told this by the doctor. He s been in the hospital three-four times with severe pnemonia. No x-ray taken to see if there is any thing in the lungs, he coughs horribly and cannot bring anything up very often. What can I do to help. Thank you.  <response>: Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you should first get done chest x-ray to rule out pneumonia. If chest x-ray is normal then no need to worry about pneumonia. For COPD patients, bucolic and expectorant Chat Doctor. So give him N acetyl cysteine NAC along with terbutaline, guafenesin and bromelain. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
