It appears that statins can cause a dry cough and mucous in the throat and chest as an after effect in some individuals. All last year I had these symptoms and it was exhausting and caused the loss of my voice nearly all last year. Once I started taking MusinexDM the cough stopped, the mucous was removed and my voice is now fine. But, I take MusinexDM every morning now. Is there a problem if I do that?
