Cough
"I got some relief from constant dry cough but I wouldn&#039;t say it&#039;s brilliant although I am asthmatic too.  This cough however  was not my normal now and again asthmatic cough.  Once I took the dextromethorphan I had bad diahorrea.   I have found I am now allergic to lots of medication that I never used to be prior to early menopause and and asthma. I  won&#039;t be taking again unless I am very desperate."
