Homatropine / hydrocodone
"After having no luck with the prescription Virtussin, I went to doctor and got Rx for hydrocodone/homatropine.  I was nervous about all the nausea statements, so I had a small snack before I tried it.  It did not completely stop the cough, but it certainly reduced it enough to let me grab a couple of hours sleep.  The directions call for 1 teaspoon every 4 to 6 hours.  Fortunately, I did not experience any nausea.  When I did wake up in the middle of the night, I usually stayed up for about 30 minutes drinking ginger ale, having a snack, and trying to cough up some of the phlegm.  All in all, I am pretty happy with this drug.  It is also possible that the Virtussin that I originally tried was just old."
