Chlorpheniramine / hydrocodone
"I was having coughing episodes about 3 hours long. I coughed until I vomited, and even until I lost control of my other bodily functions (both of them). I basically did not sleep more than 3 hours a night (if that) for a week and a half. Since I can expect this cough for another 4 weeks to 4 months, I broke down and gave this a try. It is a testament to the sheer physical force of the pertussis cough that Tussionex only stops it by about 80%. But that 80% makes all the difference! I am sleeping adequately and can keep food down. The unpleasantness that goes along with taking opiates is far, far preferable to this vicious pertussis cough."
