There are cough syrups that do contain things such as oxycodone and just about any other actual strong narcotic that could possibly work for you.i would just speak with your doc about it.since you were already on one of the stronger narcotics already that contain hydro,switching to something different,or just the oxy based cough syrup might control things a bit better.I really would just ask your pharmacist first about this and then with your doc.the pharms know sooo much more about actual meds and how they work than any doc out there.I always ask my pharm any actual med questions as they just know so much more than most docs.good luck.FB
