"i&#039;ve been using the butrans patches for the past 6 months. in the beginning everything was wonderful and breakthrough pain was nonexistent. i then began having more pain and my doctor put me on norco 10/325 3x daily. it was then that i developed rashes, itchiness and an intolerance to both medications, which my doctor said isn&#039;t that uncommon. now i&#039;m on 20mcg/hr and life is good again."
