Cake: I have a friend that is on Oxycontin 80mg also. He told me that when the itching becomes a problem for him,along with taking the Benadryl he said sometimes it helps to take a paper-towel and wipe the outer coating off. With just a little damp water. I am talking about doing this on the Oxycontin. It does help with the itching. Also it does dot take away the stregh of the pill. I do think you should talk to your Dr about this situation before doing this. I also do think the sun could maybe affect you? However I do not know if you are a sun person? Take Care! Breezy55
