Fentanyl
"This is so much better than taking pills all day everyday! The best advise I have for people that have problems keeping the patch on is this: I buy the large waterproof bandaids and I buy the generic patches (not the kind with the gel). As soon as you put on a new patch, put the waterproof bandaid over it. Dont wait until it is falling off to put the bandaid on. The Nexcare brand or the generic CVS waterproof bandaids are the best. I haven't lost a patch early since I have been putting the bandaids over them. The best part is that I get 10 patches a month and the bandaids come 10 to a box. It's perfect! This works great in the summer time too. I live in South Louisiana so trust me, I know what I am talking about."
