Have only been on patches for about four months now, so I am not much help in regard to the OP question. My wife has been using generic patches, and she has had a terrible time with them coming off. I learned a trick from her when it comes to using Nexcare absolute waterproof tape to secure the patches. She uses quite a bit to cover her generic patch, and I use a tiny strip to barely cover my Vivelle patch. Too long and the tape tends to bunch. The ads says it is waterproof, breathable, and sticks when wet. I have been outside in the heat a lot this summer and only had one time where it peeled off.
