"I have been using Xulane for some time now.  Over a year I think.  Before that I used the Ortho patch.  I loved the smaller size of the generic brand and up until the last 2 months I had not had any issue.  Suddenly it's not been sticking like it use to and it's causing a rash like a chemical burn and the itching is present.   I thought last month's could have been a bad batch but after I moved locations (I use to move from hip to hip) to ensure I hadn't irritated my skin,  I am wondering if they changed a filler or adhesive."
