I have tried the generic patches produced by your company, since my insurance will not cover the name brand patches. After using 3 full boxes of the patches, I have declined to refill the prescription, simply because I cannot keep the patches on. Some fall off after only a few minutes, and I have never kept a patch on for a full 12 hours. I would greatly appreciate some improvement in this area. Is there a way you can improve the sticking quality of your generic lidocaine patches?
