Are you sure that you can put them on your ARMS? I used patches for years and the directions always said to never put them above the waist. "immediately after removal of the protective release liner the patch should be applied to an area of clean, dry, and intact skin.
The site selected should be one at which little wrinkling of the skin occurs during movement of the body, e.g. buttock, hip, or abdomen, and which is not exposed to sunlight i.e. those areas normally covered by clothing.
Experience to date has shown that less irritation of the skin occurs on the buttock than at other sites of application. It is therefore recommended to apply the patch to the buttock.
The area of skin should be nongreasy and free of irritation" I copied this from the estaderm manufacturers directions from an online place. I found the the butt worked best, below the panty line so it doesn't rub. Also, Hot showers, sweating, etc. can work against you. I live in Florida, US and never lost one. Is Estraderm one of those that is kind of "squishy" from a supply of liquid in the patch itself? There are MUCH better ones that are thinner, and have the drug fully contained in the matrix. They lay flatter and don't grab on your clothing. Maybe your doctor can switch you, if your answer to the above question is yes. Good luck.
