First of all NEVER EVER place patch on scratched or irritated skin... unless you want to O.D.
I always ***LIGHTLY*** clean the area with alcohol on a qtip.. and then u can either put a piece of either KT Tape over the patch or I use Leuko Tape (Google it). I can assure you!! That patch will stay on through shower after shower no problem. Round off the corners of the tape too!
