Lidocaine
"I have used these patches with great success for years but yesterday I was given the new Mylan brand and they are awful...they will not stick and I am allergic to surgical tape so can't keep them on.  They just plain will not stick except to themselves.  I am stuck with 90 patches that I most likely will not be able to use and I am going to be in pain all month until I can get my next RX.  You can bet I will ask for my old brand next time."
