Diclofenac is 1 of 6 drugs in my compounded cream. It also contains ketamine, gabapentin, and 3 other things I cannot remember off the top of my head...It works great for getting rid of some of the hypersensitivity I get on top of my foot - and takes a few days of use to get the full effect. If I use it too often however, my skin doesn't like it so much - which is why I usually use that during the day and the flector patches at night.
