That’s the first time I have heard this med is same as diclofenac, an NSAID cream that I avoid because I also do not touch most NSAID’s. They are not the same drug, chemically. The brand name for diclofenac is Volataren, Trolamine is in the aspirin family of drugs which don’t seem to bother me. These are two different medications that may also contain similar inactive ingredient’s, but active ingredient is very different.
