I do. They are replacing Celebrex, which I had taken for a couple of years for osteoarthritis. When I first changed over, I noticed a return of the pain, but after about six months, I have to say that it is about the same as under Celebrex.
I am sure that there are other factors involved as well, but I have had the problem, with increasing effects, for about six years now so am very happy with this (apparent) non-prescription solution.
