Thanks for the warning. I often see recalls or little known problems with drugs. Recently one manufacturer's blood pressure medicine has been recalled a few times. Sometimes natural support just doesn't help or help fast enough. It's bad to have to rely upon pharmaceuticals.Rinitadine is a stomach drug that relieves heartburn, but it has recently been found to contain a small amount of N-nitrosodimethylamine (NDMA), an impurity that causes cancer. Most of the ranitidines on the market seem to have the same problem.
