Oxybutynin
hyperhidrosis
"I am a 55 year old woman who has suffered from sweaty hands and feet for as long as I can remember.  Also the icy feet and hands while still sweating. It's been a lifelong struggle.  I've tried everything over the years and nothing worked. About a year ago I watched an episode of diagnose me.  Long story short she suffered from hyperhidrosis. The cure Oxybuten.  It's a bladder control medicine.  But for me it's lifesaver.   I have warm dry hands and feet 95 percent of the time.  It's changed my life."
