Oxybutynin
"mary4589 --along with your dry mouth, did you have any dryness of skin at the fingers and palms of your hands --I mean severe wrinkling of fingers and palms like you have been in the tub for a week? I was 2 weeks on this med and it's been 4 months off and still have extreme dry mouth. I have cut off all other meds and vitamins to figure out what is causing this dry mouth and hands, but after reading the reviews it could be this medication has permanently cut off our saliva system.  for all others who are thinking about taking this med - think about how this will not only affects your bladder problem but everything to do with water in your system."
