Oxybutynin
"Did no one else experience what happened to me? I started on Oxybutynin 5 mg twice a day (oral); there was a significant improvement in bladder control. I used less pads and thinner-type pads. HOWEVER, the side effect I experienced was exceedingly annoying: my nose stayed stuffed up constantly; I'd wake up with cotton mouth; lips cracked and bleeding from not being able to breathe through my nose. It took a large application of Vicks Vaporub into my nostrils; pouring of hot water into them; holding hot washcloths on my sinuses for an hour at a time; and using inordinate amounts of saline sinus spray to finally clear my nose. When I stopped taking Oxybutynin, my nose became clear within a few days. Never again will I use Oxybutynin."
