Overactive Bladde
"Started taking oxybutynin as I was having frequent need to urinate terrible bladder spasms/pressure/discomfort and need to urinate after I had already gone. It was almost constant and depressing. Sometimes I used heating pad on pelvis to relax as much as possible. Started taking oxybutynin but it wasn&#039;t helping  great deal until I started taking the extended release. That has been a life saver for me. It started working within 2 weeks even though It could take up to 6 weeks to kick in. Maybe because I had already been taking the regular oxybutynin a few weeks prior. Either way a miracle and don&#039;t think I will have to increase dose at this point. I am drinking plenty of water and trying to eat plenty of fiber to avoid side effects."
