overactive bladde
"This drug was the best one I have ever taken for overactive bladder.The only other drug I have taken was Vesicare.  It helped some  the side effects. The effectiveness of Vesicare was marginal at best.  However  the side effects of Oxybutynin for me were intolerable.  It made extremely sleepy,  had difficulty driving, no appetite and fatigue beyond belief. I was only on this drug for one week. These side effects lasted a little over a week but are now very slowly going away.  I am switching to generic Detrol and hoping for the best."
