Thanks for the query.
I understand your concern.
Usually twice a dose per day oxybutinin is enough in most of the patients as higher doses can lead to central nervous system side effects.
According to your age you can also prefer other anticholinergic drugs like Tolterodine or darifenacin etc.
So, please discuss these things with your doctor and follow his advice.
