HI, I Am Caring For My Mum Who Is 82.

HI, I am caring for my mum who is 82. She is taking Ditropan 10mg 1 per day for her incontinence. Is there anything stronger for her as when she wakes up during the night to urinate or first thing of a morning, as soon as she stands up she just cant stop urinating and the it is a change of sheets and change or shower her . Can you share your opinion with me please?
