My Mother, 89 Years Old Has Alzheimers And Is Incontinent.

My mother, 89 years old has Alzheimers and is incontinent. She has used Toviaz and other medications but they caused her to have a weak urine stream and she still had accidents. So now she is not taking anything but I saw an ad for Azos Bladder Control and wanted to know if this would work for her. The only other medication she takes is her thyroid and a very small amount of estrogen.
Thank you.
