Jayne, Mother's neurologist prescribed Ditripan, but she had had wetting accidents occasionally, so it was for that too. There is also Detrol, but these might be more medication that your Mom needs. The Ditripan has been very effective most of the time, some days it seems to stop working early in the evening. She takes one tablet first thing in the morning. You should check with your Mom's doctor. He might even be able to give you some samples to try before you actually have to get a full prescription filled. Hope this helps. Eleanor
