Rose, Ask his doctor about Detrol or Ditripan. Mom takes Ditripan and it works pretty well. Sometimes there's a problem late in the afternoon or evening or when her medication wears off and she gets shaky. We tried Detrol, but Mom has strange reactions to some meds, including this one. But, I'm sure you know that what works for one PWP doesn't always work for another, so check with his doctor and good luck. Eleanor
