97 year old mother urinates every 15 minutes. She has been to a urologist who gave her Myrbetriq which is not helping. Thoughts?

Sodas and tea aggravate the bladder and make you go more often.

She may not be emptying her bladder. She may only go until the "urge" feeling goes away. Have her sit a little longer. She will probably get that urge again. A member suggested that you lean forward while sitting, her daughter had MS and this is what she was told.

If she is not fully emptying her bladder each time and she is sitting in a chair most of the rest of the time try changing her position before she gets up. Often a change in the way someone is sitting will allow the bladder to empty more fully. I could get my Husband up from his chair and to the bathroom, did that every 90 minutes or so, and if he had been in his recliner for a while as soon as he sat back down again within 10 or 15 minutes he would be wet. I got into the habit of changing the position of his recliner for a little while before I would get him ho to change him.
And a quick question...every time she gets up to go does she actually urinate or is her underwear (pull up or any other product) wet when she gets up. It is possible that she does not "know" that she does not have to go.
If she is wearing a Pull Up incontinent type product if getting up and getting to the bathroom is stressful or dangerous then just let the product do what it is supposed to do...absorb urine.

My husband who was going to the bathroom every hour on the hour to pee, was put on just about all of the bladder spasms medications,(including Myrbetriq) and none of them helped. His urologist then put Botox in his bladder as that is supposed to help calm the bladder. Unfortunately that didn't help either, and since both my husband and I were not getting any sleep, the urologist recommended that my husband get a supra pubic(permanent)catheter put in, which we agreed to, and for the first time in about 8 months, we were finally able to sleep through the night. It was a Godsend for sure, and all I had to do was empty his catheter bag twice a day, once in the morning and once before we went to bed.
And while I realize that the permanent catheter is not for everyone, it sure made my life a whole lot easier while caring for my husband. I wish you the very best, as I completely understand how very difficult your situation is.

Do you mean, gets up and goes to the bathroom every 15 minutes, or wets her clothing and furniture or her Depends, or what is happening? Does she know she wants to go? What has been her normal bathroom-going routine? Has the frequency increased gradually, or suddenly? Is she upset about it herself, or does she think you're making a fuss about nothing?

I imagine her neurologist has already asked these and more questions, and will also have run various diagnostic tests too - I'm only asking for a clearer picture of what practical ideas might help AND be acceptable to your mother :)

Having a similar problem with my mother. Tried Myrbetrig,made her constipated. Just using pull ups with extra ansorbant pads.

When my mom took meds for this condition, it took about a month to work! Even then, it was only a slight improvement. Her nurse said that surgery drinks and food causes more frequency of urination. Mom loved Ensure, which is loaded with sugar, so we cut back on the drinks and it improved a bit more. .

I have the same problem, so I wear Depends.
