Mom takes meds In AM and PM, which I set up in her pill box. She has gotten to the point that she can't take out of her weekly pill box so I have to put in AM in morning and can't put PM until later that night. If I leave the PM in daily pill box she will take everything and then accuse me of not giving her meds.
Then it was my job to take the pills out and give them to my husband at the appropriate times. He could not be relied upon to do it correctly himself. I see that my sister treats my mother's (92, dementia) pills the same way, so that is what I do when she visits me.
Since Mom lives with you and you have a caregiver with you when you work, this might be the most reliable method for you, too. Just give her the pills she needs to take at the appropriate time, and don't confuse her with the pill box.
I served my husband's in a little dish, along with a side of yogurt or applesauce. He first arranged the pills in the dish, grouping the small ones he liked to take together, then he took a group in his spoon, dumped it in the other dish, and scooped up pills and yogurt/applesauce together. He felt in control of taking pills the way he wanted to, but I was in control of what pills he took.
[I wish someone would do this for me. Sigh. I'm having a horrid time remembering to take my own pills on time. :( ]
It is a reminded to anyone who is with Mom, that it is time for her pills. She gets all her pills with applesauce. We used to give them to her with yogurt, but the neurologist said that was not a good idea as the yogurt coats the stomach and keeps the meds from being absorbed completely. Pretty much the same with any dairy, like puddings. Applesauce is best.
Your mom cannot be expected to keep track of her own meds anymore. Prompts may help occasionally, but if she needs her meds on time, best someone make sure she gets them to be sure. Good luck!
Hope this helps. Good luck!
When I certain point in dementia is reached the only safe way to administer pills is for someone to hand them to the person and watch while they are taken. Sad, but that is how it is.
