My Mom is bed fast and has dementia. I use both clear and skin colored bandages. She just came out of the hospital with her whole arm red and swollen from infection. She is a constant picker. She has picked and unraveled her sweaters that she wears. I have wrote on a bandage do not remove and she still picked it off. She only wears dresses and sweaters. She has picked 4 bandages off in the last 12 hours. I really thought the clear skin tight bandage that the hospital put on her would stay on but it didn't. She has pulled 5 catheters and 5 ivs out. I'm hopeless!
I might also suggest that you discuss anti-anxiety medication. My cousin constantly picks her nails and bites them down to the nub when she is not on Cymbalta. When on this med, she doesn't do it at all! It makes a huge difference with her.
Sadly, wrappings, bandages, tape, etc. never worked with her even a little bit.
