hubby does keep them on until he does not see any other medicine in the patch but it is dangerous. No-one says anything about how to keep them on. His keeps falling off which gives him an excuse to put on another one. How in the world do you get them to stay on? Osto-bond or Tegaderm or Torbot Skin? Which is best and I guess Amazon is where I would have to get it cause i went to every place in my tiny town and they do not have it. Any suggestions besides what I have already tried which is every tape known to man that Walmart sells that i can pick up right away? Have not tried duck tape yet and i know a hair dryer is bad(read the other forums online) Thank you and God Bless
