I ordered Medline Remedy Barrier Cream. What came was not barrier cream but what they call Prevent Silicone Cream with zinc oxide. I decided to give it a try, as I figured it was maybe about the same thing. It works great! I use less than half an inch, putting it on first thing when getting ready for bed. That gives it time to dry some before I put the tape on.
I'm still using the first tube I bought on November 11th, and there is a lot left. I've ordered more in case they run out. In December I bought some real barrier cream as an experiment and found it did not help with the pain at all, so I don't recommend it.
So there you have it. Medline offers a new version of the Prevent Silicone Cream, but the version I am getting is cheaper, so I'll stick with it until they run out.
I hope this helps someone.
