I'm on this nearly script-stuff. I've only found it at hospital pharms (Kaiser)
Glycolix or somthing? It's got 4% instead of the lower percentages. It's great stuff, I use it 3X's a day. 12 bucks a bottle for the wash, they also have a 5% pad that drys me out like hell but clears you up like nothing else.
Glycolix is the name brand. I think that's what it is called, will have to check the neam at home.
