I have been using Humalin R the past few weeks in my pump and it has been working really well. In fact, better then apidra or humalog/novalog have ever worked for me.
Anyway, all forms of regular insulin are apparently "tier 3" for our prescription coverage which is a really high copay (it is actually cheaper to just buy without insurance from target). It looks like I can get Relion R from Walmart and it is made by the same manufacturer as the normal Novalin R.
Would you try it? I figure the worst thing that happens is it doesn't work as well and I am high or low for a few days.
