What people are not told in this country (and I wasn't aware of until literally last month) is that there is a brand of insulin which is available in both long and rapid acting versions, that can be purchased in many (possibly most) states WITHOUT A PRESCRIPTION for less than $25 per type per month.
This is not any kind of "good RX coupon" thing, either.
It's call Novalin. Novalin N is long acting, Novalin R is rapid.
If you are diabetic, obviously talk to your Dr about switching, but even WITH insurance, my prescribed insulin was $600 per month.
My Dr wasn't even aware of this brand's existence since she was hamstrung by the "preferred" insulins of various insurance companies and the existence of it is mostly covered up by them.
As much as I despise Wal-mart, this is where it's available for the least amount.
