Can anyone tell me the history of the U values of commercially available insulin the USA?
I know I took U80 and U100
I believe my mom used U40
and I have seen pictures of vials of U20
Does any know was U40 a commercially available insulin or did I dream it up? Also what are the other insulins available? I knwo U500 is used by some, are there others?
Also how would describe the difference in U values? I have understood it to mean that a person using U20 would need to take 5 times the volume of U20 in order to match the potency of U100? Is that a correct statement?
Inquiring minds want to know?
thanks for any help.
