What type of insulin are we talking about
? Personally, I found a difference between Lantus (insulin glargine) and Levemir (insulin detemir). The rash thing I've encountered with Lantus and the reason I switched to Levemir. I understood it then as a "Ph level" thing, with Levemir being less alkaline.
From what I know, GLYCEROL (not different than glycerine) is only in the Levemir Penfill and not in the vial of Levemir insulin. Guess the cartridges in those pens needs glycerol for viscosity? PH of 7.4
Lantus, however, has glycerol in both vial (85%) and syringe (85%). Ph of 4.
Edit Note: glycerol & glycerine are the same thing
