Individuals with type 1 diabetes type 2 diabetes and juvenile diabetes may be able to use insulin glargine. Also, children over six years of age can use it.
It is very important to remember that insulin glargine looks different as compared to other longer acting insulins because it is clear in appearance, as opposed to cloudy like all other longer acting insulins. Therefore, this should be kept in mind for those using both short and longer acting insulins, to avoid confusion. In patients with type 2 diabetes mellitus, insulin glargine significantly improved glycemic control compared with once-daily NPH insulin, but not when it was compared with combined treatment with once- or twice-daily NPH insulin.
