That’s not at all how it works. Its duration is dose-dependent. All insulin though, even Regular insulin and rapid-acting insulins will last longer at higher doses. If 6 units kept me flat overnight but didn’t last long enough, I wouldn’t split it into 3 and 3. I’d take 6 and probably take another 6 or whatever I needed in the morning as well. It doesn’t have to be an even split, the beauty of Levemir is you can take more during the day and less at night or vice-versa to meet your basal needs. The UK NHS recommendations are for Levemir to be taken twice/day. I can tell you through personal experience that one dose will not last past 15-16 hours for me, unless I took enough of it that I would be extremely hypo all day and night. I’m not sure what your opposition to this is, it is well-established that Levemir’s duration is dose-dependent and that splitting it makes sense for most type 1s.
