I've done this many times. Even on a split dose, there is a low level of Levemir still in your system for longer than 12 hours for most people (sometimes up to 24 hours) so you shouldn't be in too much danger. I just take Levemir soon as I realize I forgot the morning dose but reduce the dose by a few units depending on when I remember to take it. For example, if my usual dose is 10 units which lasts about 10-12 hours, I might take 6 units if I remember around noon. The duration is dose-dependent, so a smaller dose will not last as long. It takes 2-3 hours to ramp up to full strength though so you should take a small amount of rapid-acting insulin to cover the gap.Hi guys. I had am interview this morning and clean forgot to do my basal. Im on split dose levemir. Any idea what i do? Leave it til later and continue as normal??
