Yes, that's correct. Toujeo has it's own pen, with its own markings, as I understand it, and one unit delivers the same amount of insulin as one unit of Lantus, just dissolved/diluted in less liquid.Toujeo is 3x stronger than lantus.I can't get my head around the fact that this means I take the dose as marked on the pen by my nurse and it just means I will take the same dose as Lantus just not as much in volume. Is this correct?
