My daughter, much like many other newly-diagnosed PWD, started out with MDI (with Lantus and Humalog, specifically). Waiting from the time of pre-bolusing until the onset of action before beginning to eat is a significant challenge for growing children who want to eat RIGHT NOW once they become hungry. I had heard that for some people, Novolog began working faster. So we tried Novolog, but no difference in onset of action/time until peak action was noted, so we moved on to Apidra. This insulin provides my daughter with a faster onset of action/time until peak action and shorter duration of action. Which shortens the time she has to wait until beginning to eat. Which makes her happier, which in turn makes me happier. I have read that Apidra does have a tendency to “crystallize” much more readily than the other rapid-acting insulin analogs, however. For some reason unclear to me (as I did not research this issue because my daughter does not use a t-Slim pump), this undesirable quality of Apidra causes much more of a problem with the t-Slim pump than it does with other tubed pumps, to the extent that I currently know of no one using Apidra in their t-Slim pump.
