The two are made by different methods and the period they are effective is considerably different.

The Novorapid is a "synthetic" insulin and the Actraphane is a lab grown (to keep the actual process understandable) actual human insulin.

Novorapid is a "fast acting insulin" that starts working even faster then real human insulin and would be used before eating with limited to no effect on sugar levels barely a couple of hours later

The Actraphane is a "mixed" insulin where part of it is "fast acting" to help with a meal and another part is a "slow acting" (uptake) which will have a (lingering) effect for many hours after injection.

If you were looking for a longer acting insulin for your daughter, Novorapid was not the correct product. The Actraphane provides both near immediate and long acting insulin replacement.

Has the Doc suggested using on of those insulin "pods" - it's getting more popular with kids.

It's literally this pod that you stick on the lower belly (similar to CGM sensors). You fill it with the prescribed insulin, stick it on and it kinda "leaks out" the insulin as some rate to provide a constant supply over the course of 2 or 3 days (depending on how it's set up to dispense).

Perhaps worth a discussion with the Doc.

But generally the "mixed" (called mixed analog insulin) is given like you would the fast acting ones "pre meal" at 15 or 30 minutes (or whatever the prescribed interval is) and "some" of the dose works on the meal. The second part continues to work for the next few hours.

They are premixed typically in a 30% fast/70% slow/intermediate working insulin which negates the need to inject two different acting insulins at different times to gain the total effect.

We have been on Novarapid since my 10year old was diagnosed in 2019. I'm not so sure how to use Actraphane. We've been prescribed with Actraphane, novarapid and tresiba. I'm so confused.
