Purgated injector

Hello everyone, I am DM1 Lada and I am injecting Tresiba (16u) and Humalog (3/4/3), I am in the stabilization phase of my glycemia, it is not being easy.The purging of the injector of both insulins I always do when the injector releases, but not in the subsequent punctures.In Humalog's instructions he indicates that every time, before each injection, purge with 2 units ,,,, is a tremendous waste of insulin and the truth I do not know if it is always worth doing to make sure that the injector works well.Do you always purge before each injection of insulin Humalog?Thank you so much

Yes, you always have to purge. You are right that it is a waste but you make sure that the dose you are injected is correct

Yes, 2 units for Novorapid and 3 units for Toujeo, vertically so that there are no air bubbles.
The manufacturer puts it in the prospect.

Look at the amount of insulin that remains in the pen when it ends, another waste.

I do not see it waste if we do not do it that insulin may not between good.You have to always do it.

Thank you very much, I will do so from now on with the Humalog !!With the Tresiba do you also recommend purging before each puncture?If I remember correctly, the prospect only speaks of purging the first time for that insulin ,,.

With all insulins you have to do it.
