I am type 2 but on MDI using Lantus SoloStar pens and Humalog Kwikpen JR pens. I put this in type 1 and LADA because you people are probably most experienced with insulin.
I never let my pens get hot. I live in south central Texas and we get hot here. I am beginning to notice a trend, where my BG doesn’t respond as fast or well when bolusing Humalog when the pen has been opened for 25+ days.
At first I thought it was because of higher insulin resistance, but I am pretty sure now that the Humalog is not as effective as it ages. I know some use insulin well beyond the 28 day window, so do you think I am right, and should slightly increase the bolus dose as I near 28 days? Thanks.
