When to switch to new pen/vial - good to the last drop?

[Sugar’s Mama]

Hello!

We have made our way mostly through our first pen and have the next one ready. We have about 20 units left and it looks clear and we are still seeing Sugar’s numbers go down after his dose. There is an air bubble that has built up over time. Is the last bit any less potent? Should I switch to the new one or use the existing one until it’s empty? If it’s suggested to switch, would you keep the almost-empty one as a back-up?

Thanks in advance for any guidance!

I can only speak from experience, we used every last bit we could when we used up a pen.

it was apparent from the BG tests on Hendrick that the insulin was still just as effective

I agree, use every drop. One thing I do to get rid of the bubble is to turn the pen where the bubble is near the cap and use a syringe to pull out the bubble. Then I toss the syringe.

Ok, great! Thank for chiming in.

Will try that! It’s getting close to where we draw from, so that could make the last draws easier.

wish I would have thought of that, that's genius

we fought the bubble monster valiantly and it was such a struggle as we got down to the last drops

I am seconding, thirding all the suggestions above. Landos lantus pens lasted 6 months. There was still insulin in the pens when i switched to a new pen ( his numbers were the same during the switch FWIW)

Thanks @Lando demando - helpful to not ditch the precious insulin early!
