9/18 Chloe - AMPS 92 | PMPS 98 - nearly empty pen question

Yesterday: https://www.felinediabetes.com/FDMB/threads/9-17-chloe-amps-92-pmps-72.253078/

Dose reduction today!

We are nearly at the end of our first Lantus pen, and there was a little resistance to me pulling just .25U this morning. Like, my syringe’s plunger kept being pulled back toward the pen. Is this common as you get to the end of a pen or was this just a sticky syringe?

 

I have never used a pen, so I might be misunderstanding your question, but I had 1 or 2 syringes that were "really sticky". I knew the problem was the syringe and not the vial, because although the vial of lantus I use can go in a pen, it does not (So I draw directly from the vial and can see how much liquid is in it.

Hope this answer will bump up to other pen user's eyes....

 

Thanks for the bump!

I move the plunger a few times before I draw insulin just to lubricate the syringe a bit. Normally I pull back to where I need it and it stays. This morning, I pulled back to .25 and the plunger kept going down to the 0 line.

The pen also has a plunger in it that works by negative pressure. The plunger moves toward the end of the pen as you draw more insulin so there are no air pockets. Since I am very close to the end of the pen, I wondered if the negative pressure was messing with the syringe.

 

Just want to say that your foot chart looks amazing!

 

Glad it’s useful to you!

 

Yes. You have negative pressure inside that pen pulling your syringe plunger back. I know the pens work on negative pressure, but that is weird!
