I'm currently in a honeymoon period of type 1. Therefore I'm taking very small doses of both basal and bolus insulin. Usually I am only injecting 3 units of novolog with each meal (20:1 carb ratio) Looking at the design of this pen-- it seems obvious to me that the first and last unit of a dose of any size are fairly imprecise. Mid dose-units should be fairly accurate-- but if you are only taking 3 units at a time, and the first and last unit are prone to being iprecise, your doses could be pretty inconsistent, particularly with small doses. Have any of you had this experience / concern? Are syringes better in this regard? Any suggestions?
I had a lot of trouble with Pens and my CDE recommended I try a pen with half unit dosing like the Novolog Jr. I initially took 4u Lantus and 1-5u novolog with meals my I:C ratio was 1:20. Ultimately, I found it nearly impossible to get the dosing just right and often found myself high or low. I switched to a pump and am very glad I did.
For my 3 years old daughter I use half unit pens: novolog junior (for novolog and levemir) and luxura hd (for humalog and lantus): i find their dosing accurate enough.
But if you need super precision and don't want/need a micro pump look at this (I think) wonderful pen: Pendiq (link). It costs 170 euro plus shipping (online shop).
It can work with humalog/lantus, doses 0,1U from 0,5U up, it's electonic controlled and "remembers" all data you can download later to PC.
Here a video:
169 Euro is about $223 US, just to let you all know. I'm not sure if this is available in the states.
To exactly deliver one unit with a pen is problematic but 2 or 3 units should work perfectly - at least with a NovoPen. I really recommend the NovoPen Echo with 1/2 unit delivery and memory (very important for the basal).
I'm trying to get my hands on an Echo for mealtime insulin. No one has even heard of it around here, not even the diabetes center.
I have an Echo .It keeps track of amount used and time of injection.Also measures in half units but only up to 35 units. It is made by Nova.
Yep, not available in the states. I would highly recommend Humolog luxura hd pen, although my insurance (United Health Care) does not cover it.
I use Apidra in a pen. For most meals I only inject only 1 or 2 units and as far as I know the dosing has been accurate. Generally, no unexpected highs or lows. I would love the flexibility of 1/2 units, but I've gotten so used to Apidra, I don't know that I want to switch to Novolog. Of course, I might have to if the Apidra pen shortage isn't resolved soon.
It isn't approved, but it works: you can put an apidra cartridge into a Luxura HD pen. Luxura is for humalog, but it has the same size as apidra. Apidra is only a little "longer" so you have to put on an open needle while closing your pen the first time just to let some insulin spring out.
So you have half units with apidra.
Does this work with Novolog too?
No, but novolog has his own pens with half units, they are novopen junior, echo and there should be novopen demi too with half units.
The same luxura hd works with lantus.
