U40 VS U100

[CORKY]

I've tried to understand the chart available on this forum with no success, I'll be running out of U40 by tomorrow and my shipment won't arrive for a few days, A neighbor gave me some U100 can anyone explain how many lines are equal to 2.5 on the U100 ?. I have only 3 /U40 left, and I'm scared to death to overdose.

Do the U-100 syringes have half unit markings on them? This pictures shows some of the scales used on U-100 syringes.

We can help you with the conversion but a few questions first:

- What is the biggest number that’s on the U-100 syringe? (also a picture of the package or syringe, or the exact wording on it, would be helpful)

- What insulin are you currently using and what dose?

@JL and Chip She's using Prozinc.

Thank you
I am using ProZinc and 2.5 every 12 hours, I only have one syringe left for tonight's dose, hope you can help

I can send it to you via email if necessary

The upload feature is not currently working. You can either copy the picture and paste it in the text box, or drag and drop if using FDMB from a computer.

To read the chart Deborah posted above, look in the first or left most column to find the number of Prozinc units you are giving. Unfortunately, it's half way between the 2.4 and 2.6 units listed, but you can guess the answer is in the middle of the two. Then look to the column to the right, which tells you how many units that would be in a U-100 syringes.

Ok, so this is a 1cc syringe, as I suspected. The numbers printed on it are 10, 20, 30, 40, 50, … up to 100, correct? And there are four hash marks between each number?

If so, then each hash mark represents 2 units (of a u-100 insulin, which Prozinc is not, but I’ll address the conversion later).

Bottom line:
To give 2.4 units* of Prozinc in the u-100 1cc syringes you will be using, draw to the “6” mark (the THIRD hash mark after the zero line).

* 2.4 units rather than 2.5 units for simplicity, so the dose aligns with a hash mark.

It’ll likely be a bit trickier to draw the dose in these syringes, so if in doubt, I’d err on the side of giving a smidgen too little. I’d hang onto your last u-40 syringe too — in a pinch, you could probably re-use it (not ideal, but we do what we have to do).

math: 2.4u (u-40 insulin) x 2.5 = 6 (where to draw to on a u-100 syringe)

Anyone willing to verify my work, please?

Edited to add: in case anyone is interested …to measure 2.5 units, you’d draw to the 6.25 mark on the u-100 syringe, which is virtually impossible to eyeball on 1cc syringes. I used Prozinc for a number of years with u-100 syringes so did the conversions every time I gave a shot.

Thanks to all your support and everyone that has answered my questions and helped me
I do not know what I would've done if I hadn't find this furum, this is expectacular
You have made my nerves at ease in so many ways, thank you
