? U40 to 1 ml U100 conversion

[Ivana R]

Hi all,

Due to the covid virus I still have not received my syringes and am almost completely out. I use U 40 1/2 ml normally but have a lot of U100 1 ml.

I read that U100 1/2 ml and U100 1 ml are different conversions from the U40 so any help would be appreciated!

U100 syringes are U100 syringes. BUT it is more difficult to measure those small doses in the U100 1 ml syringes. The syringe barrel is the same length, but it holds 100 units, so the lines are closer together.

The U100 1/2 Unit syringes hold 50 units of insulin, so the lines are closer together, but not as bad as with the U100 1ml syringes. If you have any U100 3/10 cc (ml) volume syringes, those are better for measuring the smaller doses our diabetic cats get.

Conversion from U40 syringe to U100 syringe is multiplying the U40 dose by 2.5.

I was using the U100 1ml syringes with Wink at first, because he was a foster cat and that is all the shelter had given me. He was on a U100 insulin at the time, so it was extremely difficult to measure the doses with those larger volume syringes. Extremely difficult. Easy to overdose.

Hope you are home testing because you will want to be doing that for the syringe change.

p.s. Getting all the air bubbles out of the syringe will be very important. Finger flicks.

Hi Deb,

thanks for your response. i am definitely home testing but unfortunately only have the 1ml u100 syringes to make due for the time being. he usually get 2 units with u40 which i'm seeing is 5 units on u100, but i will give him a little under as to not overdose


thanks for your help
