Good morning everyone,
hope everyone is having a good day!

I have a question on the conversion chart if anyone can help
I see that 1 unit on the u40 is 2.5 on the u100

Does that mean if I start shakespeare on 1 unit of PZI
that it is like he is getting 2.5 units of Lantus??
or do the insulins have different strenghts and the chart is only for the usage of needles

I am not sure if I am making sense right now but if anyone understands i would love some help

if not I will try to explain it in another way

thanks!
 
I hope this explains it- certainly better than I can.

A vial of insulin is a combination of insulin hormone and a sterile liquid, called the diluent. The concentration of the insulin to the diluent determines its strength.

Though U-100 insulin is the most common, insulin may be ordered in a variety of strengths, such as U-40. The "U" value of insulin indicates its strength - the number reflects the number of active insulin units in each mL of liquid. You could think of 100 "units" as 100 tiny pieces of insulin floating in each mL of diluent.

U-100 will have 100 units per mL, and U-40 has 40 units per mL. This means that U-100 has 2.5 times the amount of active insulin per mL, therefore 2.5 times as strong.

Appropriate syringes are made for use with the respective insulin, marked with the correct measure for dosage. We strongly recommend that you use matching insulin and syringes.

However, it is possible to use the below conversion chart to convert from U-40 to U-100 or U-100 to U-40 effortlessly. Simply find the amount that you need to use and find the appropriate conversion in the adjacent column.

Before deciding to use non-matching equipment, make sure you understand the concepts of dilution and units per volume - it is very important for understanding the actual amount of insulin your cat receives. When talking to your vet, make sure you're telling him the actual amount insulin you're giving. As an example, let us say you use U-40 insulin in a U-100 syringe and administer shots at the 10 unit mark. Don't get confused and tell your vet you're dosing at 10 units - because of the dilution, you're really only giving 4 units of insulin.
 
Prozinc is a U 40 insulin......Lantus and Levemir are U 100 insulins. The conversion chart is only for use when using a U 40 insulin in a U 100 syringe.
 
wow Sue, you are good!!!
thank you so much for the explanation...

jsut to make sure I understand

THe PZI insulin is not as strong as the Lantus
I have the u40 syringe so I will use those for the PZI
If I start Shakes at one unit of the PZI with the u40 syringe
It is almost like giving him .4 units of the lantus on the u100

IS that right?

and THANK YOU!!
 
One unit of PZI with U40 syringes = one unit of PZ
2.5 on the U100 syringes of PZI = one unit of PZI

It will be easy to give one unit or any combo of .5 (like 2.5) on the U40 syringes - what you see is what you get. If you need to start dosing by .25 units (like 2.25), you change to the U100 syringes and use the conversion chart. (If you haven't already, copy it off and keep it handy.)

If it doesn't make sense, just keep asking questions. You want to have this clear in your mind. It is tricky.

PS I am not good. Someone else much smarter than me wrote that. I just know how to search and copy. :mrgreen:
 
yes, each 'unit' on the u100 syringe is the equvilent of .4 unit of pzi on the u40 syringe. soooooo, if you want to give let's say .6u you would give 1.5 units in your u100 syringe.
 
thanks for your help
I think I have it, I am so nervous about him going hypo
so I am starting at 1 unit tonight...
whats another sleepless night!

thanks and will try to post tonight while I am watching him
