A very quick and brief question! Apologies for not using this forum in a while, but Sica is now 15 and doing amazingly except for a small bump in the road recently.

Our doctor recommended changing her dosage from 1 unit to 1.5 as her numbers have been quite high. We have a Lantus Solostar pen and he gave us a 1 ml syringe.

How am I supposed to adapt the values for this? How many mls should I use to make sure it is 1.5 units?

I added the 911 because her numbers are pretty high rn and it's crucial that we administer the dose ASAP.

First of all you need to give us permission to see your spreadsheet. Please do this and remove the 911 and change it to a question mark.
 
From the sticky on syringe info:


  • U-100 3/10cc syringes with half unit markings are the best to use for drawing Lantus, Levemir, or the Biosimilars from vials, cartridges, and pens.
  • BD Ultra-Fine, CarePoint Vet, Monoject, GNP, UltiCare Vet Rx, Sure Comfort, and ReliOn are just some of the brands available with half unit markings.
  • Syringes come in 5/64 inch (6mm), ½ inch (8mm) or 5/16 inch (12.7mm) needle lengths. Needle gauges are 29, 30 or 31 (31 being the thinnest)
  • Full and half-unit syringe scales:

Sorry, I'm not sure how to edit out the 911. And the spreadsheet is irrelevant as I hadn't used it in 2 and a half years. I just need the conversion from units to ml

If the insulin is U100 that means there are 100 units in one ml. Are you sure it was a one ml syringe that you were given, and not a U100 syringe?
 
Well I’m new to this but to me it seems you’re in a difficult situation bc even a tenth of one ml (if that’s how your syringe is marked) would be 10 units of insulin. How difficult is it to ask your vet what to do? If it were me I might consider at least giving one unit with the pen (if I couldn’t get ahold of my vet) but your vet based on her numbers may give different advice.

edit: then I’d also call local pharmacies to find some u100 syringes

Thanks!! We ended up deciding to try 2 units again, so we'll be using the pen
 
Doubling the dose is risky. You should be able to get the correct syringes at any pharmacy although you might need an RX from your vet. Not having any information as to his readings I can’t say for sure but the most a cat gets an increase here is .25. If you decide to doubt is the dose please check the bg often.
