I finally started home testing. Her numbers are crazy...300's to mid 400's (right before her morning shot) which leads me to believe that her lantus (2 units, twice a day) is not working. What do I do now?
If you have been using insulin 3 - 5 days, then what you need to do now is run a curve - pick a day when you'll have 12 hours straight to do testing.
Begin with the AM pre-shot test which lets you know if it is safe to give insulin (since you are new, never give it under 200; later, you may lower the pre-shot number when your data indicates it should be safe)
Now, every 2 hours from when you give the insulin, test and record the levels
Finally,
using the guidelines for tight regulation (posted in the Lantus forum - good to print out for reference), compare your lowest test value
on the curve with the criteria for dose adjustment. And after reading the Lantus stickies, consider posting in the Lantus forum, as they have a great deal of experience in using and adjusting doses of Lantus.
Note that if you are feeding dry food, or high carb wet food, it will not be surprising if the numbers are all somewhat high. At that point, you'll have a decision to make about what you want to do - reduce carbs in food OR increase insulin dose. We encourage the former, as it may assist with becoming diet-controlled.
On the other hand, if the dose is actually too high, you might see a very unexpected low at some point (on the curve, or at a pre-test), followed by high test values which occur due to the liver compensating for the low through a number of biochemical processes. This requires a dose reduction.
If you have already lowered the carb levels, you could be looking at a dose increase. At the current dose of 2 units every 12 hours, an increase should be small - 0.25 units - which you will have to estimate on your syringes. Using syringes with half unit marks will make this less difficult, and using a magnifier of some sort definitely helps those of us who are visually challenged (like me!)
Dose changes should be held stable for 3-5 days (6 - 10 cycles) unless there is an immediate need to change (ex. very low pre-shot, too low nadir/low point, or very high urine ketones/ketoacidosis), before running another curve to see how the new dose is working.
This process of dose adjustment is careful and keeps your cat safe.
