Nadir at 3 hours - Lantus Glucose Curves

[amandazzle]

Foster moved onto Lantus about two weeks ago. I have been trying to keep him on 1u twice a day, but when I do test, his numbers are anything but consistent.

Today I was home and able to take a pretty proper curve. However, it appears that his nadir hits at 3-4 hours and then comes back up pretty quickly after that.

I would consider a higher dose, but he has hit as low as 40 and that makes me nervous. I did feed him some snacks when he hit his low today. It is possible that may have counteracted the insulin.

As I work, I don't think I can manage a more frequent injection. I commute to work and live alone, so I am gone about 10 hours on average every day.

I would like to inject him early, but that will throw off my working schedule when I am not on vacation.

Any suggestions?

Thanks,
Amanda

Yo may be seeing rebound *going too low and body compensates. I would try with 1/2 unit twice daily.
Did Faster eat normally this morning?

Interesting. I was thinking about dropping it as it hits so low, but the 3/10 syringes still make it hard to aim for 0.5 units. Not sure if I could dose that very correctly.

Magnifiers!
Carson Clip and Flip fasten to existing glasses.
Visor types work if you don't wear glasses.
Hand held and stand magnifiers may be helpful too.

What kind of syringes are you using? You can get ones with 1/2 unit markings

I agree this dose is too high for him- whenever a cat drops under 50 you should reduce the dose. However bear in mind because he did drop too low yesterday that he will now bounce for 2-3 days so ignore the high numbers and continue to only give 0.5 units - the bounce will clear and then you will see how the 0.5 units works!

Bounces - what are they and is my cat doing them?
When a cat isnt regulated, the blood glucose has probably been high for a while. As the insulin starts to take effect and numbers start to come down, the liver has to learn to adjust to the lower numbers. We call this "liver training school". But before it relearns that low numbers are ok, when the BG drops to a number lower than the liver is accustomed, or if BGs drop low, or if the BG drops suddenly, the liver”panics” and reacts by releasing counterregulatory hormones and glucagon. This drives the BG back up. This is what we call a "bounce". Bounces can take up to 72 hours to clear so we are generally careful about increasing doses during the bounce. Once the bounce clears, then you can see the "real" numbers and determine if the dose needs to go up or down.
