Hi Grant
Looks like Nigel has been keeping you a bit busy. I popped in because another member asked me to do so as she was concerned about the number of skipped shots, etc.
I’ve read through all the condos you’ve posted including the introductory one as well as the one on the Main Health forum and studied his SS. I’m glad you are using the Prime now; it’s better to try and stick with one device for recording on the SS as Linda suggested. The Prime does have a history of reading lower than other meters so that might explain the large gap between it and the Libre although we don’t have a lot of info on the Libre, other than what has been posted in your threads, to know about its consistency. But sticking with one device and following trends is the best way to go.
The issue that concerns me is that information has been provided to you with no guidance as to how it fits in with SLGS which is what you stated you wanted to follow. I’d also like to point out that if you are following SLGS and you get a number lower than 90 on a human meter, you need to reduce the dose; more on that later.
It does appear the starting dose might have been a bit high for him and he actually even “earned” a dose reduction from 1u to 0.75u in the a.m. cycle of 1/30 with a 63. I’m not sure the basis for the 0.5u being suggested but it’s done and he’s hanging in there pretty well.
In regard to the AMBG of 118 on 1/31, SLGS does state that, starting out, if the PS is below 150, to not give insulin, but also remember these are guidelines, you had some data and had shot a lower number with the 0.5u dose even the night before, and the number wasn’t that far below 150 (it was basically within 20% meter variance range). Taking all that into consideration, it would have been fine to shoot the 118 and leave some HC food out when you had to leave but skipping was also fine if your comfort level was zero.
However, it should have been explained to you that because Lantus is a depot insulin, when you skip a dose or shoot a reduced dose, you are likely to see the same kind of cycle, at least for the first half of it, as you would if you had shot. Also, because the depot from a higher dose can affect the BG for up to six cycles, he likely had some depot from the 1u that day; in other words, it’s unlikely that shooting would have resulted in any difference in numbers with the exception that his PMPS likely wouldn’t have been so high. In summary, either way would have been fine but next time when faced with a number that is near or not too far below 150, you can perhaps take all that into consideration.
He earned another dose reduction the night of 1/31 when he dropped below 90. Since you had been shooting 0.5u, than according to SLGS, the next dose would be 0.25u. You were right to skip the dose on 2/1 a.m. cycle with an AMBG of 74 because below 90 with SLGS, we strongly discourage shooting. A 74 also would normally call for another reduction but with the L insulins, we often avoid taking back-to-back reductions because it’s often the depot talking; however, he’s had a lot of skipped shots, including last night, so his 0.5u depot probably really isn’t a “normal” 0.5u depot by this morning.
He dropped to 82 today which would normally constitute another dose reduction and that plus of three back-to-back skipped shots, IMHO, it would be a smart thing to take the reduction to 0.1u as you’ve probably drained the depot quite a bit by now.
It will be interesting to see what he does tonight; a +10 test would be good and if you are home to test tonight and if he’s above 90 at PMPS, I’d suggest you shoot 0.1u.
Is it possible he is a diabetic that can be diet controlled? Sure and we’ll keep our paws crossed for that. And even though I have seen cats go from 0.5u to no insulin, it’s not often that they do and stay permanently in remission. The numbers will guide us and it’s possible we will find as the depot really drains that he “might” need a little more support. Time will tell.
For all readers and the advice givers in this condo and the last one: I want to be sure and address the notion that if a shot is skipped, the cat cannot hypo. This is not correct. Depending on the depot, the insulin can continue to drop numbers quite low even with skipped shots so it’s important to be vigilant even when a shot is skipped or a reduced dose shot. As long as the kitty is past their normal onset and is either going up or is super flat, the chance for a hypo diminishes but I’ve seen cats who’ve had shots skipped drop into the 30s, no symptoms even though that number is definitely low enough to potentially see symptoms.
