It's your choice Kathy, but the problem with the 10u is it's
not letting you be consistent.
Consistency is having a dose that enables you to shoot lantus twice a day at 12hour intervals, and quite frankly the 10 u is not letting you do that, because she is dropping and then you are having to skip, that is not consistency.
Personally I would go with the 8u that Sandy recommended, with that, hopefully you will be able to get into a routine of shooting twice a day. Are you going to see some high numbers for a while? Well, more than likely, but in all honestly I think that is the
safest and quickest way forward to getting onto an even keel with her dosing.
She doesn't look to be bouncing yet with that 197 at +19 she appears to be flat since the 180, again she is staying considerably low after a skipped shot, all signs that those 10u you shot is way to much for her, the reason that you are getting away with it, is because lantus is a depot insulin not all of the insulin gets to work at once, part of the insulin starts to work straight away and another part remains in crystalline form slowly releasing insulin for a number of days after the insulin shot. The amount of 'slow release' (depot) is directly dependent on the size of the dose the large the dose the larger the depot. The depot takes 6 days to fill the fuller it gets the more the depot will influence her numbers.
The fact that Titi is still in blue since she skipped the shot is suggesting that the depot alone is keeping those numbers quite low, considering that the depot isn't full, it takes 6 consecutive cycles for it to be considered full which you haven't had on those 10u you shot yesterday morning (remember you shot that after another skip which would have drained the depot again), if you shoot the 10u again in the morning I would guess you will see her drop significantly again and will end up having to skip again, this we need to avoid as that will not give you the consistent dosing that you require to get the full benefit of lantus which is lovely flat cycles.
The Most important thing to remember is that the dosing decision is based on
how low the dose can take kitty, not on the pre shot value. Looking at the numbers so far I think, like others that the 10u has potential for taking TiTi far too low, that is why we are urging you to be conservative.
Patience is the name of the game with Lantus.
