Welcome, Kim.
Let me make sure I have the facts straight. It looks like Kiwi was diagnosed on 2/21 but you didn't start Lantus until 3/3. (I think I remember reading your story on Health.) You started at a dose of 1.0u but you were giving a shot once a day. You got sick on 3/4 and reduced the dose to 0.5u. You then started shooting 0.5u twice a day on 3/5. This morning, you increased the dose back to 1.0u.
There are a couple of considerations. First, Lantus likes consistency. The more you tinker with the dose or the shot time, the more likely it will be that you get what amounts to weird numbers. In the beginning when using Lantus, it takes approximately 5 - 7 days to establish the insulin depot (or "shed" -- there's a sticky note on this topic). So, at this point, given all of the dose changes, you're pretty much back to square one. What I would suggest is picking a dose and sticking with it. You can start at 0.5, 0.75, or 1.0u. It sounds like you're worried about giving 1.0u. If you want to drop the dose back, that's fine. But, unless Kiwi's numbers drop below 50, it will help if you stick with the dose you choose.
In addition, it is very important that you not only test before you give Kiwi a shot, but that you get spot checks both during the day AND the evening cycles. Many cats experience lower numbers at night. If you don't test, it's very likely that you will miss a dose reduction. In addition, if you don't test at night, you are missing half of your data. At the minimum, it would be help if could get a test before you go to bed every night.
You may want to take a look at all of the starred sticky notes at the top of the Board. They will help you to understand how to best use Lantus as well as how this Board operates so you can get the most out of your experience and give your best help to Kiwi. Below is a description of what's contained in the sticky notes.
- Tight Regulation Protocol: This sticky contains the dosing protocol that we use here. There are also links to the more formal versions -- the Tilly Protocol developed by the counterpart of this group in Germany and the Queensland/Rand protocol developed by Jacqui Rand, DVM and published in one of the top vet journals.
- New to the Group: Everything you wanted to know about this forum and more. Info on our slang, FAQs, links to sites on feline nutrition and to food charts containing carb counts, how to do a curve and the components to look for, important aspects of diabetes such as ketones, DKA, and neuropathy, and most important, info on hypoglycemia.
- Handling Lantus: how to get the maximum use from your insulin and what to not do with it!
- Lantus depot/shed: This is an important concept for understanding how Lantus works.
- Lantus & Levemir: Shooting & Handling Low Numbers: What data you need in order to be able to work toward remission or tight regulation as well as information if you have a low pre-shot number or a drop into low numbers during the cycle.
Please ask questions. There's a huge amount to learn. The people here are very generous with their time and information and we will help in whatever way we can.
