Hi Diana! You have certainly come to the right place to find out that it's not just you! I am the mom of a 17 year old who was diagnosed at the age of 21 months. I am not a medical professional, just someone who shares my diabetes experiences with others in order to provide helpful information.
My daughter was taking Lantus a few years ago to prepare her body for the insulin pump. There were adjustments that were made while she was on it, such as changing the dose from PM to AM which seemed to make a positive difference in her bg's. I do not believe that we experienced any specific issues with stability or delivery at that time though.
Have you searched this website for previous postings? There are many of them regarding the use of Lantus that you may find helpful. Check them out and also check for others responses to your post. I would most definitely speak to your endocrinologist after doing some research and I am certain that between the two of you can come up with a regime that works well for you.
Best of luck!
I use Lantus cartridges in a Humalog pen. And it works perfectly. For me, a major benefit of switching from NPH to Lantus has been the reduced variability in action. And delivery via the Humalog pen appears to be very consistent.
