So, I was diagnosed with late onset Type 1 about 10 months ago and I’m still a bit of a newb about this here so I have a question about Lantus. Sorry if this is flat out dumb.
I’ll start by noting that my endo says that if I have a question about an insulin to pop a new pen and see if that fixes the problem. If it does, throw out the old pen. If not and the problem persists, call him. Awesome.
Also, because people will ask: I keep my unopened pens in a fridge that’s set to 44°F. After they’re opened they sit, when not in use, in another fridge that’s running about the same, sometimes up to 46°, but that’s probably me opening the door more often since that’s also a food fridge. When I have to take a pen out of the house I pack it up with a travel cold pack since it’s summer and it’s regularly 90°F+ here and a motorcycle doesn’t have AC… So generally I’m keeping this stuff pretty well chilled. House runs on a swamp cooler but it’s not getting over 80°F that I know of ever.
A few weeks ago I noticed that my bolus doses didn’t seem to be doing what I thought they should do. I’d spike slightly higher than I expected and then not come down as far as I thought I should. Over the course of a few days this got worse with higher spikes and higher returns. At that point I was adding a 0.5 to 1.5 units of Humalog to get the desired result.
Then on day five of this I went out fly fishing and noticed that when I didn’t eat for about 6 hours my sugars started to tick up (Freestyle Libre 14 day) on my graph. Hrmmm… that night I switched Lantus pens and BAZINGA everything goes back to normal… well, as normal as Type 1 is I guess. Nice. From then on it’s cough smooth sailing.
So here we are 16 days later and I’m on day two of this happening AGAIN. Tonight I’ll try out another pen and see if that fixes it. Based on the fact that I’ve actually seen this before with a flat-out bad pen of Lantus and the previous experience a few weeks back I suspect that will fix the problem so, my question is this:
Has anyone else experienced Lantus going bad early/getting pens that just don’t work? There’s nothing visually wrong with the Lantus but it just doesn’t seem to work. I’ve pretty well eliminated every other possibility including some sort of low-lying infection. Switch pens and the problem disappears. Now it seems with this new pack of pens, they’re going bad early. I find that odd.
It’s also kind of annoying since I take a pretty low dose of the stuff (13u/day) which with a unit to prime the pen works out to about 196, call it 200 units, in two weeks. That means I’m losing 100u per pen.
Could something have gone wrong in shipment? Like the Lantus got too cold/hot during delivery so it’s time until it goes bad is shorter? Am I doing something wrong? Any ideas out there?
Thanks in advance!
