I wanted to bring this up because of my experience trying the short needles with a pen recently.
A couple of weeks ago, there was a discussion on short pen needles (4mm) versus longer pen needles. I think the recommendations for shorter needles are very much “safety” based. I never thought the shorter needles worked as well, but I believe that because they remove the risk of “inadvertent” intramuscular injection (IM), they are the recommendation now. (their quote - “Absorption rates differ greatly depending on how active the muscle is (insulin is absorbed more rapidly in very active muscles), making muscle injection more unpredictable, potentially leading to dangerous lows.” )
And also because of things like “patient compliance” - the shorter ones are “less scary”, so people are more likely to take their insulin when they are supposed to.
But I wanted to give them a fair shake, so I went back to them and tried them again…
Here is what I saw:
The worst BG’s I can remember. I didn’t recognize the disease. I could see things like they were posts on another site - people talking about how their BG spikes after eating, how their insulin doesn’t seem to work, how long it takes their insulin to come in, what am I doing wrong, etc, etc…
It was incredibly eye-opening. I really seemed like I had a different disease. I had to stop. I was so happy to go back to the 8mm needles.
For small injections they did not seem to make much difference. For example, a 1/2 unit injection was no big deal, I didn’t notice a difference.
But when I did larger amounts, like for meals, I spiked like crazy.
It’s possible I am getting a bit of IM with the 8mm needles. But whatever the reason, I will never go back to those 4mm’s.
I have used both enough - in all kinds of real-life scenarios, not the confines of a lab. I have used them for different amounts, different meals, running, sitting, correcting small highs, correcting big highs, breakfast, lunch, dinner, snacks. Those are things that don’t happen in a lab. In one of the experiments I saw referenced, they actually only did a total of 56 injections with 28 people. That’s ridiculous.
I want to go to every T1 who has ever complained about post-meal spikes, give them a hug, and give them a box of 8mm’s and say, “Try these.”
