Same thing here, however I’m not sure if it’s a problem or not. I can’t really say as I’m so new to it all.
I use Lantus Solostar & Novorapid (I think you guys in the US call it novolog…). Both disposable.
I’ve tried holding the pen in for longer, tried pushing down on the button at the end of the pen a few times after it reaches the bottom/0 clicks.
Always get a little bit on the end of the needle, sometimes get a little bit on the skin after removing.
I do have a theory - and that is this:
When you ‘prime’ the pen to remove any possible air, you point it upwards… because obviously otherwise any air wouldn’t be able to escape.
Anyway, there is always a bit of a dribble on the end of the needle, if you get a “squirt” at all. Also you will notice at the plastic base of the needle there is a little indent.
My guess is that a little bit of the primed solution is getting stuck in that indentation. Then when you inject, the surface tension of the skin is touching that bit. That little bit then gets stuck on the skin, as you remove the needle from yourself, and sometimes it sticks to the needle tip as it comes out of the hole.
Anyone got thoughts? The only way to test would be to not prime it or completely dry the needle (including in the indent) before inserting. I’ve heard that air bubbles aren’t really that much of a big deal unless someone puts a large bubble right into a vein, but I’m not gonna try - bet it wouldn’t feel nice!
That said, I’m sure there is some flex in the system, since the disposable pens seem to be entirely plastic. If you push that button really hard, a little more would come out.
