Hi All!
Trusting you are doing well. I'm currently using Apidra disposable pens and using it at meal times. Sometimes, when I'm injecting it, some blood seems to push up back into the carteridge. This usually happens when the pen is still relatively new and then means I have to discard the pen and start using a new one. I use microfine 8mm needles with it. I also use Lantus before bed time with the same type of needle and have had no problems with it. Out of the 10 pens I've used since I was diagnosed with diabetes, I had to dispose 4 due to this happening.

Has this maybe happened to anybody else?

Keep well and stay safe!

To me that would mean you are hitting a vein, but what I find odd is that it only happens with the Apidra pens. Do you inject the Apidra in a different area on the body than the Lantus? Or do you use the same locations and mix it up.

I tend to use the apidra on the abdominal areas since it's the easiest before a meal. The lantus I use on my thigh so I suppose that might be the cause (hitting a vein). I'll try the apidra on my thighs as well since it's never happened with the Lantus and see how it goes. Just a bit of a shlep before a meal but I suppose that's part of the game! Hiehie!

Hey. I'm not sure if this is correct, and it probably is very wrong but i'm a dental student and when we have to inject our patients with anaesthetic, the syringes we use self aspirate. This means that if you do hit a vien, before you inject some blood will come back in through the needle to show you that you are in a vessel. It seems a long shot but it's all I can really think of.

I use the same needles you do with cartridges as opposed to disposables, and i've hit blood vessels plenty of times but blood has never come back into the cartridge. I'm assuming it is your pen...

Hope that helps... :s
