Pen Needles - BD Micro-fine 4mm - blocked

[mum2westiesGill]

I'm at the end of the box now but I've had two instances (one a couple of weeks ago and another last night) where I've done an air shot and....no insulin came out! Did a second air shot and the dial on the pen would not move. I then put a new needle on my pen, did the air shot and insulin came out.

Any comments welcomed.

Mine are 5mm and I've only ever had one dud in the last 18 months.

We've had a report of this in the past here:

Don't know what type of needle it was though, but it does show the value of airshots that were discussed recently 🙂

I wrote a poem, suggesting that it was a lonely lancet that had sneaked into the needle box:

I was doing my BI with the faulty needle last night. Imagine the levels I'd have got today if I hadn't done the air shot!

Did you check the inside part of the needle? Could it have bent at a 90 degree angle and therefore not penetrate the end of the cartridge? Just a though. Or could there have been an air bubble in the cartridge? Which is exactly WHY we were told to always do an airshot?
