A few weeks ago, I discovered that I had been throwing away insulin. If you know me, that’s not something I would ever knowingly do. That’s not something anyone would do, especially with the high cost of insulin. But here’s what happened:
My Tresiba insulin pen said it had 0 units left in it; however, I decided to check if there was anything still left that I couldn’t see. At a certain point, the “piston” of the pen gets to its furthest point and cannot inject insulin anymore. It looks like this:
It was at this point that I pulled the insulin out of the pen with a syringe.
*Here’s how I did it:
I inserted the syringe into the pen tip, careful not to hit any pieces of the inside of the pen as the “piston” is quite close to the end, pulled the insulin out (I didn’t inject air), and that’s it. It’s important to use the same volume syringe as the insulin pen (ex: U-100).
It was really easy. And guess what? I extracted about 14 units of insulin! That’s way too much insulin to be throwing away each time.
What is your experience with extracting insulin from a pen?
