Rookie mistake number 1: Mixed the chamber without attaching the needle first. The result is to compress the air in the chamber –that’s right, pressure.
Rookie mistake number 2: Had the pen on its side while inserting the needle –you guessed it, pressure expels the liquid.

I quickly uprighted the needle preventing a complete disaster. This is where I stopped and REREAD the instructions.

Rookie mistake number 3: I started playing with the gray dial before I was finished with the black dial. Once you start turning the gray dial you can’t reset the black one –or turn back the gray one.

Here is where I stopped and reread the instructions.

Rookie mistake number 4: I did not wait a full 5 seconds during the injection. When pulling out the needle a few drops of liquid still were coming out. I suspect there is not nearly as much pressure behind the plunger as I use when using a syringe. I would recommend waiting as much as 10 seconds before pulling the needle out.

Questions I frequently asked myself:

Can you remove the cartridge? NO
What needles can I use? BD Ultra-Fine Pen Needles.
How many mg is an IU? 12 mg / 36 IU’s = .33 mg per IU
