I am most interested in the preparation of the pen before giving the shot to my husband. I know that I have to shake the pen to make sure the solution is thoroghly mixed. After the needle is attached, I have been flicking the vial to make sure all air bubbles go to the top and then I release 2 units into the air. Now I click the dosage units to the prescribed amount and inject the insulin. It is the 2 pre-injection units that I am questioning. This reduces the amount of insulin available to meet the 90-day supply. Should I be releasing 2 units before each shot? Or is that only for the initial shot given at the first use of each pen? Or should I be releasing only 1 unit to get rid of any air bubbles?
Here's a video link for you.

I use an insulin pen too. Doing the 2 unit shot not only gets rid of bubbles but it also ensures there's insulin in the needle so that when you're ready to inject, air doesn't take the place of insulin therefore you get the right dosage amount.
Your doctor should factor in the 2 unit shot when writing the amount of insulin prescribed so that s/he prescribes you enough to get you through 90 days. (Your pharmacist can probably help you figure it out too so when you next go to your doc you can bring in the calculations.)
