When I was about to take an immitrex shot, I drop the injector pen and it hit the bathroom floor and the needle popped out. I noticed a little bit of the medicine came out but I think the majoritty of it is still there. I ejected the vial back into the container, reset the pen and used the other vial.

My question is this....is there anyway to extract the vial to see how much of the shot is left?

I copied this from the link to the left...Imitrex tip for dividing dosages, but it applies to the question you have asked about checking the vials contents too.

   Here's what I do...

1) I load the bottom part of the injector pin (the part that has the syringe in it) just like I'm going auto-inject myself as normal.

2) Once it's out of the case, I unscrew the syringe part of the pin so that it is again in two pieces. This exposes the top rim of the syringe (barely sticking out of the bottom half).

3) I use my fingernail to pull the syringe out of it's holder. I now have the syringe all by itself in my hand.

4) I remove the label from the syringe (or peel it back) so I can see the amount of solution is in the syringe.
