Hi Lori,
The ProZinc package insert simply states to gently roll the vial. I think they should’ve coughed up the bucks for the extra ink to explain it better!
I roll the vile gently in a horizontal position about 10 times, then I gently invert the bottle back and forth (tilt it upside-down, then right-side-up...like a rocking boat) about 10 more times. Then I gently roll it a couple more times, then I draw the insulin
immediately into the syringe. If you walk away from your mixed vile,
even for a minute, you should re-mix it before drawing your dose.
The problem with mixing cloudy insulin is...if it's not mixed completely when you draw just one dose...you've now changed the concentration of the rest of the vile. If the vile is consistently mixed poorly...the remainder of the vile could be considerably weaker, or stronger, than intended.
Cloudy insulin, that isn't consistently mixed well...is like a box of chocolates...you never know what you're gonna get! :lol:
Here's a link to the ProZinc website. Scroll down to the "How to fill the syringe" section, and click on the link to the video. In my opinion, this chick is rolling her vile too vigorously, and not long enough. She's also only rolling the vile while completely up-side-down...how the heck does that mix-in the "heavy" particles that settle at the bottom of the vile? I think gentle patience is required if you want your insulin to remain at the proper concentration. Maybe the ProZinc "video chick" is late for work?

I also found the following link, which explains it best. It's pretty much what I tried to describe to begin with...only better!

I hope this helps.
