I'm learning about the pump (Animas Ping) before I go for "training" to start using it next week, and the DVD said to only put room temperature insulin in the cartridge... But you're supposed to toss room-temperature insulin after 30 days, and I'm quite positive that I'll never use up the entire vial in that amount of time. (The pens have been really nice for that, since they have less in them and I use one up well before that limit.)
I emailed my CDE to double check on these points, and she said:
1. It should be room temperature before going in the cartridge. Cold insulin is more likely to cause bubbles.
2. Though I can put the vial back in the refrigerator if I want, it'll still need to be thrown out after 30 days.
That just seems wasteful. I'll follow her directions unless my endo tells me to do anything differently, but I'm curious: Do any of you pumpers handle it differently? One thought that crossed my mind was that maybe a person could fill the cartidge with cold insulin, let it warm up, then push any bubbles out before inserting it into the pump.
I dunno. I'd just hate to see so much insulin go to waste if it doesn't have to.
