Definitely ask for an updated Rx if you’re running out with your current “30 day” supply. Being in a pump it’s fairly simple to document your need for more than you’re getting - it’s not like MDI where they pretty much just take your word for it. You want your RX to be for more than you’re using in your pump just due to waste - the amount of insulin “lost” to tubing, priming, etc. Based on my insulin usage I would only “need” 2 vials, but I get 3 due to the amount that is tossed with each site change - I would run out of I only got 2.
Like others I tend to have a stockpile… I feel more secure having 2-3 months of insulin on hand at any given time. I even have insulin I know I will not be using (ahem, Levemir) but I find it hard to throw it out… even though I have an entire box of Lantus pens sitting right next to it for use as my pump backup if needed.
I haven’t used up my 2 “sample” vials of Apidra (actually just opened up the 2nd bottle a few days ago) but I’ve already filled my Rx (last week, actually) just to get a little bit ahead on my supply.
