Has anyone ever tried filling up a fill syringe with insulin and using that as backup instead of carrying around a vial of insulin?
I haven’t tried it but it seems to me this would 1) take more space than a vial and 2) Be more likely to lost insulin (stopping being pushed or fill syringe breaking) than a vial. What is it that would make you want to try this?
I like storing insulin in fridge to keep it fresh.
Ditto, What would be it’s advatages?
I’ve used a regular BD syringe, but it seems like the fill syringe would be way too big and that it would be virtually impossible to get an accurate measurement of units. (Are you saying you’d actually think of injecting yourself with it? I’m sure it’s also not all that sharp…)
i think hes talking about prefilling a fill syringe and carrying it around along with a spare pod for backup not injecting yourself with a fill syringe
If you are considering this in order to keep your insulin fresh in the fridge, why don’t you carry a old vial around with just the 200 units in it (which you can use the syringe to fill from a full vial)? Seems like that could be a viable (vial-able?) solution if you want to keep the other 800, 600, or 400 units in the fridge. 
Good pun and good idea!
You can keep a vial out of the refrig up to 28 days according to the drug companies. If you use less than a vial a month, then you might have to just toss it. It’s better to be safe than sorry and possibly wasting more.
Even in the fridge it’s only supposed to last 28 days once it’s opened though.
totally true but I’ve never had a problem using my refrigerated vials for 6 weeks or longer.
True but the pod likes room temp insulin.
I would be concerned that the plastic fill syringe, not being designed for long-term housing of insulin, could result in compromised insulin. The glass vials are designed to hold the insulin, so I would stick with that.
Why would you want to do this? At any rate, I see of potential problems, e.g., insulin leaking from the syringe, accidentally pushing the plunger and losing insulin, the fact that the syringe is not designed to keep insulin in it for long periods of time as Melissa mentioned.
Frankly, I don’t see the advantage. All you would be saving is: 1) the space to carry a vial of insulin, which is pretty small; 2) one step in the pod-replacement process, that of filling the syringe, which takes just a few seconds. I would be concerned about contaminating the insulin by putting it into a non-sterile container with extra exposure to air, insulin leakage from the syringe, bending or breaking the syringe needle, etc. A lot of risk for a slight, if any, gain.
