    Despite the fact insulin bbe date is usually 12 months down the line my insulin appears to only work for a month

    whenever i get a fresh batch from the pharmacy the insulin works perfectly and i store the rest in the fridge. when i come to use the next pen approx 1 month later the pen in the fridge is nowhere near as effective.

    could it the temperature is too cool in the fridge?

    Fridge too warm or too cold? You could buy a cheap thermometer to check your fridge temperature. Put it in the spot in the fridge where you store your insulin, as there's variation in temperature in different parts of the fridge.

    If you do t have a fridge with 4deg temp control. Get a thermometer. I did, and it was an eye opener.

    I used to do storage testing of food and had to insist that I needed cabinets which kept the temperature constant - not domestic fridges. It was some time ago now, but they could be really variable. I used to use polystyrene boxes to try to level things out. You could try an insulated box - polystyrene food packaging taped together should do the trick. Don't forget to make a top for it. Place on a shelf in the middle of the fridge with a thermometer on top - or if you can find a maximum and minimum thermometer set that up - just to see what the range is.
    If it is about right, put your insulin in there. That prevents swings in its temperature as you open the door and reduces any changes when things at room temperature or warmer or colder are put into the fridge.
    If your fridge is not keeping the temperature accurately enough could you arrange for the chemist to store your insulin - if that is convenient for you?

    I got a meat thermometer from Aldis for $2.00, which I keep in my beer fridge to check the temps.

    I keep my insulin on the shelf inside door of the fridge. It has a thermometer beside it and the temperature there averages around 5 degrees, although it can be a little more or a littte less. Never had a problem with any deterioration over the eight weeks or so it is stored there.

    I remember my pharmacist telling me that insulin has a pretty good tolerance to small temperature changes. Bill

    I know that when I get my insulin off the pharmacy driver my insulin is warm as it's been in the van for awhile before I get it but as soon as I get it I put it in the fridge and leave it for awhile before I check it if it is cold again before I place it in the fridge door with the following rest and I can leave it there for a couple of months and it's still okay to use and I have never up to now had a bad batch but I always keep a eye on it so that if any do start to discolour or look funny I get rid of in the bin as if you take it to the pharmacy that is what they will do with it and I order a new batch on emergency prescription and get that same day but that is if I have to but I normally have around 3 boxes of cartridges in the fridge as I do in case they run out of insulin as I have heard once one pharmacy did in the Midlands a few years ago so I now keep some in just for that reason

    They should transport cooled.
