I am on large amounts of Novorapid and Lantus Solostar Insulins. I therefore have to take many pre-filled pens with me when I go on holiday. Fridges aren't always available, and even if they are, I still have to transport the Insulin. A Frio Pack only officially holds 5 pens (although can get 7 in), but Frio packs, after a while take ages to get to working stage, and have to be replaced at a not particularly cheap cost. I have also tried using a small insulated bag with a frozen pack in it, but am not sure if this is good for the Insulin, and this will only last a certain amount of time, and no use if no freezer available ! I always take twice the amount of Insulin I'll need if abroad, in case of it being lost/stolen/ruined or me being hospitalised, and carry half in my hand luggage, half in my husband's. If I go away for 3 weeks (therefore needing 6 weeks), I would have to take approximately 35 pens with me. Any ideas on transporting this amount of pens, and especially keeping the Insulin in good condition if no fridge available ?
