Hia - as advised by my DSN if I'm away for a day shopping, which happens a bit too regularly for my husbands' liking!, I take my pens as a back in case I have problems with my pump. Yesterday it was a normal cold day and when I got back in at night I just put the pens back in the fridge. I was just thinking if I took my pens out of the fridge on average 5-7 times a month for a day at a time but then put them back at the end of the day will this affect the insulin significantly if I do need to use them as i think the advise 30 days outside of the refrigerator normally. Maybe I'm over analysing !! :crazy:
