Due to a power loss when away, my insulin (Novarapid & Levemir) were left in the fridge with no power for up to 24 hrs. Door wasn't opened during this time. I've since just left in the fridge to cool down again. Unsure how hot the kitchen was (North East Scotland so not extreme) but over 60F.

Anyone think if this insulin may have been affected by this warming up?

Thanks.

If the door was shut ,and the room was at normal temperature I would think that your insulin would be fine.A fridge will usually stay cool for hours. I have carried a pen in my pocket for a day before now with no bad effects. If the insulin is still showing as clear in the syringe you should be fine

Previous post about broken pens, I asked about carrying spare cartridges, someone said that Insulin as long as it doesn't get too hot or cold can be out of the fridge for 30 days, I have had a spare and one in my pen for days at room temp (I always worry when in hot countries about this).

Thanks for info.

I was aware of the "30 day" rule, but my case was slightly different in that the insulin would have warmed up to some extent then been chilled again before use. Suppose its similar to the labels on food that say it mustn't be refrozen after thawing out.
