I got myself a thermometer for the fridge. One of these wireless ones where you place the actual thermometers in various places in the fridge and they transmit the values to a display that is kept outside. This display also shows me the lowest and highest temperature recorded.
Well, this display now tells me that even though I set my fridge to max, the temperatures in the vegetable drawer lie between 10 and 14 degrees celsius. Insulin should be kept at 2-8 degrees celsius.
This worries me because I didn’t realize the fridge is that busted. I ordered a new one, but it will be about 1 1/2 weeks until I get it. Plus, after I got released from the hospital after diagnosis early March this year, I was also given pre-filled Humalog and Lantus pens, which I wanted to save up for emergencies… but perhaps the fridge was running that “hot” all the time, so … should I be concerned? Should I throw away these pre-filled pens?
I also have two Tresiba and two Toujeo pens my endo gave me for trying out. I got them on July 20th, and they are probably ok. I also got new Lantus and Humalog cartridges sometime afterwards (I get these automatically), they are most likely also fine. But … official recommendations consider 15 degrees celsious to be room temperature, and 14 degrees is only a little below that. At “room temperature”, official recommendations state to not use insulin after 28 days!
So, am I right to assume that my insulin is most likely still OK? And what about the pre-filled pens?
