Hello good.I share this personal and recent experience, because surely many people, just like me, do not know, so that the same thing does not happen to me and they take a scare.Recently I had to travel by plane, and as I worried that in the controls they would put me in or even force me to leave the insulin (with the excuse of the liquids or something similar), because I decided to put a couple of bolis of Lantus and novorapidIn the suitcase I billed, just in case.On the return trip I billed these same bolis.Each route was about 3 hours of flight.Already back at home, soon, I started having unusual values, I did not go down from 180 and many times I had 300 and peak, and that eating less, clicking on me increasing dose and then on top of that trying to correct ... I was like thisDays without knowing what was happening, until I realized that I was using just those bolis that were in the winery, I looked on the Internet and confirmed my suspicions, and that is that the insulins degrade in the plane's cellar.I immediately started using other bolis that I did not take on that trip and returned to the usual values (which is not that they are very well lately, but nothing to see).Do not bill your insulins, always take them in hand luggage.Greetings.
