Insulin can freeze when saved at 32 levels F or colder, similar to water, says Jovan Milosavljevic, MD, an assistant professor of medication at Montefiore Einstein in New York.
“When this occurs, its protein construction turns into broken,” he says. “Even when the insulin later thaws, it gained’t work the way in which it ought to.”
“To stop freezing, by no means maintain unopened insulin within the freezer or close to the again wall of the fridge,” says Hess-Fischl, including that insulated baggage can be found to maintain insulin at an applicable temperature.
Within the winter, try to be particularly cautious about the way you carry your insulin. Leaving a vial or pen outdoor in a backpack, purse, or automobile might simply expose it to freezing temperatures. If you happen to’re spending the day snowboarding or sledding and even simply buying, keep conscious of the insulin you retain in your particular person in order that it doesn’t freeze.
“Preserve insulin near your physique, like inside a jacket, and take into account an insulated pouch when touring or spending lengthy intervals outdoor so the temperature stays safely above about 40 levels F,” Dr. Milosavljevic says.
