Is it safe to take insulin that has frozen?

Insulin freezes almost as easily as water, and can be damaged by too much heat, so it's important to keep it protected from the elements. Once it's been opened, you can keep your insulin at room temperature for one month. Using insulin that's been frozen is dangerous, because if the protein has been damaged, it could mean you're not getting an adequate dose.
