Insulin Pens Are Welcome Back To The Fridge!

We all know that unopened insulin must be kept in the refrigerator. But once in use can we put it back in the fridge to protect it from excessive heat?

This guideline that causes confusion among users is now being revoked by one manufacturer. Let’s try to understand the reasoning behind it and what it means for users now. What?
