Similarly, how long is insulin good once opened?

Once you stick a needle in the vial, it is OPEN. OPEN vials can be stored in the fridge or at CONTROLLED room temperature. Regardless of where it is stored, OPEN insulin will only last 28 days before it must be thrown in the trash.

Furthermore, can insulin go bad? A: Your insulin might still be good after the expiration date on the box, or after 28 days at room temperature, but it's not guaranteed to be good. You should also know that Lantus insulin and the rapid insulins (Humalog and Novolog) spoil faster than Regular and NPH insulin.

In respect to this, should Humulin R be refrigerated?

Not in-use (unopened): Humulin R U-100 vials not in-use should be stored in a refrigerator (2° to 8°C [36° to 46°F]), but not in the freezer. In-use (opened): The Humulin R U-100 vial currently in-use can be kept unrefrigerated as long as it is kept as cool as possible [below 30°C (86°F)] away from heat and light.

How long can you keep unopened insulin in the refrigerator?

Store newly purchased, unopened bottles of insulin in the refrigerator in their original carton to keep them clean and protected from light. When you're ready to use a bottle of insulin, you can remove it from the fridge and generally keep it at room temperature (below 86 degrees F) for up to one month.
