In brief: Yes
Store new (unopened) vials in the refrigerator, between 36 and 46 degrees f (2 and 8 degrees c).
Do not freeze. Certain brands of the medicine may be stored at room temperature, below 77 degrees f (25 degrees c) for up to 6 weeks (42 days), if refrigeration is not possible. Check with your pharmacist to see if your brand can be stored at room temperature. Keep Humulin (insulin) N vials in the carton to prot.

In brief: Depends
Humilin bottles not in use should be stored in a fridge 36-46 f but not in the freezer. Humulin (insulin) bottle you are currently using can be kept unrefrigerated as long as it is kept as cool as possible (below 86 f) away from heat and light.
In use bottle should be used within 31 days or be thrown out. Hope this helps.
