insulin storage

Do you keep the Lantus pen in the refrigerator? Injecting cold insulin will cause a burning sensation. Take the pen out of the refrigerator 20 or 30 minutes before you inject to allow the insulin to warm up to room temperature. That will eliminate the burning sensation from cold insulin. If you do refrigerate the insulin pen that you are currently using, you should also know that all the insulin pen manufacturers recommend not doing that。

Cold insulin can be kind of uncomfortable... or not... sometimes I notice the cold, but not often. But anyway, the currently-being-used vial or pen doesn't need refrigeration. Just protect it from heat (don't store near a radiator, don't leave it in a parked car, don't leave it somewhere in direct sunlight, don't take it to a beach or park in the summer unless in a cooler bag), but don't let it freeze anywhere either, and then just use your noodle about keeping it clean (ordinary sensible hygiene rules apply).

Any extra supply of unopened vials or pens DO need to be refrigerated, however. They'll stay fresh until the expiration date on their labels. But once a vial or pen is opened, the insulin is supposed to be used within 30 days and any leftovers discarded.
