How should I store my insulin bottles (vials)?
New (unused) bottles:
Keep new bottles in the fridge until you are ready to use them.
Throw out insulin bottles that are past their expiration dates, even if they were stored in the fridge.
Opened (used) bottles:
Keep used bottles at room temperature in the kitchen or bedroom.
Keep away from light and heat.
Check each insulin bottle’s guide to see how long each type of insulin lasts at room temperature. They may not be the same.
