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.
