How to Store Your Insulin
Tips on Insulin Storage
Check the expiration date first. Do not use insulin past expiration.
- Keeping your ‘current’ insulin (i.e., a few days or a week’s supply) at room temperature can help alleviate injection discomfort.
- Insulin available in vials can usually be stored at room temperature for about a month. Insulin in a pen should be stored at room temperature once in use. Expiration date of insulin pens can vary depending upon the type of insulin. For disposable pens, the entire device is discarded when empty or when expiration date is reached.
- Store extra insulin (2-3 week supply or more) in the refrigerator.
- Do not expose insulin to excessive cold (e.g., in a freezer) or heat (e.g., in direct sunlight).
