Always consult with your healthcare provider if you have any questions or concerns about your insulin storage practices.

Does Humulin R need to be refrigerated?

Humulin R does need to be refrigerated until you are ready to use it. The manufacturer recommends storing unopened vials or pens in the refrigerator at a temperature between 36°F to 46°F (2°C to 8°C). This storage method helps maintain the insulin’s potency and effectiveness for its full shelf life, which is typically until the expiration date provided on the package.

Once you have opened a vial or pen, you can store it at room temperature (below 86°F or 30°C) for up to 28 days. It is crucial to avoid exposing the insulin to direct heat or sunlight, as these conditions can degrade its effectiveness over time. Always check the appearance of the insulin and discard any that looks cloudy or discolored.

What should I do if I accidentally freeze Humulin R?

If Humulin R has been accidentally frozen, it is essential not to use it. Freezing can alter the structure of the insulin, making it less effective for managing blood glucose levels. If you suspect that your Humulin R has been frozen, it’s best to check for ice crystals or other signs of damage before discarding it.

You should replace the frozen vial or pen with a new one stored according to the guidelines. If you’re unsure about how to proceed, consult your healthcare provider or pharmacist for guidance on how to manage your insulin supplies effectively.

How long can Humulin R be kept at room temperature?

Humulin R can be stored at room temperature for up to 28 days once the vial or pen has been opened. It is essential to keep it at temperatures below 86°F (30°C) during this time.
