Correct. Just like you wouldn’t drink spoiled milk, you shouldn’t inject expired insulin!

The recommended temperature for storing insulin is in a refrigerator between 36°F and 46°F (2°C to 8°C).

Once opened, most insulin can be stored at room temperature, which generally should be between 59°F and 86°F (15°C to 30°C), for up to 28 days. [check your brand for details]
