How long does glulisine last in pumps? What insulins can people buy without a prescription? What is the longest lasting insulin? If you want to learn the answers to these questions an more, we are here to help!

With the high price of insulin, many people with diabetes are reluctant to throw half-used bottles or pens of insulin away.

With the pandemic and ongoing insulin pricing issues, many people are struggling to pay for their insulin. Armed with information, we can help people maximize their insulin use and optimize their choices.

By knowing how long different insulin formulations last when kept at room temperature (temps up to 86 degrees), we can help people use their insulin as long as it is safe and recommended.

We usually say insulin is good for about 28 days. This is correct for many insulins, but not all.

For example, a vial of Human Regular insulin is good at room temp for 42 days. Degludec (Tresiba) is good for 56 days and Novolin 70/30 vial is good for 42 days. Glulisine (Apidra) expires after 2 days in an insulin pump, but lasts for 28 days in a vial.
